Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, 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 or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's 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 give any other recipients of the Program a copy of this License along with the Program. 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 Program or any portion of it, thus forming a work based on the Program, 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) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, 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 Program, 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 Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) 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; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, 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 executable. However, as a special exception, the source code 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. If distribution of executable or 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 counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program 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. 5. 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 Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program 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 to this License. 7. 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 Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program 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 Program. 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. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program 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. 9. The Free Software Foundation may publish revised and/or new versions of the 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 Program 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 Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, 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 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "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 PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. 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 PROGRAM 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 PROGRAM (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 PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. 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. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program 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 General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. geg-2.0.9/depcomp0000755000175000017500000005601612735031745014056 0ustar georgeskgeorgesk#! /bin/sh # depcomp - compile a program generating dependencies as side-effects scriptversion=2013-05-30.07; # UTC # Copyright (C) 1999-2014 Free Software Foundation, Inc. # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2, or (at your option) # any later version. # This program 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.

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 ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell command `./configure && make && make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the `README' file for instructions specific to this package. Some packages provide this `INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. 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, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. 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 you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You need `configure.ac' 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 `./configure' to configure the package for your system. Running `configure' might take a while. 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, generally using the just-built uninstalled binaries. 4. Type `make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the `make install' phase executed with root privileges. 5. Optionally, type `make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior `make install' required root privileges, verifies that the installation completed correctly. 6. 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. 7. Often, you can also type `make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide `make distcheck', which can by used by developers to test that all other targets like `make install' and `make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. 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 can use 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 `..'. This is known as a "VPATH" build. With a non-GNU `make', it is safer 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. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple `-arch' options to the compiler but only a single `-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the `lipo' tool if you have problems. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' 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. In general, the default for these options is expressed in terms of `${prefix}', so that specifying just `--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to `configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the `make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, `make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of `${prefix}'. Any directories that were specified during `configure', but not in terms of `${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the `DESTDIR' variable. For example, `make install DESTDIR=/alternate/directory' will prepend `/alternate/directory' before all installation names. The approach of `DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of `${prefix}' at `configure' time. Optional Features ================= 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'. 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. Some packages offer the ability to configure how verbose the execution of `make' will be. For these packages, running `./configure --enable-silent-rules' sets the default to minimal output, which can be overridden with `make V=1'; while running `./configure --disable-silent-rules' sets the default to verbose, which can be overridden with `make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. HP-UX `make' updates targets which have the same time stamps as their prerequisites, which makes it generally unusable when shipped generated files such as `configure' are involved. Use GNU `make' instead. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its `' header file. The option `-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put `/usr/ucb' early in your `PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in `/usr/bin'. So, if you need `/usr/ucb' in your `PATH', put it _after_ `/usr/bin'. On Haiku, software installed for all users goes in `/boot/common', not `/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS 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 machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. 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. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for `CONFIG_SHELL' due to an Autoconf limitation. Until the limitation is lifted, you can use this workaround: CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of all of the options to `configure', and exit. `--help=short' `--help=recursive' Print a summary of the options unique to this package's `configure', and exit. The `short' variant lists options used only in the top level, while the `recursive' variant lists options also present in any nested packages. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--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. `--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations. `--no-create' `-n' Run the configure checks, but stop before creating any output files. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. geg-2.0.9/examples/0000755000175000017500000000000012735240064014303 5ustar

I wrote the program for various reasons: - I wanted to learn how to use GTK+. Previously I have always used Motif but when I saw The GIMP, I thought GTK+ looked pretty neat. - I actually thought it might be a useful program :) At the time of authoring I was studying Communication Systems, in which I had to keep trying to visualise what all these FM and AM signals looked like... - I had gotten so much out of Linux and the community that I really wanted to contribute something in return. Geg stores its preferences in $(HOME)/.gegrc. It also parses the file $(HOME)/.gtkrc on startup with gtk_rc_parse() to get GTK+ settings, this can be completely ignored though. Warnings may be given by geg if old configuration files are loaded. These warnings will go away as soon as a new configuration is saved, or the configuration file is deleted. I welcome any feedback: comments, suggestions, bug reports, flames, etc.... If you want to see any particular new features implemented, please email me.

La représentation graphique associée apparaît instantanément dans la fenêtre principale, et peut être exportée aux formats EPS, PDF ou SVG. Plusieurs courbes et fonctions peuvent être tracées sur la même fenêtre graphique. 4 modes sont disponibles : - Cartésien: y=f(x) - Polaire: t→r(t) - Paramétrique: t→(x,y) - Suite: n→u(n) La commutation est faite avec les boutons ad hoc de la barre d'outils, ou en utilisant les fonctions spéciales cart, polar, param, sequ, voir plus loin pour plus de détails. Les symboles x, y désignent les coordonnées du plan, t est utilisé comme variable dans les modes paramétrique et polaire. En polaire, t désigne l'angle en radian, et r est la distance à l'origine, soit r=sqrt(x^2+y^2). En mode suite, n est une valeur entière utilisée comme indice de la suite à représenter. La suite est calculée de la valeur n=nmin à la valeur n=nmax si nmax est spécifié. Les paramètres tmin ou tmax peuvent aussi être utilisés. Sinon, la suite est calculée pour toutes les valeurs de n visibles sur l'écran. L'entrée de texte du bas est utilisée pour saisir la fonction à évaluer ou dessiner. Toutes les variables a-z (sauf e=exp(1)=2.718 ... et les coordonnées x, y, t, r) peuvent être utilisées en tant que paramètres additionnels. Sauf pour e, elles sont préaffectées à 0 au démarrage, et sont gardées inchangées jusqu'à ce qu'elles soient affectées à une autre valeur par une opération ultérieure, ou réinitialisées à 0 par un clic sur le bouton de réinitialisation. Une telle affectation se fait par exemple par g=0.5772156649015328 Plusieurs calculs ou affectations peuvent être effectuées dans une même ligne de commande en les séparant par le symbole ";" , par exemple, en saisissant m=pi/6;x=cos(m*t);y=sin(2*m*t) Toute séquence de calculs peut être sauvegradée dans une "feuille de calculs" sous forme d'un fichier *.geg qui spécifie l'ensemble des paramètres à évaluer et des fonctions à représenter. Ces fichiers peuvent ensuite être réouverts par geg. 2] Liste des fonctions et opérateurs prédéfinis Les fonctions suivantes sont reconnues : sin (sinus) cos (cosinus) tan (tangent) cot (cotangent, également cotan) sec (secant) csc (cosecant) asin (arc-sinus, également arcsin) acos (arc-cosinus, également arccos) atan (arc-tan, également arctan) acot (arc-cotan, également arccot) acsc (arc-cosecant, également acsc) sinc (sinus-cardinal = sin(pi*x)/pi*x) sinh (sinus hyperbolique) cosh (cosinus hyperbolique) tanh (tangente hyperbolique) exp (exponentielle naturelle) log (logarithme base 10) ln (logarithme naturel, base e) floor (partie entière) gamma (fonction Gamma) sqrt (racine carrée) cbrt (racine cubique) abs (valeur absolue) sign (fonction signe) char (fonction caractéristique x>=0) Fonctions et opérateurs spéciaux clip (restriction aux valeurs >=0 de l'argument) cut (restriction aux valeurs >0 de l'argument) cart (passer en mode cartésien) polar (passer en mode polaire) param (passer en mode paramétrique) sequ (passer en mode représentation de suite) ' (opérateur de dérivation d'une fonction) int (opérateur d'intégration) tgt (opérateur de tangente affine) Les constantes suivantes sont reconnues : pi (3.141592653....) e (2.718281828....) (mais e est un paramètre comme les autres et peut être réaffecté à une autre valeur.) Les opérateurs binaires suivants sont reconnus: + (Ajouter) - (Soustraire) * (Multiplier) / (Diviser) ^ (Élever à la puissance) = (Affectation,équations) Les symboles divers suivants sont reconnus: ( (parenthèse gauche) ) (parenthèse droite) [ (crochet gauche) ] (crochet droit) { (accolade gauche) } (accolade droite) a-z (paramètres/variables) 3] Caractères spéciaux, directives Ces modes ne produisent aucun tracé graphique et sont destinés à effecter des calculs ou à initialiser des paramètres. a] Mode évaluation (?) Le mode évaluation est activé en commençant la ligne de commande par le caractère ?. De cette manère, geg peut être utilisé comme une calculatrice numérique. La précision est celle du type C "double", soit environ 15-16 chiffres significatifs. Ainsi ?a=3,7;b=-1.2;a^b va afficher: = 0.208045310600227 b] Résolution d'équations (=) Toute entrée de la forme "=f(x)" initie un calcul des racines de f(x)=0 par un procédé de dichotomie, en restriction à l'intervalle réel tmin < x < tmax, ou xmin < x < xmax si tmin, tmax ne sont pas spécifiés. Les boutons de souris peuvent également être utilisés sur la fenêtre graphique pour effectuer des résolutions d'équations dans la zone sélectionnée. Voici les actions possibles des boutons : - Bouton gauche : sélection de la zone à zoomer - Bouton du milieu : trouver les intersections f(x)=g(x) - Bouton droit : résoudre f(x)=0 c] Définition de paramètres ou de fonctions (&) Le caractère initial & est utilisé pour introduire la définition de paramètres ou de fonctions. Par exemple &c=2.31*sin(pi/7) affecte la valeur spécifiée à la variable c. Les paramètres tmin, tmax, amin, amax (bornes pour t, et pour l'angle polaire, respectivement) sont également assignables, par exemple via &amax=7*pi Les chaînes de caractères à 2 lettres lettres fa ... fz sont réservées pour la définition de fonctions utilisateur. Ces fonctions peuvent être appelées plus tard, à partir de la feuille de calcul, exactement comme les fonctions prédéfinies. La syntaxe pour définir une nouvelle fonction fc(p) de la variable p utilise aussi & comme marqueur initial : on peut définir par exemple &fc(p)=sin(p*p) Les variables a-z peut être indifféremment utilisées dans la définition des fonctions, et celle-ci peut inclure d'autres paramètres (éviter tout de même les variables x, y, r, t qui sont réservées aux coordonnées). Au moment de l'appel de telles fonctions, les paramètres doivent avoir été préalablement initialisés à une valeur (sinon le résultat sera indéfini). Une seule définition de fonction est permise par ligne de calculs. Si la fonction ff a déjà été définie, &fg=ff' introduit fg comme étant la dérivée de ff. Deux autres constructions apparentées sont &fs=int_c_ff &ft=tgt_c_ff Ceci définit fs(x) comme étant l'intégrale indéfinie de ff s'annulant en c (intégrale de ff prise entre c et x), et ft comme étant la fonction linéaire affine qui représente la tangente à y = ff (x) au point x=c, à savoir ft(x)=ff'(c)(x-c) + ff(c) c est utilisé ici comme paramètre formel qui doit être préalablement spécifié pour pouvoir tracer la primitive, respectivement la tangente, par exemple en saisissant &c=0; fs(x) &c=2*pi ft(x) Les paramètres spéciaux der_step, et tgt_right, tgt_left sont respectivement le pas (relatif) utilisé pour calculer la différentiation numérique (0.001 par défaut), le la taille relative du segment de tangente à tracer sur la droite et sur la gauche (la valeur par défaut est 100 qui donne une demi-tangente infinie sur le côté correspondant). Enfin int_step est le pas absolu utilisé pour l'intégration numérique (0.005 par défaut). On peut par exemple saisir &der_step=0.003 &int_step=0.002 &tgt_left=0;tgt_right=100 La dernière ligne correspond au choix d'une demi-tangente infinie sur la droite. Le paramètre 'gap' est utilisé pour détecter les singularités et discontinuités. La valeur par défaut est &gap=1.0 Des valeurs plus petites de 'gap' augmentent la sensibilité de la détection, mais peuvent conduire à ce que des parties de graphe soient perdues autour des discontinuités. d] Couleurs et épaisseur de ligne des courbes Les directives &lw=0.35 &color=127096008 qui peuvent être également être concaténées avec le caractère ; comme suit : &lw=0.35;color=127096008 spécifient une épaisseur de ligne égal à 0.35 et une couleur RVB avec rouge=127/255, vert=96/255, bleu=8/255. Ces paramètres s'appliquent aux courbes qui sont tracées ensuite, jusqu'à ce que de nouvelles valeurs des paramètres soient définies. Les paramètres lw et color sont considérés comme non spécifiés si on leur donne des valeurs négatives, par exemple -1. Dans ce cas geg utilise les valeur de lw globale par défault (lw=0.5) et la palette de couleurs par défaut en fonction du numéro de la courbe. La couleur et l'épaisseur de ligne des axes, ainsi que la couleur des valeurs numériques de x, y, t peuvent être spécifiées grâce au menu "Préférences". e] Suites Le 'mode suite' eut être activé grâce à la directive &sequ Dans ce contexte, le paramètre spécial 'ptrad' spécifie le rayon des points représentant les valeurs (n,u(n)) de la suite. Ce paramètre est affecté en posant par exemple &ptrad=2 Les paramètres nmin et nmax peuvent être affectés pour spécifier l'intervalle de calcul de la suite : &nmin=3 f] Commentaires Toute chaîne de caractères commençant par # est considérée comme un commentaire. Une telle chaîne est reproduite à l'identique dans la feuille de calculs, sans induire quelque action que ce soit. Les lignes blanches peuvent être créees en saisissant la chaîne de 2 caractères "##". 4] Expressions symboliques formelles de geg La notation étendue "Backus Naur" (EBNF) utilisée dans geg est: :: = [ + | - ] { + | - } :: = { * | / | ^ } :: = | | () :: = | e pi | a-z :: = (); geg-2.0.9/help/help.en0000644000175000017500000002123012715701045014666 0ustar georgeskgeorgeskGEG is a numerical and graphing calculator. 1] Main features Geg's main purpose is to draw 2D curves defined by mathematical functions. The actual drawing appears instantly in the main graphic window, and can be exported to EPS, PDF or SVG formats. Several curves and functions can be drawn on the same graphic window. There are 4 modes: - cartesian : y = f(x) - polar: t→r(t) - parametric: t→(x,y) - sequence: n→u(n) The switch is made with the ad hoc toolbar buttons or by using the cart, polar, param, sequ special functions, see below for more details. The symbols x, y denote the plane coordinates, and t is used as the variable in the parametric and polar modes. In polar mode, t is the angle in radian, and r is the distance to origin, namely r=sqrt(x^2+y^2). In sequence mode, n is an integer and represents the index of the sequence. The sequence if computed from n=nmin to n=nmax if nmax is specified, or within the limits of the drawing otherwise. The parameters tmin, tmax can alternatively be used for the same purpose. The bottom text entry is used to specify any function to be evaluated or drawn. All variables a-z (except e=exp(1)=2.718... and the coordinates x, y, t, r) can be used as extra parameters. Except for e, they are initially set to NAN ("not a number", undefined value) at startup, and are kept unchanged until they are assigned another value by some further operation, or the user clicks the reinitialization button. Such an assignment is done e.g. by g=0.5772156649015328 Several calculations or assignments can be done in order by separating them with ; e.g. by putting on a single line m=pi/6;x=cos(m*t);y=sin(2*m*t) Each drawing can be saved in a "calculation sheet" in the form of a *.geg file that specifies the list of parameters to evaluate and functions to represent. These files can later be reopened by geg. 2] List of predefined functions and operators The following functions are recognised: sin (Sine) cos (Cosine) tan (Tangent) cot (Cotangent, also cotan) sec (Secant) csc (Cosecant) asin (Arc-Sine, also arcsin) acos (Arc-Cosine, also arccos) atan (Arc-Tan, also arctan) acot (Arc-Cotan, also arccot) acsc (Arc-Cosecant, also acsc) sinc (Sine-Cardinal = sin(pi*x)/pi*x) sinh (Hyperbolic Sine) cosh (Hyperbolic Cosine) tanh (Hyperbolic Tangent) exp (Natural exponential) log (log base 10) ln (Natural Log, Log base e) floor (Integer part of real number) gamma (Gamma function) sqrt (Square Root) cbrt (Cube Root) abs (Absolute Value) sign (Sign function) char (Characteristic function x>=0) Special functions and operators clip (Restriction to >=0 values of argument) cut (Restriction to >0 values of argument) cart (Set cartesian mode) polar (Set polar mode) param (Set parametric mode) sequ (Set sequence mode) ' (Derivation operator) int (Integration operator) tgt (Affine tangent operator) The following constants are recognised: pi (3.141592653....) e (2.718281828....) (but e can viewed as a parameter and can be reset). The following binary operators are recognised: + (Add) - (Subtract) * (Multiply) / (Divide) ^ (Raise to the Power) = (Assignment,Equations) The following miscellaneous symbols are recognised: ( (Left Bracket) ) (Right Bracket) [ (Left Square Bracket) ] (Right Square Bracket) { (Left Curly Bracket) } (Right Curly Bracket) a-z (Variable Parameters) 3] Escape characters, directives These modes do not produce any graphical output, but allow some calculations or definitions to be made. a] Evaluation mode (?) Evaluation is turned on (and drawing disabled) by starting the command line with ?. In this way, geg can be used as a basic calculator. The accuracy corresponds to the C-type "double" , that is approximately 16 significant digits. For example ?a=3.7;b=-1.2;a^b will output: = 0.208045310600227 b] Solutions of equations (=) Any input of the form "=f(x)" initiates a calculation of the roots of f(x)=0 by a dichotomy method, within the interval tmin < x < tmax, or xmin < x < xmax if tmin, tmax are not specified. Alternatively, mouse Buttons can be used on the graphic window to select a rectangle and launch equation resolutions in the corresponding area. Here are the various actions of buttons: - Left button: zoom to selected area - Middle button: find intersections f(x)=g(x) - Right button: solve f(x)=0 c] Definitions of parameters or functions (&) The initial character & is used to define parameters or functions. For instance &c=2.31*sin(pi/7) assigns the specified value to variable c. Other assignable parameters include tmin, tmax, amin, amax (ranges for t, and polar angle, respectively), e.g. via &amax=7*pi The special 2 letter strings fa ... fz are meant to be used as user defined functions. Such functions can then be called later from the calculation sheet, exactly as the predefined functions. The syntax to define a new function fc(p) of the variable p uses & as the initial marker: one can set e.g. &fc(p)=sin(p*p) Any variable a-z can be used in a function definition, and that definition may include other parameters (preferably not x, y, r, t which will probably vary according to the choice of coordinates), provided they are previously initialized to a value (otherwise the result will be undefined). A function definition should be isolated on its line. If the function ff has already been defined, then &fg=ff' will let fg be the derivative of ff. Two related constructions are &fs=int_c_ff &ft=tgt_c_ff This defines fs(x) to be the indefinite integral of ff navishing at c (i.e. the integral of ff taken between c and x), and ft to be the affine linear function that represents the tangent to y=ff(x) at point x=c, namely ft(x)=ff'(c)(x-c) + ff(c) c is used here as a formal parameter that has to be set prior to actually draw the primitive function, respectively the tangent function, e.g. by putting &c=0; fs(x) &c=2*pi ft(x) The special parmeters der_step, tgt_right, tgt_left are respectively the relative step used to perform numerical differentiation (0.001 by default), the relative size of the tangential segment to be drawn on the right side and on the left side (default value is 100 which yields an infinite tangent half-line on the corresponding side). Finally, int_step is the absolute value of the integration step (0.005 by default). One can e.g. set &der_step=0.003 &int_step=0.002 &tgt_left=0;tgt_right=100 The last setting corresponds to an infinite right half-tangent. The gap parameter is used to detect singularities and discontinuities. The default value is &gap=1.0 Smaller values of the gap increase sensitivity but may lead to losing parts of the graph around the points of discontinuity. d] Linewidth and color of curves The directives &lw=0.35 &color=127096008 which can be concatened with the character ; in between &lw=0.35;color=127096008 specify a linewidth equal to 0.35 and a RGB color with red=127/255, green=96/255, blue=8/255. They apply for the curves that are subsequently drawn, until new values of those parameters are set. The lw and color parameters are considered unspecified if they are given negative values, e.g. -1. In that case geg uses the global default value lw=0.5 and the default color scheme according to the index of the curve. The color and linewidth of the axes, and the color of the numerical values of x, y, t can be specified from the "Preferences" dialog. e] Sequences The "sequence mode" can be started via the directive &sequ In this setting, the special parameter 'ptrad' indicates the radius of points representing the values (n,u(n)) of the sequence. The parameter is set by putting e.g. &ptrad=2 The parameters nmin and nmax can be used to specify the interval in which the sequence is to be computed: &nmin=3 f] Comments Any string starting by # is a comment. Such a string is reproduced verbatim in the calculation sheet without generating any action. Blank lines can be entered by a 2 character string ##. 4] Formal symbolic expressions in geg The Extended Backus Naur Notation (EBNF) used in geg is: ::= [ + | - ] { + | - } ::= { * | / | ^ } ::= | | () ::= | e pi | a-z ::= (); geg-2.0.9/desktop/0000755000175000017500000000000012735240064014136 5ustar georgeskgeorgeskgeg-2.0.9/desktop/Makefile.am0000644000175000017500000000045012712723600016166 0ustar georgeskgeorgeskall: geg.desktop plot2d.svg install: mkdir -p $(DESTDIR)/usr/share/applications install -c -m 644 geg.desktop $(DESTDIR)/usr/share/applications mkdir -p $(DESTDIR)/usr/share/pixmaps install -c -m 644 plot2d.svg $(DESTDIR)/usr/share/pixmaps distclean: clean rm -f Makefile clean: rm -f *~ geg-2.0.9/desktop/plot2d.svg0000644000175000017500000001236012712723445016071 0ustar georgeskgeorgesk geg-2.0.9/desktop/graph_icon.png0000644000175000017500000007563712674176204017005 0ustar georgeskgeorgeskPNG  IHDR) AiCCPICC ProfileH wTSϽ7" %z ;HQIP&vDF)VdTG"cE b PQDE݌k 5ޚYg}׺PtX4X\XffGD=HƳ.d,P&s"7C$ E6<~&S2)212 "įl+ɘ&Y4Pޚ%ᣌ\%g|eTI(L0_&l2E9r9hxgIbטifSb1+MxL 0oE%YmhYh~S=zU&ϞAYl/$ZUm@O ޜl^ ' lsk.+7oʿ9V;?#I3eE妧KD d9i,UQ h A1vjpԁzN6p\W p G@ K0ށiABZyCAP8C@&*CP=#t] 4}a ٰ;GDxJ>,_“@FXDBX$!k"EHqaYbVabJ0՘cVL6f3bձX'?v 6-V``[a;p~\2n5׌ &x*sb|! ߏƿ' Zk! $l$T4QOt"y\b)AI&NI$R$)TIj"]&=&!:dGrY@^O$ _%?P(&OJEBN9J@y@yCR nXZOD}J}/G3ɭk{%Oחw_.'_!JQ@SVF=IEbbbb5Q%O@%!BӥyҸM:e0G7ӓ e%e[(R0`3R46i^)*n*|"fLUo՝mO0j&jajj.ϧwϝ_4갺zj=U45nɚ4ǴhZ ZZ^0Tf%9->ݫ=cXgN].[7A\SwBOK/X/_Q>QG[ `Aaac#*Z;8cq>[&IIMST`ϴ kh&45ǢYYF֠9<|y+ =X_,,S-,Y)YXmĚk]c}džjcΦ浭-v};]N"&1=xtv(}'{'IߝY) Σ -rqr.d._xpUەZM׍vm=+KGǔ ^WWbj>:>>>v}/avO8 FV> 2 u/_$\BCv< 5 ]s.,4&yUx~xw-bEDCĻHGKwFGEGME{EEKX,YFZ ={$vrK .3\rϮ_Yq*©L_wד+]eD]cIIIOAu_䩔)3ѩiB%a+]3='/40CiU@ёL(sYfLH$%Y jgGeQn~5f5wugv5k֮\۹Nw]m mHFˍenQQ`hBBQ-[lllfjۗ"^bO%ܒY}WwvwXbY^Ю]WVa[q`id2JjGէ{׿m>PkAma꺿g_DHGGu;776ƱqoC{P38!9 ҝˁ^r۽Ug9];}}_~imp㭎}]/}.{^=}^?z8hc' O*?f`ϳgC/Oϩ+FFGGόzˌㅿ)ѫ~wgbk?Jި9mdwi獵ޫ?cǑOO?w| x&mf2:Y~ pHYs  &iTXtXML:com.adobe.xmp 2013-04-02T21:04:68 Pixelmator 2.1.4 1 72 5 1 72 600 1 600 xW`@IDATx ]UP 2$!aJdZ"sk_}v8 ($L$! 2h$y U_nVs={is~u=g}ꬳ^{L\&Ʒ90}  1'y՟?o>/G;~߳rR!.G99ߜz͵iQT% !QV(Y Gۑ7#S:#ސ?^܋E>X?c 益-_G*#_+}umsSɷ̿r]|*99|<(Gs`ӦM{t 78Q-5jȡCs7Q)c1"̇!ʟA|*'ăիVt̙ ĕ?
