The Free Translation Project is a way to get maintainers of free software, translators, and users all together, so that free software will gradually become able to speak many languages. A few packages already provide translations for their messages. If you found this 'ABOUT-NLS' file inside a distribution, you may assume that the distributed package does use GNU 'gettext' internally, itself available at your nearest GNU archive site. But you do _not_ need to install GNU 'gettext' prior to configuring, installing or using this package with messages translated. Installers will find here some useful hints. These notes also explain how users should proceed for getting the programs to use the available translations. They tell how people wanting to contribute and work on translations can contact the appropriate team. 1.1 INSTALL Matters =================== Some packages are "localizable" when properly installed; the programs they contain can be made to speak your own native language. Most such packages use GNU 'gettext'. Other packages have their own ways to internationalization, predating GNU 'gettext'. By default, this package will be installed to allow translation of messages. It will automatically detect whether the system already provides the GNU 'gettext' functions. Installers may use special options at configuration time for changing the default behaviour. The command: ./configure --disable-nls will _totally_ disable translation of messages. When you already have GNU 'gettext' installed on your system and run configure without an option for your new package, 'configure' will probably detect the previously built and installed 'libintl' library and will decide to use it. If not, you may have to to use the '--with-libintl-prefix' option to tell 'configure' where to look for it. Internationalized packages usually have many 'po/LL.po' files, where LL gives an ISO 639 two-letter code identifying the language. Unless translations have been forbidden at 'configure' time by using the '--disable-nls' switch, all available translations are installed together with the package. However, the environment variable 'LINGUAS' may be set, prior to configuration, to limit the installed set. 'LINGUAS' should then contain a space separated list of two-letter codes, stating which languages are allowed. 1.2 Using This Package ====================== As a user, if your language has been installed for this package, you only have to set the 'LANG' environment variable to the appropriate 'LL_CC' combination. If you happen to have the 'LC_ALL' or some other 'LC_xxx' environment variables set, you should unset them before setting 'LANG', otherwise the setting of 'LANG' will not have the desired effect. Here 'LL' is an ISO 639 two-letter language code, and 'CC' is an ISO 3166 two-letter country code. For example, let's suppose that you speak German and live in Germany. At the shell prompt, merely execute 'setenv LANG de_DE' (in 'csh'), 'export LANG; LANG=de_DE' (in 'sh') or 'export LANG=de_DE' (in 'bash'). This can be done from your '.login' or '.profile' file, once and for all. You might think that the country code specification is redundant. But in fact, some languages have dialects in different countries. For example, 'de_AT' is used for Austria, and 'pt_BR' for Brazil. The country code serves to distinguish the dialects. The locale naming convention of 'LL_CC', with 'LL' denoting the language and 'CC' denoting the country, is the one use on systems based on GNU libc. On other systems, some variations of this scheme are used, such as 'LL' or 'LL_CC.ENCODING'. You can get the list of locales supported by your system for your language by running the command 'locale -a | grep '^LL''. Not all programs have translations for all languages. By default, an English message is shown in place of a nonexistent translation. If you understand other languages, you can set up a priority list of languages. This is done through a different environment variable, called 'LANGUAGE'. GNU 'gettext' gives preference to 'LANGUAGE' over 'LANG' for the purpose of message handling, but you still need to have 'LANG' set to the primary language; this is required by other parts of the system libraries. For example, some Swedish users who would rather read translations in German than English for when Swedish is not available, set 'LANGUAGE' to 'sv:de' while leaving 'LANG' to 'sv_SE'. Special advice for Norwegian users: The language code for Norwegian bokma*l changed from 'no' to 'nb' recently (in 2003). During the transition period, while some message catalogs for this language are installed under 'nb' and some older ones under 'no', it's recommended for Norwegian users to set 'LANGUAGE' to 'nb:no' so that both newer and older translations are used. In the 'LANGUAGE' environment variable, but not in the 'LANG' environment variable, 'LL_CC' combinations can be abbreviated as 'LL' to denote the language's main dialect. For example, 'de' is equivalent to 'de_DE' (German as spoken in Germany), and 'pt' to 'pt_PT' (Portuguese as spoken in Portugal) in this context. 1.3 Translating Teams ===================== For the Free Translation Project to be a success, we need interested people who like their own language and write it well, and who are also able to synergize with other translators speaking the same language. Each translation team has its own mailing list. The up-to-date list of teams can be found at the Free Translation Project's homepage, 'http://translationproject.org/', in the "Teams" area. If you'd like to volunteer to _work_ at translating messages, you should become a member of the translating team for your own language. The subscribing address is _not_ the same as the list itself, it has '-request' appended. For example, speakers of Swedish can send a message to 'sv-request@li.org', having this message body: subscribe Keep in mind that team members are expected to participate _actively_ in translations, or at solving translational difficulties, rather than merely lurking around. If your team does not exist yet and you want to start one, or if you are unsure about what to do or how to get started, please write to 'coordinator@translationproject.org' to reach the coordinator for all translator teams. The English team is special. It works at improving and uniformizing the terminology in use. Proven linguistic skills are praised more than programming skills, here. 1.4 Available Packages ====================== Languages are not equally supported in all packages. The following matrix shows the current state of internationalization, as of Jun 2014. The matrix shows, in regard of each package, for which languages PO files have been submitted to translation coordination, with a translation percentage of at least 50%.

us expect. This is because a few extra PO files are used for implementing regional variants of languages, or language dialects. For a PO file in the matrix above to be effective, the package to which it applies should also have been internationalized and distributed as such by its maintainer. There might be an observable lag between the mere existence a PO file and its wide availability in a distribution. If Jun 2014 seems to be old, you may fetch a more recent copy of this 'ABOUT-NLS' file on most GNU archive sites. The most up-to-date matrix with full percentage details can be found at 'http://translationproject.org/extra/matrix.html'. 1.5 Using 'gettext' in new packages =================================== If you are writing a freely available program and want to internationalize it you are welcome to use GNU 'gettext' in your package. Of course you have to respect the GNU Lesser General Public License which covers the use of the GNU 'gettext' library. This means in particular that even non-free programs can use 'libintl' as a shared library, whereas only free software can use 'libintl' as a static library or use modified versions of 'libintl'. Once the sources are changed appropriately and the setup can handle the use of 'gettext' the only thing missing are the translations. The Free Translation Project is also available for packages which are not developed inside the GNU project. Therefore the information given above applies also for every other Free Software Project. Contact 'coordinator@translationproject.org' to make the '.pot' files available to the translation teams. zbar-0.23/examples/0000775000175000017500000000000013471606255011226

Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] ### Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. ### TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION **0.** This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. **1.** You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. **2.** You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: - **a)** The modified work must itself be a software library. - **b)** You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. - **c)** You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. - **d)** If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. **3.** You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. **4.** You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. **5.** A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. **6.** As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: - **a)** Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) - **b)** Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. - **c)** Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. - **d)** If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. - **e)** Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. **7.** You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: - **a)** Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. - **b)** Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. **8.** You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. **9.** You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. **10.** Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. **11.** If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. **12.** If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. **13.** The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. **14.** If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. **NO WARRANTY** **15.** BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. **16.** IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. ### END OF TERMS AND CONDITIONS ### How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. one line to give the library's name and an idea of what it does. Copyright (C) year name of author This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary.

Here is a matrix of mmap possibilities: mmap private not fixed mmap private fixed at somewhere currently unmapped mmap private fixed at somewhere already mapped mmap shared not fixed mmap shared fixed at somewhere currently unmapped mmap shared fixed at somewhere already mapped For private mappings, we should verify that changes cannot be read() back from the file, nor mmap's back from the file at a different address. (There have been systems where private was not correctly implemented like the infamous i386 svr4.0, and systems where the VM page cache was not coherent with the file system buffer cache like early versions of FreeBSD and possibly contemporary NetBSD.) For shared mappings, we should conversely verify that changes get propagated back to all the places they're supposed to be. Grep wants private fixed already mapped.

You can embed shell variables for delayed # expansion at the time the message is displayed, but you will need to # quote other shell meta-characters carefully to prevent them being # expanded when the contents are evaled. usage='$progpath [OPTION]...' # Short help message in response to '-h' and '--help'. Add to this or # override it after sourcing this library to reflect the full set of # options your script accepts. usage_message="\ --debug enable verbose shell tracing -W, --warnings=CATEGORY report the warnings falling in CATEGORY [all] -v, --verbose verbosely report processing --version print version information and exit -h, --help print short or long help message and exit " # Additional text appended to 'usage_message' in response to '--help'. long_help_message=" Warning categories include: 'all' show all warnings 'none' turn off all the warnings 'error' warnings are treated as fatal errors" # Help message printed before fatal option parsing errors. fatal_help="Try '\$progname --help' for more information." ## ------------------------- ## ## Hook function management. ## ## ------------------------- ## # This section contains functions for adding, removing, and running hooks # to the main code.

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'.

As part of the new port, it is now possible to use ZBar Gtk bindings not only with python2/python3, but also on other languages, as it now uses GObject Introspection- GIR, with is a method to allow using libraries developed on one language on others. Several languages support it. On Windows side, support for DirectShow was added. Version 0.22.2 (2019-04-29) =========================== Some fixes to another set of Windows issues and to support Java 11. Version 0.22.1 (2019-04-25) =========================== Some fixes to allow building ZBar on Windows with MinGw. Version 0.22 (2019-02-20) ========================= Lots of improvements at zbarcam-qt, allowing it to fully configure the decoders that will be used, and the options that will be used at the decoders. Some improvements at the image scanner logic and plugin selection. Version 0.21 (2019-02-12) ========================= Added support for SQ code, and the ability of compiling ZBar with the LLVM/Clang compiler. Several bugs fixes and enhancements are also found in this release; qexisting users are encouraged to upgrade. Version 0.20.1 (2018-08-08) =========================== Minor changes at ZBar, in order to adapt to modern distributions with are removing /usr/bin/python in favor of just using python2. Also, updated some python2 scripts to work with modern distros, where the Image module is now inside PIL. Version 0.20 (2017-04-11) ========================= As upstream didn't have any version since 2009, created a ZBar fork at linuxtv.org. This release improves a lot V4L2 support, by using libv4l2 to handle formats that are alien to ZBar, making it compatible with a lot more webcam models. Qt support was also updated, making it compatible with Qt5. ZBar now have two other GUI applications (zbarcam-qt and zbarcam-gtk). With zbarcam-qt, it is now possible to adjust the camera controls, making easier to read barcodes using a camera. Version 0.10 (2009-10-23) ========================= ZBar goes 2D! This release introduces support for QR Code, developed by our new project member, Timothy Terriberry. Timothy is an image processing master, providing this sophisticated functionality using only integer arithmetic and maintaining an extremely small image size. Feel free to drop in on #zbar over at freenode to welcome Timothy (aka derf) to the project and congratulate him on his awesome work. Several bugs fixes and enhancements are also found in this release; existing users are encouraged to upgrade. Version 0.9 (2009-08-31) ======================== Introducing ZBar for Windows! So far we only have straight ports of the command line applications, but work on a cross-platform GUI has already begun. This release also has a few scanner/decoder enhancements and fixes several bugs. Many internal changes are represented, so please open a support request if you experience any problems. Version 0.8 (2009-06-05) ======================== This is a bugfix release just to clean up a few issues found in the last release. Existing users are encouraged to upgrade to pick up these fixes. Version 0.7 (2009-04-21) ======================== Welcome to ZBar! In addition to finalizing the project name change, this release adds new bindings for Python and fixes a few bugs with the Perl interface. The decoder also has several new features and addresses missing checks that will improve reliability with excessively noisy images. Version 0.6 (2009-02-28) ======================== This release fixes many bugs and adds several improvements suggested by users: support for decoding UPC-E is finished. zebraimg is now able to scan all pages of a document (such as PDF or TIFF) and the new XML output includes the page where each barcode is found. Camera support has been significantly improved, including the addition of JPEG image formats. Perl bindings make it even easier to write a document or video scanning application. Finally, we are now able to offer initial support for building the base library for Windows! Version 0.5 (2008-07-25) ======================== Introducing zebra widgets! Prioritized by popular demand, this release includes fully functional barcode scanning widgets for GTK, PyGTK, and Qt. Application developers may now seamlessly integrate barcode reader support with their user interface. This release also fixes many bugs; existing users are encouraged to upgrade. Version 0.4 (2008-05-31) ======================== new support for EAN-8, Code 39 and Interleaved 2 of 5! this release also introduces the long awaited decoder configuration options and fixes several bugs Version 0.3 (2008-02-25) ======================== this is a beta release of the enhanced internal architecture. support has been added for version 2 of the video4linux API and many more image formats. several other feature enhancements and bug fixes are also included. image scanning is slightly improved for some images, but the base scan/decode function is relatively untouched. significant new code is represented in this release - all bug reports are welcome and will be addressed promptly! Version 0.2 (2007-05-16) ======================== this release introduces significant enhancements, bug fixes and new features! basic EAN-13/UPC-A reading has been improved and should now be much more reliable. by popular request, new support has been added for decoding Code 128. additionally, the build process was improved and there is even basic documentation for the application commands Version 0.1 (2007-03-24) ======================== first official Zebra release! supports basic scanning and decoding of EAN-13 and UPC-A symbols using a webcam (zebracam) or from stored image files (zebraimg). still need to add support for addons and EAN-8/UPC-E zbar-0.23/gtk/0000775000175000017500000000000013471606260010171 500000000000000zbar-0.23/gtk/zbargtk.c0000664000175000017500000006575013471225716011741 00000000000000/*------------------------------------------------------------------------ * Copyright 2008-2010 (c) Jeff Brown * * This file is part of the ZBar Bar Code Reader. * * The ZBar Bar Code Reader is free software; you can redistribute it * and/or modify it under the terms of the GNU Lesser Public License as * published by the Free Software Foundation; either version 2.1 of * the License, or (at your option) any later version. * * The ZBar Bar Code Reader is distributed in the hope that it will be * useful, but WITHOUT ANY WARRANTY; without even the implied warranty * of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This requires a working diff program to be installed on your system. =head2 --copy=I If this option is given, a copy of each file will be saved with the given suffix that contains the suggested changes. This does not require any external programs. If neither C<--patch> or C<--copy> are given, the default is to simply print the diffs for each file. This requires either C or a C program to be installed. =head2 --diff=I Manually set the diff program and options to use. The default is to use C, when installed, and output unified context diffs. =head2 --compat-version=I Tell F to check for compatibility with the given Perl version. The default is to check for compatibility with Perl version 5.003. You can use this option to reduce the output of F if you intend to be backward compatible only up to a certain Perl version. =head2 --cplusplus Usually, F will detect C++ style comments and replace them with C style comments for portability reasons. Using this option instructs F to leave C++ comments untouched. =head2 --quiet Be quiet. Don't print anything except fatal errors. =head2 --nodiag Don't output any diagnostic messages. Only portability alerts will be printed. =head2 --nohints Don't output any hints. Hints often contain useful portability notes. =head2 --nochanges Don't suggest any changes. Only give diagnostic output and hints unless these are also deactivated. =head2 --nofilter Don't filter the list of input files. By default, files not looking like source code (i.e. not *.xs, *.c, *.cc, *.cpp or *.h) are skipped. =head2 --list-provided Lists the API elements for which compatibility is provided by F. Also lists if it must be explicitly requested, if it has dependencies, and if there are hints for it. =head2 --list-unsupported Lists the API elements that are known not to be supported by F and below which version of Perl they probably won't be available or work. =head2 --api-info=I Show portability information for API elements matching I. If I is surrounded by slashes, it is interpreted as a regular expression. =head1 DESCRIPTION In order for a Perl extension (XS) module to be as portable as possible across differing versions of Perl itself, certain steps need to be taken. =over 4 =item * Including this header is the first major one. This alone will give you access to a large part of the Perl API that hasn't been available in earlier Perl releases. Use perl ppport.h --list-provided to see which API elements are provided by ppport.h. =item * You should avoid using deprecated parts of the API. For example, using global Perl variables without the C prefix is deprecated. Also, some API functions used to have a C prefix. Using this form is also deprecated. You can safely use the supported API, as F will provide wrappers for older Perl versions. =item * If you use one of a few functions that were not present in earlier versions of Perl, and that can't be provided using a macro, you have to explicitly request support for these functions by adding one or more C<#define>s in your source code before the inclusion of F. These functions will be marked C in the list shown by C<--list-provided>. Depending on whether you module has a single or multiple files that use such functions, you want either C or global variants. For a C function, use: #define NEED_function For a global function, use: #define NEED_function_GLOBAL Note that you mustn't have more than one global request for one function in your project.

Just C<#define> the macro before including C: #define DPPP_NAMESPACE MyOwnNamespace_ #include "ppport.h" The default namespace is C. =back The good thing is that most of the above can be checked by running F on your source code. See the next section for details. =head1 EXAMPLES To verify whether F is needed for your module, whether you should make any changes to your code, and whether any special defines should be used, F can be run as a Perl script to check your source code. Simply say: perl ppport.h The result will usually be a list of patches suggesting changes that should at least be acceptable, if not necessarily the most efficient solution, or a fix for all possible problems. If you know that your XS module uses features only available in newer Perl releases, if you're aware that it uses C++ comments, and if you want all suggestions as a single patch file, you could use something like this: perl ppport.h --compat-version=5.6.0 --cplusplus --patch=test.diff If you only want your code to be scanned without any suggestions for changes, use: perl ppport.h --nochanges You can specify a different C program or options, using the C<--diff> option: perl ppport.h --diff='diff -C 10' This would output context diffs with 10 lines of context. To display portability information for the C function, use: perl ppport.h --api-info=newSVpvn Since the argument to C<--api-info> can be a regular expression, you can use perl ppport.h --api-info=/_nomg$/ to display portability information for all C<_nomg> functions or perl ppport.h --api-info=/./ to display information for all known API elements. =head1 BUGS If this version of F is causing failure during the compilation of this module, please check if newer versions of either this module or C are available on CPAN before sending a bug report. If F was generated using the latest version of C and is causing failure of this module, please file a bug report using the CPAN Request Tracker at L.

It supports EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 93, Code 39, Codabar, Interleaved 2 of 5 and QR Code. These are the bindings for interacting directly with the library from Perl. =head1 REFERENCE =head2 Functions =over 4 =item version() Returns the version of the zbar library as "I.I". =item increase_verbosity() Increases global library debug by one level. =item set_verbosity(I) Sets global library debug to the indicated level. Higher numbers give more verbosity. =item parse_config(I) Parse a decoder configuration setting into a list containing the symbology constant, config constant, and value to set. See the documentation for C/C for available configuration options. =back =head2 Constants Width stream "color" constants: =over 4 =item SPACE Light area or space between bars. =item BAR Dark area or colored bar segment. =back Decoder configuration constants: =over 4 =item Config::ENABLE =item Config::ADD_CHECK =item Config::EMIT_CHECK =item Config::ASCII =item Config::MIN_LEN =item Config::MAX_LEN =item Config::POSITION =item Config::X_DENSITY =item Config::Y_DENSITY =back Symbology modifier constants: =over 4 =item Modifier::GS1 =item Modifier::AIM =back Symbol orientation constants: =over 4 =item Orient::UNKNOWN =item Orient::UP =item Orient::RIGHT =item Orient::DOWN =item Orient::LEFT =back =head1 SEE ALSO Barcode::ZBar::Processor, Barcode::ZBar::ImageScanner, Barcode::ZBar::Image, Barcode::ZBar::Symbol, Barcode::ZBar::Scanner, Barcode::ZBar::Decoder zbarimg(1), zbarcam(1) http://zbar.sf.net =head1 AUTHOR Jeff Brown, Espadix@users.sourceforge.netE =head1 COPYRIGHT AND LICENSE Copyright 2008-2010 (c) Jeff Brown Espadix@users.sourceforge.netE The ZBar Bar Code Reader is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. =cut zbar-0.23/perl/ZBar.xs0000664000175000017500000005701613471225716011514 00000000000000//------------------------------------------------------------------------ // Copyright 2008-2010 (c) Jeff Brown // // This file is part of the ZBar Bar Code Reader. // // The ZBar Bar Code Reader is free software; you can redistribute it // and/or modify it under the terms of the GNU Lesser Public License as // published by the Free Software Foundation; either version 2.1 of // the License, or (at your option) any later version. // // The ZBar Bar Code Reader is distributed in the hope that it will be // useful, but WITHOUT ANY WARRANTY; without even the implied warranty // of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded.

Note that some symbologies can encode binary data. =item get_quality() Confidence metric. An unscaled integer value that indicates something (intentionally unspecified) about the reliability of this result relative to another. Larger values are better than smaller values, where "large" and "small" are application dependent. Expect this definition to become more specific as the metric is enhanced. =item get_count() Current cache count of the symbol. This integer value provides inter-scan reliability and redundancy information if enabled at the Barcode::ZBar::ImageScanner. =item get_orientation() General orientation of decoded symbol. This returns one of the Barcode::ZBar::Orient constants, which provide a coarse, axis-aligned indication of symbol orientation. =item get_components() Components of a composite result.

It has interfaces to scan images or video and to optionally display a video/image preview to a window. This interface is not well suited for integration with an existing GUI, as the library manages the optional preview window and any user interaction. Use a Barcode::ZBar::ImageScanner or Investigate the available widget interfaces for GUI applications. =head1 REFERENCE =head2 Methods =over 4 =item new() Create a new bar code reader instance. =item init([I], [I]) Open a video input device and/or prepare to display output. =item set_data_handler([I], [I]) Setup a callback to process results whenever new results are available from the video stream or a static image. The specified callable will be invoked with the associated Barcode::ZBar::Processor object and I as arguments. Closure may be achieved either using standard Perl closure or by manually passing a scalar via I. =item is_visible() =item set_visible([I]) Test/set visibility of the output window. =item set_active([I]) Enable/disable video streaming and scanning for bar codes. =item get_results() Return a list of Barcode::ZBar::Symbol results from the last scanned image or video frame. =item user_wait([I]) Wait for the user to press a key/button or close the window. Bar codes will continue to be processed if video is active. =item process_one([I]) Enable video and scan until at least one barcode is found. Note that multiple results may still be returned. =item process_image([I]) Scan a Barcode::ZBar::Image for bar codes. =item parse_config(I) Apply a decoder configuration setting. See the documentation for C/C for available configuration options. =item request_size(I, I) Request a preferred size for the video image from the device.

It works by trying to compile this: int main(void) { return 0; } and linking it to the specified libraries. If something pops out the end which looks executable, then we know that it worked. That tiny program is built once for each library that you specify, and (without linking) once for each header file. =head1 FUNCTIONS All of these take the same named parameters and are exported by default. To avoid exporting them, C. =head2 assert_lib This takes several named parameters, all of which are optional, and dies with an error message if any of the libraries listed can not be found. B: dying in a Makefile.PL or Build.PL may provoke a 'FAIL' report from CPAN Testers' automated smoke testers. Use C instead. The named parameters are: =over =item lib Must be either a string with the name of a single library or a reference to an array of strings of library names. Depending on the compiler found, library names will be fed to the compiler either as C<-l> arguments or as C<.lib> file names. (E.g. C<-ljpeg> or C) =item libpath a string or an array of strings representing additional paths to search for libraries. =item LIBS a C-style space-seperated list of libraries (each preceded by '-l') and directories (preceded by '-L'). =back And libraries are no use without header files, so ... =over =item header Must be either a string with the name of a single header file or a reference to an array of strings of header file names. =item incpath a string or an array of strings representing additional paths to search for headers. =item INC a C-style space-seperated list of incpaths, each preceded by '-I'. =back =head2 check_lib_or_exit This behaves exactly the same as C except that instead of dying, it warns (with exactly the same error message) and exits. This is intended for use in Makefile.PL / Build.PL when you might want to prompt the user for various paths and things before checking that what they've told you is sane. If any library or header is missing, it exits with an exit value of 0 to avoid causing a CPAN Testers 'FAIL' report. CPAN Testers should ignore this result -- which is what you want if an external library dependency is not available. =cut sub check_lib_or_exit { eval 'assert_lib(@_)'; if($@) { warn $@; exit; } } sub assert_lib { my %args = @_; my (@libs, @libpaths, @headers, @incpaths); # FIXME: these four just SCREAM "refactor" at me @libs = (ref($args{lib}) ? @{$args{lib}} : $args{lib}) if $args{lib}; @libpaths = (ref($args{libpath}) ? @{$args{libpath}} : $args{libpath}) if $args{libpath}; @headers = (ref($args{header}) ? @{$args{header}} : $args{header}) if $args{header}; @incpaths = (ref($args{incpath}) ? @{$args{incpath}} : $args{incpath}) if $args{incpath}; # work-a-like for Makefile.PL's LIBS and INC arguments if(defined($args{LIBS})) { foreach my $arg (split(/\s+/, $args{LIBS})) { die("LIBS argument badly-formed: $arg\n") unless($arg =~ /^-l/i); push @{$arg =~ /^-l/ ? \@libs : \@libpaths}, substr($arg, 2); } } if(defined($args{INC})) { foreach my $arg (split(/\s+/, $args{INC})) { die("INC argument badly-formed: $arg\n") unless($arg =~ /^-I/); push @incpaths, substr($arg, 2); } } my @cc = _findcc(); my @missing; # first figure out which headers we can't find ... for my $header (@headers) { my($ch, $cfile) = File::Temp::tempfile( 'assertlibXXXXXXXX', SUFFIX => '.c' ); print $ch qq{#include <$header>\nint main(void) { return 0; }\n}; close($ch); my $exefile = File::Temp::mktemp( 'assertlibXXXXXXXX' ) . $Config{_exe}; my @sys_cmd; # FIXME: re-factor - almost identical code later when linking if ( $Config{cc} eq 'cl' ) { # Microsoft compiler require Win32; @sys_cmd = (@cc, $cfile, "/Fe$exefile", (map { '/I'.Win32::GetShortPathName($_) } @incpaths)); } elsif($Config{cc} =~ /bcc32(\.exe)?/) { # Borland @sys_cmd = (@cc, (map { "-I$_" } @incpaths), "-o$exefile", $cfile); } else { # Unix-ish # gcc, Sun, AIX (gcc, cc) @sys_cmd = (@cc, $cfile, (map { "-I$_" } @incpaths), "-o", "$exefile"); } warn "# @sys_cmd\n" if $args{debug}; my $rv = $args{debug} ? system(@sys_cmd) : _quiet_system(@sys_cmd); push @missing, $header if $rv != 0 || ! -x $exefile; _cleanup_exe($exefile); unlink $cfile; } # now do each library in turn with no headers my($ch, $cfile) = File::Temp::tempfile( 'assertlibXXXXXXXX', SUFFIX => '.c' ); print $ch "int main(void) { return 0; }\n"; close($ch); for my $lib ( @libs ) { my $exefile = File::Temp::mktemp( 'assertlibXXXXXXXX' ) . $Config{_exe}; my @sys_cmd; if ( $Config{cc} eq 'cl' ) { # Microsoft compiler require Win32; my @libpath = map { q{/libpath:} .

It supports EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 93, Code 39, Codabar, Interleaved 2 of 5, QR Code and SQ Code. Included with the library are basic applications for decoding captured bar code images and using a video device (eg, webcam) as a bar code scanner. For application developers, language bindings are included for C, C++, Python 2 and Perl as well as GUI widgets for Qt, GTK and PyGTK 2.0. Zbar also supports sending the scanned codes via dbus, allowing its integration with other applications. Check the ZBar home page for the latest release, mailing lists, etc.: - Tarballs with ZBar can be obtained from: - License information can be found in `COPYING`. You may find some outdated documentation at the original ZBar's site at Sourceforge, but please notice that the content there is not updated for ages: http://zbar.sourceforge.net/ BUILDING ======== See `INSTALL.md` for generic configuration and build instructions. Usually, all you need to do is to run: autoreconf -vfi ./configure make * NOTE On version 0.23, since the support for gtk3 and python3 are new, the default is to use gtk2 and python2. If you want to use gtk3 and python3, you should have the development packages for them, and run: autoreconf -vfi ./configure --with-gtk=auto --with-python=auto make This will make the building system to seek for the latest versions for gtk and python. The scanner/decoder library itself only requires a few standard library functions which should be available almost anywhere. The zbarcam program uses the video4linux API (v4l1 or v4l2) to access the video device. This interface is part of the linux kernel, a 3.16 kernel or upper is recommended for full support. More information is available at: - `pkg-config` is used to locate installed libraries. You should have installed `pkg-config` if you need any of the remaining components. pkg-config may be obtained from: - The `zbarimg` program uses `ImageMagick` to read image files in many different formats. You will need at least `ImageMagick` version 6.2.6 if you want to scan image files. You may also use `GraphicsMagick` package instead. `ImageMagick` may be obtained from: - Qt Widget --------- The Qt widget requires Qt4 or Qt5. You will need Qt if you would like to use or develop a Qt GUI application with an integrated bar code scanning widget. Qt4 may be obtained from: - Gtk Widget ---------- The GTK+ widget requires GTK+-2.x or GTK+3.x. You will need GTK+ if you would like to use or develop a GTK+ GUI application with an integrated bar code scanning widget. GTK+ may be obtained from: - Python widgets -------------- **Python 2 legacy Gtk widget** The PyGTK 2.0/pygobject 2.0 wrapper for the GTK+ 2.x widget requires Python 2, PyGTK. You will need to enable both pygtk2 and gtk2 if you would like to use or develop a Python 2 GUI application with an integrated bar code scanning widget. PyGTK may be obtained from: - **Python 2 or 3 GIR Gtk widget** The GObject Introspection (GIR) wrapper for GTK+ widget is compatible with PyGObject, with works with either Python version 2 or 3. You will need to enable both Gtk and Python in order to use or develop a Python application with an integrated bar code scanning and webcam support. In order to build it, you need the required dependencies for GIR development. The actual package depends on the distribution. On Fedora, it is `pygobject3-devel`. On Debian/Ubuntu, it is `libgirepository1.0-dev` and `gir1.2-gtk-3.0`. While GIR builds with Gtk2, It is strongly recommended to use GTK+ version 3.x, as there are known issues with version 2.x and GIR, with will likely make it to fail. A test script can be built and run with: `make check-gi`. Instructions about how to use are GIR on Python are available at: - **Python bindings** The Python bindings require Python 2 and provide only non-GUI functions. You will need Python and PIL or Pillow if you would like to scan images or video directly using Python. Python is available from: - Perl Widget ----------- The Perl bindings require Perl (version 5). You will need Perl if you would like to scan images or video directly using Perl. Perl is available from: - If required libraries are not available you may disable building for the corresponding component using configure (see configure --help). The Perl bindings must be built separately after installing the library. see: - `perl/README` Java Widget ----------- The Java ZBar widget uses Java Native Interface (JNI), meaning that the widget will contain machine-dependent code. It works with Java version 7 and above. Java open JDK is available from: - RUNNING ======= `make install` will install the library and application programs. Run `zbarcam-qt` or `zbarcam` to start the video scanner. Use `zbarimg ` to decode a saved image file. Check the manual to find specific options for each program. DBUS TESTING ============ In order to test if dbus is working, you could use: $ dbus-monitor --system interface=org.linuxtv.Zbar1.Code or build the test programs with: $ make test_progs And run: $ ./test/test_dbus With that, running this command on a separate shell: $ ./zbarimg/zbarimg examples/code-128.png CODE-128:https://github.com/mchehab/zbar scanned 1 barcode symbols from 1 images in 0.01 seconds Will produce this output at test_dbus shell window: Waiting for Zbar events Type = CODE-128 Value = https://github.com/mchehab/zbar REPORTING BUGS ============== Bugs can be reported on the project page: - Please include the ZBar version number and a detailed description of the problem.

(patch #1723536) * finally add HACKING to distribution/install (bug #1698202) * add extra documentation files to install (README NEWS INSTALL, etc) * Debian package patch for 0.2 - thanks to V�t Hrachov�: - add libsdl1.2-dev as a build dependency - update automake (>= 1:1.10) as a build dependency - new package version 0.2: * update distribution to include debian packaging * add consistency checking to zebracam * add redundant output suppression to zebraimg * fix couple of Code 128 decode table bugs * fix reversed Code 128 decode * add outstanding scanner edge flush to new_scan() - API change: scanner reset/new_scan() now return scan/decode status - update zebracam and zebraimg to call this between each walker pass (interface still needs improvement...) => improves in scan results for many cases * fix dbg_scan filename generation so results go in local directory * continue Code 128 refinement - finish character set C decode/expansion - add per-character validation - resolve scan direction in separate postprocessing pass before handling ASCII conversion - add several img_walker passes parallel to major axis (for long symbols) - add simple character set C example to test_decode * promote zebraimg images to TrueColor so colored scan pattern always shows * more dbg_scan tweaks * significant scanner improvements - changed "classic" [-1 0 1] first differential kernel to [-1 1] to improve minimum edge resolution to single pixel elements => still need to do some more research and validate assumptions - adaptive thresholding fixes - adjusted filtering for better edge detection - separate constants out to defines (FIXME add config API?) * fix EAN-13 secondary determinant decoding * dbg_scan tweaks to make annotations smaller/more usable * add get_color() interface to decoder * annotated zebraimg scan pattern for marginally useful high-level debug * random include cleanup * cleanup 64-bit compile warnings in zebraimg (bug #1712504) * add first-pass partial support for Code 128 - separate out more EAN state from shared state - internal interface changes - finish dynamic buffer management - add shared resource locking - add Code 128 to test_decode program => still needs additional functionality and plenty of debug => reading both Code 128 *and* EAN still destabilized * add diagnostic program test_video to dump more verbose video debug * incorporate documentation into Debian package - thanks to V�t Hrachov� for the patch! * fix VPATH doc builds (requires automake-1.10 and autoconf-2.61) * build and dist fixes - suppress documentation rebuilds in distributed sources * add Debian packaging sources - thanks to V�t Hrachov� for the patch! * add DocBook template and build infrastructure * add manpages for zebracam and zebraimg * add GNU standard options to zebracam and zebraimg * internal decoder restructuring to support additional symbologies - separated out 1-D decoder infrastructure into generic internal API - moved EAN/UPC specific decoding into it's own module * fix confusing configure behavior which quietly avoided building targets with missing dependencies(?!) configure will now fail with a descriptive error message if you do not have Magick++ and fail to specify --without-imagemagick or do not have SDL and fail to specify --without-sdl * add configure summary describing what will be built (req #1698196) * fix parity encoding in test_decode and add decoded symbol output * introduce Code 128 symbol type * increase width of zebra_symbol_type_t to 16 bits * add HACKING (bug #1698202) version 0.1: * add NEWS and ChangeLog * fix some config/build issues found on other boxes * add missing ImageWalker install * fix scanner runaway threshold calculation bug * fix zebracam/zebraimg bugs overwriting currently scanning image w/scan pattern * add c++ interface to img_walker * apply ImageWalker to zebraimg * add decoder soft reset on partial mismatch * finish basic decoder symbol assembly/reporting * add decoder symbol checksum verification * add callback API option to decoder for "async" symbol processing * add "image walker" library API to trace scan pattern over 2D images * apply image walker to zebracam (C++/zebraimg scan pattern still TBD) * add audio feedback to zebracam (still has long latency) * add zebracam key cmd to dump frame to file (for debugging) * fixes for decoder/scanner reset/new_scan * fixes to scanner initialization and algorithm tweaks * made decoder less sensitive to violated quiet-zone * apply zebraimg workaround for imagemagick image display bug * add string names for symbol types to library and API to access them * add dbg_scan test program for visually debugging image scanner (and decoder) * add test_walk for basic image walker sanity/debug * removed recursive makes in favor of monolithic build * renamed some makefiles accordingly * finished some final symbol data construction * added result callbacks to decoder APIs for data reporting * zebraimg hooks into callback * zebracam still seems to "hang" in undecodeable state? * populate svn with current sources. * most of the basic functionality is included and working. * still need to combine final decode data, finish addons, etc (see TODO). * c++ wrappers are included and tested, but API may need tweaked. * zebraimg and zebracam basically working but need cleanup/polish. * need to create some basic documentation... * initial repository layout zbar-0.23/python/0000775000175000017500000000000013471606255010731 500000000000000zbar-0.23/python/exception.c0000664000175000017500000000742513471225716013022 00000000000000/*------------------------------------------------------------------------ * Copyright 2009 (c) Jeff Brown * * This file is part of the ZBar Bar Code Reader. * * The ZBar Bar Code Reader is free software; you can redistribute it * and/or modify it under the terms of the GNU Lesser Public License as * published by the Free Software Foundation; either version 2.1 of * the License, or (at your option) any later version. * * The ZBar Bar Code Reader is distributed in the hope that it will be * useful, but WITHOUT ANY WARRANTY; without even the implied warranty * of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

There are currently 3 mirrors with ZBar: LinuxTV: Cgit GUI interface: https://git.linuxtv.org/zbar.git/ Git tree: git://linuxtv.org/zbar.git https://git.linuxtv.org/cgit.cgi/zbar.git http://git.linuxtv.org/cgit.cgi/zbar.git Github: https://github.com/mchehab/zbar.git Gitlab: https://github.com/mchehab/zbar You can use git clone to get the latest version from any of the above repositories. if you haven't already, grab the ZBar git repository. For example, to get it from Github, use: git clone https://github.com/mchehab/zbar.git cd zbar autoreconf -vfi This will generate ./configure and all that other foo you usually get with a release. you will need to have recent versions of some basic "developer tools" installed in order for this to work, particularly GNU autotools. these versions of autotools are known to work (newer versions should also be fine): GNU autoconf 2.61 GNU automake 1.10.1 GNU libtool 2.2.6 GNU gettext 0.18.1.1 GNU pkg-config 0.25 xmlto 0.0.20-5 (for docs building) all above mentioned tools (except xmlto) must be installed in the same prefix. mixing prefixes (i.g. /usr/bin and /usr/local/bin) may lead to errors in configuration stages Writing descriptions for your patches ===================================== Please add a good description to your patch adding why it is needed, what the patch does and how. This helps us when reviewing your work when you submit upstream. We use a process similar to the Linux Kernel for patch submissions. In particular, submitted patches should have a developer's certificate of origin, as described at: https://linuxtv.org/wiki/index.php/Development:_Submitting_Patches#Developer.27s_Certificate_of_Origin_1.1 In practice, please add: Signed-off-by: your name on your pathes. Submitting patches ================== When you're done hacking, please submit your work back upstream. If you use Github or Gitlab, you can fork ZBar from it, develop your patches and then push again to your clone, asking the patch merge using the GUI. Although we prefer if you submit patches via either Github or Gitlab, you can also submit them via e-mail to: linux-media@vger.kernel.org If you opt to do so, please place [PATCH ZBar] at the subject of your e-mails for us to not mix them with patches for the Kernel or for other media tools. and want to make your patch, run: git diff > hacked.patch Other things for you to read, in order to know more about how to submit your work for upstreaming processes in general, that could be useful for you to prepare yourself on submitting patches to ZBar: - https://linuxtv.org/wiki/index.php/Development:_Submitting_Patches - http://www.faqs.org/docs/artu/ch19s02.html - http://www.catb.org/~esr/faqs/smart-questions.html zbar-0.23/aclocal.m40000664000175000017500000035561513471606245011206 00000000000000# generated automatically by aclocal 1.16.1 -*- Autoconf -*- # Copyright (C) 1996-2018 Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. m4_ifndef([AC_CONFIG_MACRO_DIRS], [m4_defun([_AM_CONFIG_MACRO_DIRS], [])m4_defun([AC_CONFIG_MACRO_DIRS], [_AM_CONFIG_MACRO_DIRS($@)])]) m4_ifndef([AC_AUTOCONF_VERSION], [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.69],, [m4_warning([this file was generated for autoconf 2.69.

The `configure` shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile` in each directory of the package. It may also create one or more `.h` files containing system-dependent definitions. Finally, it creates a shell script `config.status` that you can run in the future to recreate the current configuration, a file `config.cache` that saves the results of its tests to speed up reconfiguring, and a file `config.log` containing compiler output (useful mainly for debugging `configure`). If you need to do unusual things to compile the package, please try to figure out how `configure` could check whether to do them, and mail diffs or instructions to the address given in the `README` so they can be considered for the next release. If at some point `config.cache` contains results you don't want to keep, you may remove or edit it. The file `configure.in` is used to create `configure` by a program called `autoconf`. You only need `configure.in` if you want to change it or regenerate `configure` using a newer version of `autoconf`. The simplest way to compile this package is: 1. `cd` to the directory containing the package's source code and type `autoreconf -vfi && ./configure` to configure the package for your system. If you're using `csh` on an old version of System V, you might need to type `sh ./configure` instead to prevent `csh` from trying to execute `configure` itself. Running `configure` takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make` to compile the package. 3. Optionally, type `make check` to run any self-tests that come with the package. 4. Type `make install` to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean`. To also remove the files that `configure` created (so you can compile the package for a different kind of computer), type `make distclean`. There is also a `make maintainer-clean` target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure` script does not know about. You can give `configure` initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure Or on systems that have the `env` program, you can do it like this: env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make` that supports the `VPATH` variable, such as GNU `make`. `cd` to the directory where you want the object files and executables to go and run the `configure` script. `configure` automatically checks for the source code in the directory that `configure` is in and in `../`. If you have to use a `make` that does not supports the `VPATH` variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean` before reconfiguring for another architecture. Installation Names ================== By default, `make install` will install the package's files in `/usr/local/bin`, `/usr/local/man`, etc. You can specify an installation prefix other than `/usr/local` by giving `configure` the option `--prefix=PATH`. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure` the option `--exec-prefix=PATH`, the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH` to specify different values for particular kinds of files. Run `configure --help` for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure` the option `--program-prefix=PREFIX` or `--program-suffix=SUFFIX`. Optional Features ================= Some packages pay attention to `--enable-FEATURE` options to `configure`, where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE` options, where PACKAGE is something like `gnu-as` or `x` (for the X Window System). The `README` should mention any `--enable-` and `--with-` options that the package recognizes. For packages that use the X Window System, `configure` can usually find the X include and library files automatically, but if it doesn't, you can use the `configure` options `--x-includes=DIR` and `--x-libraries=DIR` to specify their locations. Specifying the System Type ========================== There may be some features `configure` can not figure out automatically, but needs to determine by the type of host the package will run on. Usually `configure` can figure that out, but if it prints a message saying it can not guess the host type, give it the `--host=TYPE` option. TYPE can either be a short name for the system type, such as `sun4`, or a canonical name with three fields: CPU-COMPANY-SYSTEM See the file `config.sub` for the possible values of each field. If `config.sub` isn't included in this package, then this package doesn't need to know the host type. If you are building compiler tools for cross-compiling, you can also use the `--target=TYPE` option to select the type of system they will produce code for and the `--build=TYPE` option to select the type of system on which you are compiling the package. Sharing Defaults ================ If you want to set default values for `configure` scripts to share, you can create a site shell script called `config.site` that gives default values for variables like `CC`, `cache_file`, and `prefix`. `configure` looks for `PREFIX/share/config.site` if it exists, then `PREFIX/etc/config.site` if it exists. Or, you can set the `CONFIG_SITE` environment variable to the location of the site script. A warning: not all `configure` scripts look for a site script. Operation Controls ================== `configure` recognizes the following options to control how it operates. `--cache-file=FILE` Use and save the results of the tests in FILE instead of `./config.cache`. Set FILE to `/dev/null` to disable caching, for debugging `configure`. `--help` Print a summary of the options to `configure`, and exit. `--quiet` `--silent` `-q` Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null` (any error messages will still be shown). `--srcdir=DIR` Look for the package's source code in directory DIR. Usually `configure` can determine that directory automatically. `--version` Print the version of Autoconf used to generate the `configure` script, and exit. `configure` also accepts some other, not widely useful, options. Debian/Ubuntu package build =========================== For Debian/Ubuntu, one alternative way to build ZBar is by using pbuilder. In order to install pbuilder, see, for example: https://wiki.ubuntu.com/PbuilderHowto Once you have pbuilder installed and configured, you can build a ZBar package, running the following commands as root: # pbuilder create --basetgz /var/cache/pbuilder/base-test.tgz # pbuilder build --basetgz /var/cache/pbuilder/base-test.tgz ../zbar_0.20.2.dsc zbar-0.23/zbarimg/0000775000175000017500000000000013471606255011043 500000000000000zbar-0.23/zbarimg/Makefile.am.inc0000664000175000017500000000062613471225716013572 00000000000000bin_PROGRAMS += zbarimg/zbarimg zbarimg_zbarimg_SOURCES = zbarimg/zbarimg.c zbarimg_zbarimg_CPPFLAGS = $(MAGICK_CFLAGS) $(AM_CPPFLAGS) zbarimg_zbarimg_LDADD = $(MAGICK_LIBS) zbar/libzbar.la # automake bug in "monolithic mode"?

It supports EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 93, Code 39, Codabar, Interleaved 2 of 5 and QR Code. Included with the library are basic applications for decoding captured bar code images and using a video device (eg, webcam) as a bar code scanner. For application developers, language bindings are included for C, C++, Python and Perl as well as GUI widgets for Qt, GTK and PyGTK.
