In other projects, it is set to # '$srcdir', '$srcdir/..', or '$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is '.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

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.

Scope This document includes information about the GNU-Linux/Unix version of Alien Arena. Custom options and other information specific to Alien Arena are included here. For general information, licensing, and contributers, see the README.txt and license.txt documents (in the docs/ subdirectory in the distribution archive). For generic information about installation, see the GNU INSTALL document. 2. Version 7.66 - For Players The performance of Alien Arena 7.66 is much better that previous versions. Recent desktop and notebook computers with 3D acceleration for OpenGL will perform well. Use the Video Settings menu to override the automatically selected performance level. Alien Arena installation alternatives: * Your distribution's package manager. * PlayDeb or Desura distribution service. PlayDeb is at http://www.playdeb.net/. Desura is at http://www.desura.com/. * Build from source. See the "Installation from Distribution Archive" section below. For more detail see these sections * Help and Support * Configuration and Troubleshooting * Network Information * Running the Program 3. Version 7.66 - For Packagers * The incompatibility with ODE 0.12 has been corrected. The configure option to use the system libode is --with-system-libode. If the system libode causes problems with ragdoll animation, configure the program to use the integrated libode. * There is now direct dependency on zlib. The configure option --with-zlib should be used. * The configure.ac status report has more information. * Some little used options have been removed from configure.ac * The documentation installation override configure option should work now. The configure option is --disable-documents. * --with-xf86vm is the default. * --without-xf86dga is the default. * The Autotools build used autoconf 2.68, and automake 1.11.6. The default standard install follows this file system scheme: * ${bindir}/alienarena (the client program) * ${bindir}/alienarena-ded (the dedicated server program) * ${pkgdatadir}/arena/ (read only configuration files) * ${pkgdatadir}/botinfo/ (read only bot control files) * ${pkgdatadir}/data1/ (read only resource files) * ${datadir}/icons/alienarena.png (the official icon) The configure option is --with-icondir=DIR * ${docdir}/ (documents, licenses) The shared directory is defined at build time to be exactly $(pkgdatadir). The preprocessor symbol, DATADIR, is set to $(pkgdatadir), The program expects the arena, botinfo, and data1 shared, read-only subdirectories to be there. The program defaults for the user's home directory are: * ${HOME}/.codered/arena/ (read/write configuration and resource files) * ${HOME}/.codered/botinfo/ (read/write bot control files) * ${HOME}/.codered/data1/ (read/write resource files, rarely created) At build time, the environment variable, ALIENARENA_HOMEDIR, can be used to override the default .codered user home subdirectory. At run time, the environment variable, COR_GAME, will override the user home subdirectory program setting. This should normally be left as a user option. The arena subdirectory in the user home directory receives most of automatic resource downloads. By convention, it is where 3rd party maps are placed. The files in the user home have priority over the same name files in the read-only, shared directories. 4. Help and Support The Alien Arena Home Page URL is: http://red.planetarena.org/ There are links there to the Alien Arena Forum and other helpful Internet resources. The Alien Arena IRC (Internet Relay Chat) channel is now served by: irc.planetarena.org The in-game IRC connects to #alienarena there. There are web sites with 3rd party maps, skins, etc. See the Home Page for links. There is a Subversion (SVN) repository for Alien Arena. See the topic "Getting Alien Arena from SVN" below. Alien Arena is on IndieDB. http://www.indiedb.com/games/alien-arena-2008 Alien Arena is on Facebook and Twitter. See the Homepage for links. 5. Network Information These ports are used by the program: * UDP 27900 for the master server. Used for getting server list. * UDP 27901 for the client. * UDP 27902 for account/stats system password validation. * UDP 27910 is the default for a server, but is often configured otherwise. * TCP 6667 is the default for in-game connection to the IRC channel. The cURL library is used to retrieve game resources, player ranking information, and current version information from these URLs: * http://red.planetarena.org/sv_downloadurl * http://stats.planetarena.org/playerrank.db * http://red.planetarena.org/version/crx_version Online performance will vary depending on the network connection between the your computer (the client) and the server. Servers with *lower* ping are better. Playing online may require firewall configuration. 6. Installation from Distribution Archive This describes the standard installation. There is another installation method described below in section, "Alternate Install". If you are reading this, you may have already unpacked the distribution archive (aka, "tarball") into your HOME directory. Otherwise, the terminal command line for unpacking the archive is: $ tar -xzf alienarena-.tar.gz Or, using the graphical file browser, right click on the file name, and left click on "Extract Here." Then follow the instructions below to build the program. To build Alien Arena requires the compiler and various libraries. If you have built other programs these will probably be installed. If they are not there will be errors and the configure procedure will fail. If it fails, check the error messages for required software packages that may be missing. Check the forum for easy ways to install the required libraries for the operating system you are using. Alien Arena uses these components (in parentheses: some example file name variations): *X11 (libx11-dev, libX11, libxxf86dga-dev, libxxf86vm-dev, libXxf86vm) *OpenGL (libgl1-mesa-dev, libGL) *OpenAL 1.1 (libopenal, libopenal-dev) *Ogg-Vorbis, (libogg-dev, libvorbis-dev. libogg, libvorbis, libvorbisfile) *cURL, (libcurl, libcurl4-gnutls-dev) *FreeType2 (libfreetype, libfreetype6-dev) *JPEG (libjpeg8-dev) *ZLib (libz) *ODE (libode, libode-dev) Using the terminal, change to the "alienarena-7.66" directory and enter these commands: --- Simple Version --- $ ./configure $ make $ sudo make install --- Not-so-Simple Version --- In the following the command options are listed on separate lines with short explanations. They are entered on one line with the command, of course. $ export CFLAGS= -O3 (more optimization than -O2) -pipe (faster compile) --march=native (tuned for CPU on this machine) -DNDEBUG (remove assert statements) -Wp,-D_FORTIFY_SOURCE=2 (improved security) -fstack-protector --param=ssp-buffer-size=4 (improved security) If not configuring with the --with-system-libode option then set the same options for the c++ compiler: $ export CXXLAGS= -O3 -pipe --march=native -DNDEBUG -Wp,-D_FORTIFY_SOURCE=2 -fstack-protector --param=ssp-buffer-size=4 $./configure --with-system-libode (use the system libode) --disable-silent-rules (verbose output) --disable-dependency-tracking (speed up one-time build) ALIENARENA_HOMEDIR=some_other_dir (override default ~/.codered) $ make $ sudo make install The variable, ALIENARENA_HOMEDIR, is relative to the user home, NOT the full path. For example: $ ./configure ALIENARENA_HOMEDIR=my_alienarena Check the notes about using the system libode in the "Custom Configure Options" section, if ragdolls do not work right, or if enabling ragdolls crashes the program. By default, 'sudo make install' will install the game programs and data like this: /usr/local/ bin/ alienarena alienarena-ded (dedicated server) share/ alienarena/ arena/ botinfo/ data1/ doc/ alienarena/ icons/ alienarena.png Following installation, intermediate files generated by the build may be removed using: $ make clean To uninstall the program and data that 'sudo make install' installed, run: $ sudo make uninstall The uninstall procedure may not remove all files and directories. Some manual removal may be required. 7. Running the Program To run: $ alienarena In the menu, Single Player will run a simple pre-configured local game. For more single player options, go to the Host Server menu. Setting "public server" to "no" will keep your local game from being broadcast with the master server list. For multiplayer, online play, first enter your player name and a password in the Player Setup menu. Then go to the Join Server menu to find a Server. Bots will always show ping of 0. They have some mean sounding, but amusing, taunts. Do not let it bother you, just frag 'em. They may attack with the "probe", if you let them get close, watch out! Command line options to alienarena are NOT standard. They follow a format inherited from Alien Arena's Quake 2 roots. Command line options are the same as console commands, normally using a '+' character prefix. The details are beyond the scope of this document; but a simple example is: $ alienarena +set maxclients 10 When the program is run, a directory is created in the user HOME directory. Various kinds of data (config files, downloaded data, custom bot setups) are written there. The default directory name is ".codered/". That can be changed using an environment variable, COR_GAME. For example: $ export COR_GAME=/home/user/.my_codered 8. Configuration and Troubleshooting When the game program exits, it stores settings in "config.cfg". The default location for this file is "/home//.codered/arena/", but it might be elsewhere depending on your distribution or configuration. For custom settings, create a file, "autoexec.cfg" in the same directory as "config.cfg". Settings in "autoexec.cfg" will override settings in "config.cfg". Details about settings are beyond the scope of this document. Go to the websites, the forum and the IRC channel for more information. If there are problems, sometimes it helps to delete "config.cfg", and then re-enter menu settings. Alien Arena is based on Quake games. Many of the cvars are the same as Quake 2. More information can be found on the Forum and on the Web. Version 7.66 adds new console variables related to new features. The important ones are set using the menu. Check the forum for more info. Or ask the friendly people in the IRC channel. If the game does not run smoothly, graphics settings may need to be adjusted. It is best to start with the video card's setup utility, then adjust the Alien Arena settings. A different or updated video driver may be needed. There are settings in both the "Game Options" and "Video Options" sections that affect performance. Enable the video frame rate display in the "Game Options" menu by setting "display fps" to yes. The maximum frame rate is set with the console variable ("cvar"), "cl_maxfps". Get more information on the Forum, Websites, and IRC channel. For sound problems, check OpenAL documentation about configuration settings in the "alsoftrc" file. If you have a high resolution mouse, you may need to set the mouse sensitivity cvar. The cvar name is "sensitivity" and it may be set to fractional values between 0.0 and 1.0. Use the console to determine the value, then put it in autoexec.cfg. The mouse may behave badly (always pointing up, for instance). This can usually be fixed by setting the console variable (cvar), "in_dgamouse", to zero. Put this line into the "autoexec.cfg" file: set in_dgamouse "0" By default, the program is built without DGA, so this only applies if the following configure option was set. --with-xf86dga If the display will not go into full screen mode, it is likely the Xxf86vm library (libxxf86vm-dev or libXxf86vm) is missing on your system. 9. Custom Configure Options Run './configure --help' for a list of options. Note that many of the options are built-in and some are not meaningful or useful for Alien Arena. Options are entered on the command line in the usual way; the help output has the details. Refer to the GNU INSTALL document for general details. To build the dedicated server only, use the following configure option: --disable-client By default, configure produces a status message giving information on the configuration. To hide that message, use: --disable-build-status To rename the programs, use the standard configure option. For example: --program-transform-name='s/alienarena/alien-arena/' To install to a different location, use the standard configure option. For example: --prefix=/usr/local/games To specify an installation location for the icon, use the following option. --with-icondir=DIR To use the system-supplied libode, rather than the integrated ODE, use this option: --with-system-libode If 'pkg-config --cflags ode' returns -DdDOUBLE, it is probably safe to use the system library. The integrated ODE is built using these compile options: * -DdDOUBLE * -DdTRIMESH_ENABLED * -DdTRIMESH_OPCODE * -DNDEBUG and -DdNODEBUG Using a libode built with -DdSINGLE makes ragdolls excessively "raggedy". Other libode build variations will likely result in program failure. To disable installation of documents, use the following option. --disable-documents The server terminal will output color if the following option is used. This converts Quake-style color codes to ANSI color escapes. --enable-ansi-color Other Alien Arena custom options are intended mostly for developer use. If you use them, it is assumed that you know what you are doing. 10. Tools Tools/fuse.tar.gz contains a game server browser. See documents in that package for details. Tools/LinuxScripts contains tools for server management. See the README there for details. 11. Alternate Install This configures the installation to use the "traditional", single directory, in-place install. It does not define DATADIR, and the executables need to be in the top game directory. Normally, this install would be done somewhere in your HOME directory. Root privileges would not be required to write the game data. The configure option for renaming of the executables is not supported. If you are a map-builder, you should use this option. Some mapping tools may not work with the "standard" install. If you regularly update to the latest development code from the Subversion Repository, you may prefer this option. The two install methods are not mutually exclusive. With some care, it is possible to use both. The configure option is: --enable-alternate-install Following the usual 'make', it requires $ make install-alternate This just copies the executables to the top game directory. The effect of using any other 'install' make target is "undefined". 12. Getting Alien Arena from SVN The repository has the latest development version of Alien Arena. It contains tools and other resources that are not a part of the regular distribution. The SVN repository may be browsed at: http://svn.icculus.org/alienarena/trunk/ Anonymous read-only checkout is available using this command: svn co svn://svn.icculus.org/alienarena/trunk alienarena More information about Subversion may be found at: http://subversion.apache.org/ alien-arena-7.66+dfsg/COPYING0000600000175000017500000004325412161402016014653 0ustar zero79zero79 GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free 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. 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 Lesser 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 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) 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., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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) year 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 Lesser General Public License instead of this License. alien-arena-7.66+dfsg/game_data.am0000600000175000017500000045524012204314303016042 0ustar zero79zero79# include this file in the top level Makefile.am # # Copyright (C) 2010 COR Entertainment, LLC # # 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., # 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. # # ------------------------------------------------------------- # Note: the GPL applies to this file, but not the files listed. # See license.txt for details, which states, in part: # "It is only permissible to distribute the game data(models, # maps, textures, sound, etc) as a whole, and with the # intention of being used with Alien Arena.

Between AC_INIT and the first command to AC_REQUIRE this macro # you can set the two variables to something explicit instead.

It # sets the PTHREAD_LIBS output variable to the threads library and linker # flags, and the PTHREAD_CFLAGS output variable to any special C compiler # flags that are needed. (The user can also force certain compiler # flags/libs to be tested by setting these environment variables.) # # Also sets PTHREAD_CC to any special C compiler that is needed for # multi-threaded programs (defaults to the value of CC otherwise). (This # is necessary on AIX to use the special cc_r compiler alias.) # # NOTE: You are assumed to not only compile your program with these flags, # but also link it with them as well. e.g. you should link with # $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS # # If you are only building threads programs, you may wish to use these # variables in your default LIBS, CFLAGS, and CC: # # LIBS="$PTHREAD_LIBS $LIBS" # CFLAGS="$CFLAGS $PTHREAD_CFLAGS" # CC="$PTHREAD_CC" # # In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant # has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name # (e.g. PTHREAD_CREATE_UNDETACHED on AIX). # # Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the # PTHREAD_PRIO_INHERIT symbol is defined when compiling with # PTHREAD_CFLAGS. # # ACTION-IF-FOUND is a list of shell commands to run if a threads library # is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it # is not found. If ACTION-IF-FOUND is not specified, the default action # will define HAVE_PTHREAD. # # Please let the authors know if this macro fails on any platform, or if # you have any other suggestions or comments. This macro was based on work # by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help # from M. Frigo), as well as ac_pthread and hb_pthread macros posted by # Alejandro Forero Cuervo to the autoconf macro repository. We are also # grateful for the helpful feedback of numerous users. # # Updated for Autoconf 2.68 by Daniel Richard G. # # LICENSE # # Copyright (c) 2008 Steven G.

Here's ## why we pick this rather obscure method: ## - Don't want to use -MD because we'd like the dependencies to end ## up in a subdir. Having to rename by hand is ugly. ## (We might end up doing this anyway to support other compilers.) ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like ## -MM, not -M (despite what the docs say). Also, it might not be ## supported by the other compilers which use the 'gcc' depmode. ## - Using -M directly means running the compiler twice (even worse ## than renaming). if test -z "$gccflag"; then gccflag=-MD, fi "$@" -Wp,"$gccflag$tmpdepfile" stat=$? if test $stat -ne 0; then rm -f "$tmpdepfile" exit $stat fi rm -f "$depfile" echo "$object : \\" > "$depfile" # The second -e expression handles DOS-style file names with drive # letters. sed -e 's/^[^:]*: / /' \ -e 's/^['$alpha']:\/[^:]*: / /' < "$tmpdepfile" >> "$depfile" ## This next piece of magic avoids the "deleted header file" problem. ## The problem is that when a header file which appears in a .P file ## is deleted, the dependency causes make to die (because there is ## typically no way to rebuild the header). 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.

These include: * * * \li dParamLoStop Low stop angle or position. Setting this to * -dInfinity (the default value) turns off the low stop. * For rotational joints, this stop must be greater than -pi to be * effective. * \li dParamHiStop High stop angle or position. Setting this to * dInfinity (the default value) turns off the high stop. * For rotational joints, this stop must be less than pi to be * effective. * If the high stop is less than the low stop then both stops will * be ineffective. * \li dParamVel Desired motor velocity (this will be an angular or * linear velocity). * \li dParamFMax The maximum force or torque that the motor will use to * achieve the desired velocity. * This must always be greater than or equal to zero. * Setting this to zero (the default value) turns off the motor. * \li dParamFudgeFactor The current joint stop/motor implementation has * a small problem: * when the joint is at one stop and the motor is set to move it away * from the stop, too much force may be applied for one time step, * causing a ``jumping'' motion. * This fudge factor is used to scale this excess force. * It should have a value between zero and one (the default value). * If the jumping motion is too visible in a joint, the value can be * reduced. * Making this value too small can prevent the motor from being able to * move the joint away from a stop. * \li dParamBounce The bouncyness of the stops. * This is a restitution parameter in the range 0..1. * 0 means the stops are not bouncy at all, 1 means maximum bouncyness. * \li dParamCFM The constraint force mixing (CFM) value used when not * at a stop. * \li dParamStopERP The error reduction parameter (ERP) used by the * stops. * \li dParamStopCFM The constraint force mixing (CFM) value used by the * stops. Together with the ERP value this can be used to get spongy or * soft stops. * Note that this is intended for unpowered joints, it does not really * work as expected when a powered joint reaches its limit. * \li dParamSuspensionERP Suspension error reduction parameter (ERP). * Currently this is only implemented on the hinge-2 joint. * \li dParamSuspensionCFM Suspension constraint force mixing (CFM) value. * Currently this is only implemented on the hinge-2 joint. * * If a particular parameter is not implemented by a given joint, setting it * will have no effect. * These parameter names can be optionally followed by a digit (2 or 3) * to indicate the second or third set of parameters, e.g. for the second axis * in a hinge-2 joint, or the third axis in an AMotor joint. */ /** * @brief Create a new joint of the ball type. * @ingroup joints * @remarks * The joint is initially in "limbo" (i.e. it has no effect on the simulation) * because it does not connect to any bodies. * @param dJointGroupID set to 0 to allocate the joint normally. * If it is nonzero the joint is allocated in the given joint group. */ ODE_API dJointID dJointCreateBall (dWorldID, dJointGroupID); /** * @brief Create a new joint of the hinge type. * @ingroup joints * @param dJointGroupID set to 0 to allocate the joint normally. * If it is nonzero the joint is allocated in the given joint group. */ ODE_API dJointID dJointCreateHinge (dWorldID, dJointGroupID); /** * @brief Create a new joint of the slider type. * @ingroup joints * @param dJointGroupID set to 0 to allocate the joint normally. * If it is nonzero the joint is allocated in the given joint group. */ ODE_API dJointID dJointCreateSlider (dWorldID, dJointGroupID); /** * @brief Create a new joint of the contact type. * @ingroup joints * @param dJointGroupID set to 0 to allocate the joint normally. * If it is nonzero the joint is allocated in the given joint group. */ ODE_API dJointID dJointCreateContact (dWorldID, dJointGroupID, const dContact *); /** * @brief Create a new joint of the hinge2 type. * @ingroup joints * @param dJointGroupID set to 0 to allocate the joint normally. * If it is nonzero the joint is allocated in the given joint group. */ ODE_API dJointID dJointCreateHinge2 (dWorldID, dJointGroupID); /** * @brief Create a new joint of the universal type. * @ingroup joints * @param dJointGroupID set to 0 to allocate the joint normally. * If it is nonzero the joint is allocated in the given joint group. */ ODE_API dJointID dJointCreateUniversal (dWorldID, dJointGroupID); /** * @brief Create a new joint of the PR (Prismatic and Rotoide) type. * @ingroup joints * @param dJointGroupID set to 0 to allocate the joint normally. * If it is nonzero the joint is allocated in the given joint group. */ ODE_API dJointID dJointCreatePR (dWorldID, dJointGroupID); /** * @brief Create a new joint of the PU (Prismatic and Universal) type. * @ingroup joints * @param dJointGroupID set to 0 to allocate the joint normally. * If it is nonzero the joint is allocated in the given joint group. */ ODE_API dJointID dJointCreatePU (dWorldID, dJointGroupID); /** * @brief Create a new joint of the Piston type. * @ingroup joints * @param dJointGroupID set to 0 to allocate the joint normally. * If it is nonzero the joint is allocated in the given * joint group. */ ODE_API dJointID dJointCreatePiston (dWorldID, dJointGroupID); /** * @brief Create a new joint of the fixed type. * @ingroup joints * @param dJointGroupID set to 0 to allocate the joint normally. * If it is nonzero the joint is allocated in the given joint group. */ ODE_API dJointID dJointCreateFixed (dWorldID, dJointGroupID); ODE_API dJointID dJointCreateNull (dWorldID, dJointGroupID); /** * @brief Create a new joint of the A-motor type. * @ingroup joints * @param dJointGroupID set to 0 to allocate the joint normally. * If it is nonzero the joint is allocated in the given joint group. */ ODE_API dJointID dJointCreateAMotor (dWorldID, dJointGroupID); /** * @brief Create a new joint of the L-motor type. * @ingroup joints * @param dJointGroupID set to 0 to allocate the joint normally. * If it is nonzero the joint is allocated in the given joint group. */ ODE_API dJointID dJointCreateLMotor (dWorldID, dJointGroupID); /** * @brief Create a new joint of the plane-2d type. * @ingroup joints * @param dJointGroupID set to 0 to allocate the joint normally. * If it is nonzero the joint is allocated in the given joint group. */ ODE_API dJointID dJointCreatePlane2D (dWorldID, dJointGroupID); /** * @brief Destroy a joint. * @ingroup joints * * disconnects it from its attached bodies and removing it from the world. * However, if the joint is a member of a group then this function has no * effect - to destroy that joint the group must be emptied or destroyed. */ ODE_API void dJointDestroy (dJointID); /** * @brief Create a joint group * @ingroup joints * @param max_size deprecated.

NOTES ----- this is an implementation of "lcp_dantzig2_ldlt.m" and "lcp_dantzig_lohi.m". the implementation is split into an LCP problem object (dLCP) and an LCP driver function. most optimization occurs in the dLCP object. a naive implementation of the algorithm requires either a lot of data motion or a lot of permutation-array lookup, because we are constantly re-ordering rows and columns. to avoid this and make a more optimized algorithm, a non-trivial data structure is used to represent the matrix A (this is implemented in the fast version of the dLCP object). during execution of this algorithm, some indexes in A are clamped (set C), some are non-clamped (set N), and some are "don't care" (where x=0). A,x,b,w (and other problem vectors) are permuted such that the clamped indexes are first, the unclamped indexes are next, and the don't-care indexes are last. this permutation is recorded in the array `p'. initially p = 0..n-1, and as the rows and columns of A,x,b,w are swapped, the corresponding elements of p are swapped. because the C and N elements are grouped together in the rows of A, we can do lots of work with a fast dot product function. if A,x,etc were not permuted and we only had a permutation array, then those dot products would be much slower as we would have a permutation array lookup in some inner loops. A is accessed through an array of row pointers, so that element (i,j) of the permuted matrix is A[i][j]. this makes row swapping fast. for column swapping we still have to actually move the data. during execution of this algorithm we maintain an L*D*L' factorization of the clamped submatrix of A (call it `AC') which is the top left nC*nC submatrix of A. there are two ways we could arrange the rows/columns in AC. (1) AC is always permuted such that L*D*L' = AC. this causes a problem when a row/column is removed from C, because then all the rows/columns of A between the deleted index and the end of C need to be rotated downward. this results in a lot of data motion and slows things down. (2) L*D*L' is actually a factorization of a *permutation* of AC (which is itself a permutation of the underlying A). this is what we do - the permutation is recorded in the vector C. call this permutation A[C,C]. when a row/column is removed from C, all we have to do is swap two rows/columns and manipulate C. */ #include #include "config.h" #include "lcp.h" #include #include #include "mat.h" // for testing #include // for testing #include "util.h" //*************************************************************************** // code generation parameters // LCP debugging (mosty for fast dLCP) - this slows things down a lot //#define DEBUG_LCP //#define dLCP_SLOW // use slow dLCP object #define dLCP_FAST // use fast dLCP object // option 1 : matrix row pointers (less data copying) #define ROWPTRS #define ATYPE dReal ** #define AROW(i) (A[i]) // option 2 : no matrix row pointers (slightly faster inner loops) //#define NOROWPTRS //#define ATYPE dReal * //#define AROW(i) (A+(i)*nskip) // use protected, non-stack memory allocation system #ifdef dUSE_MALLOC_FOR_ALLOCA extern unsigned int dMemoryFlag; #define ALLOCA(t,v,s) t* v = (t*) malloc(s) #define UNALLOCA(t) free(t) #else #define ALLOCA(t,v,s) t* v =(t*)dALLOCA16(s) #define UNALLOCA(t) /* nothing */ #endif #define NUB_OPTIMIZATIONS //*************************************************************************** // swap row/column i1 with i2 in the n*n matrix A. the leading dimension of // A is nskip. this only references and swaps the lower triangle. // if `do_fast_row_swaps' is nonzero and row pointers are being used, then // rows will be swapped by exchanging row pointers. otherwise the data will // be copied. static void swapRowsAndCols (ATYPE A, int n, int i1, int i2, int nskip, int do_fast_row_swaps) { int i; dAASSERT (A && n > 0 && i1 >= 0 && i2 >= 0 && i1 < n && i2 < n && nskip >= n && i1 < i2); # ifdef ROWPTRS for (i=i1+1; i 0) { memcpy (tmprow,A+i1*nskip,i1*sizeof(dReal)); memcpy (A+i1*nskip,A+i2*nskip,i1*sizeof(dReal)); memcpy (A+i2*nskip,tmprow,i1*sizeof(dReal)); } for (i=i1+1; i0 && i1 >=0 && i2 >= 0 && i1 < n && i2 < n && nskip >= n && i1 <= i2); if (i1==i2) return; swapRowsAndCols (A,n,i1,i2,nskip,do_fast_row_swaps); #ifdef dUSE_MALLOC_FOR_ALLOCA if (dMemoryFlag == d_MEMORY_OUT_OF_MEMORY) return; #endif tmp = x[i1]; x[i1] = x[i2]; x[i2] = tmp; tmp = b[i1]; b[i1] = b[i2]; b[i2] = tmp; tmp = w[i1]; w[i1] = w[i2]; w[i2] = tmp; tmp = lo[i1]; lo[i1] = lo[i2]; lo[i2] = tmp; tmp = hi[i1]; hi[i1] = hi[i2]; hi[i2] = tmp; tmpi = p[i1]; p[i1] = p[i2]; p[i2] = tmpi; tmpi = state[i1]; state[i1] = state[i2]; state[i2] = tmpi; if (findex) { tmpi = findex[i1]; findex[i1] = findex[i2]; findex[i2] = tmpi; } } // for debugging - check that L,d is the factorization of A[C,C]. // A[C,C] has size nC*nC and leading dimension nskip. // L has size nC*nC and leading dimension nskip. // d has size nC. #ifdef DEBUG_LCP static void checkFactorization (ATYPE A, dReal *_L, dReal *_d, int nC, int *C, int nskip) { int i,j; if (nC==0) return; // get A1=A, copy the lower triangle to the upper triangle, get A2=A[C,C] dMatrix A1 (nC,nC); for (i=0; i 1e-8) dDebug (0,"L*D*L' check, maximum difference = %.6e\n",diff); } #endif // for debugging #ifdef DEBUG_LCP static void checkPermutations (int i, int n, int nC, int nN, int *p, int *C) { int j,k; dIASSERT (nC>=0 && nN>=0 && (nC+nN)==i && i < n); for (k=0; k= 0 && p[k] < i); for (k=i; k C,N; // index sets int last_i_for_solve1; // last i value given to solve1 dLCP (int _n, int _nub, dReal *_Adata, dReal *_x, dReal *_b, dReal *_w, dReal *_lo, dReal *_hi, dReal *_L, dReal *_d, dReal *_Dell, dReal *_ell, dReal *_tmp, int *_state, int *_findex, int *_p, int *_C, dReal **Arows); // the constructor is given an initial problem description (A,x,b,w) and // space for other working data (which the caller may allocate on the stack). // some of this data is specific to the fast dLCP implementation. // the matrices A and L have size n*n, vectors have size n*1. // A represents a symmetric matrix but only the lower triangle is valid. // `nub' is the number of unbounded indexes at the start. all the indexes // 0..nub-1 will be put into C. ~dLCP(); int getNub() { return nub; } // return the value of `nub'. the constructor may want to change it, // so the caller should find out its new value. // transfer functions: transfer index i to the given set (C or N). indexes // less than `nub' can never be given.

* Point Direction; * }; * * But it actually maps three different things: * - a segment, when 0 <= t <= d * - a half-line, when 0 <= t < +infinity, or -infinity < t <= d * - a line, when -infinity < t < +infinity * * In Opcode, we support segment queries, which yield half-line queries by setting d = +infinity. * We don't support line-queries. If you need them, shift the origin along the ray by an appropriate margin. * * In short, the lower bound is always 0, and you can setup the higher bound "d" with RayCollider::SetMaxDist(). * * Query |segment |half-line |line * --------|-------------------|---------------|---------------- * Usages |-shadow feelers |-raytracing |- * |-sweep tests |-in/out tests | * * FIRST CONTACT: * * - You can setup "first contact" mode or "all contacts" mode with RayCollider::SetFirstContact(). * - In "first contact" mode we return as soon as the ray hits one face. If can be useful e.g. for shadow feelers, where * you want to know whether the path to the light is free or not (a boolean answer is enough). * - In "all contacts" mode we return all faces hit by the ray. * * TEMPORAL COHERENCE: * * - You can enable or disable temporal coherence with RayCollider::SetTemporalCoherence(). * - It currently only works in "first contact" mode. * - If temporal coherence is enabled, the previously hit triangle is cached during the first query. Then, next queries * start by colliding the ray against the cached triangle. If they still collide, we return immediately. * * CLOSEST HIT: * * - You can enable or disable "closest hit" with RayCollider::SetClosestHit(). * - It currently only works in "all contacts" mode. * - If closest hit is enabled, faces are sorted by distance on-the-fly and the closest one only is reported. * * BACKFACE CULLING: * * - You can enable or disable backface culling with RayCollider::SetCulling(). * - If culling is enabled, ray will not hit back faces (only front faces). * * * * \class RayCollider * \author Pierre Terdiman * \version 1.3 * \date June, 2, 2001 */ /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// /** * This class describes a face hit by a ray or segment. * This is a particular class dedicated to stabbing queries. * * \class CollisionFace * \author Pierre Terdiman * \version 1.3 * \date March, 20, 2001 */ /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// /** * This class is a dedicated collection of CollisionFace. * * \class CollisionFaces * \author Pierre Terdiman * \version 1.3 * \date March, 20, 2001 */ /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// // Precompiled Header #include "Stdafx.h" using namespace Opcode;

Meshes can be defined in a lot of ways, and here we * try to support most of them. * * Basically you have two options: * - callbacks, if OPC_USE_CALLBACKS is defined in OPC_Settings.h. * - else pointers. * * If using pointers, you can also use strides or not. Strides are used when OPC_USE_STRIDE is defined. * * * CALLBACKS: * * Using callbacks is the most generic way to feed OPCODE with your meshes. Indeed, you just have to give * access to three vertices at the end of the day. It's up to you to fetch them from your database, using * whatever method you want. Hence your meshes can lie in system memory or AGP, be indexed or not, use 16 * or 32-bits indices, you can decompress them on-the-fly if needed, etc. On the other hand, a callback is * called each time OPCODE needs access to a particular triangle, so there might be a slight overhead. * * To make things clear: geometry & topology are NOT stored in the collision system, * in order to save some ram. So, when the system needs them to perform accurate intersection * tests, you're requested to provide the triangle-vertices corresponding to a given face index. * * Ex: * * \code * static void ColCallback(udword triangle_index, VertexPointers& triangle, udword user_data) * { * // Get back Mesh0 or Mesh1 (you also can use 2 different callbacks) * Mesh* MyMesh = (Mesh*)user_data; * // Get correct triangle in the app-controlled database * const Triangle* Tri = MyMesh->GetTriangle(triangle_index); * // Setup pointers to vertices for the collision system * triangle.Vertex[0] = MyMesh->GetVertex(Tri->mVRef[0]); * triangle.Vertex[1] = MyMesh->GetVertex(Tri->mVRef[1]); * triangle.Vertex[2] = MyMesh->GetVertex(Tri->mVRef[2]); * } * * // Setup callbacks * MeshInterface0->SetCallback(ColCallback, udword(Mesh0)); * MeshInterface1->SetCallback(ColCallback, udword(Mesh1)); * \endcode * * Of course, you should make this callback as fast as possible. And you're also not supposed * to modify the geometry *after* the collision trees have been built. The alternative was to * store the geometry & topology in the collision system as well (as in RAPID) but we have found * this approach to waste a lot of ram in many cases. * * * POINTERS: * * If you're internally using the following canonical structures: * - a vertex made of three 32-bits floating point values * - a triangle made of three 32-bits integer vertex references * ...then you may want to use pointers instead of callbacks. This is the same, except OPCODE will directly * use provided pointers to access the topology and geometry, without using a callback. It might be faster, * but probably not as safe. Pointers have been introduced in OPCODE 1.2. * * Ex: * * \code * // Setup pointers * MeshInterface0->SetPointers(Mesh0->GetFaces(), Mesh0->GetVerts()); * MeshInterface1->SetPointers(Mesh1->GetFaces(), Mesh1->GetVerts()); * \endcode * * * STRIDES: * * If your vertices are D3D-like entities interleaving a position, a normal and/or texture coordinates * (i.e. if your vertices are FVFs), you might want to use a vertex stride to skip extra data OPCODE * doesn't need. Using a stride shouldn't be notably slower than not using it, but it might increase * cache misses. Please also note that you *shouldn't* read from AGP or video-memory buffers ! * * * In any case, compilation flags are here to select callbacks/pointers/strides at compile time, so * choose what's best for your application.

I think the cause is when you set surface.mu = dInfinity; // the friction force is too high so it just hang the capsule there. // So the good cure for this is to set mu = around 1.5 (in my case) // For StepFast1, this become as solid as rock : StepFast1 just approximate // friction force. // NOTES from Croteam's Alen //As a side note... there are some extra contacts that can be generated //on the edge between two triangles, and if the capsule penetrates deeply into //the triangle (usually happens with large mass or low FPS), some such //contacts can in some cases push the capsule away from the edge instead of //away from the two triangles. This shows up as capsule slowing down a bit //when hitting an edge while sliding along a flat tesselated grid of //triangles. This is only if capsule is standing upwards. //Same thing can appear whenever a smooth object (e.g sphere) hits such an //edge, and it needs to be solved as a special case probably.

If there are incoming or outgoing windows, user input is disabled until the transition animation is complete. Each window is a menu tree (a menuframework_s struct with submenus.) The purpose of the animation code is to determine what x-axis offset each window should be drawn at (that is, what number of pixels should be added to the x-axis of the window when it is drawn.) The x offset for each window is recalculated each frame so that the windows tile neatly alongside each other, slide across the screen, etc. The main menu is a special case, in that it will shrink into a sidebar instead of appearing partially off screen. Architecturally, this is done with a simple finite-state machine. */ // M_Interp - responsible for animating the transitions as menus are added and // removed from the screen.

I'm afraid this is complicated enough to justify a small essay. The reason this is so complicated is because of those constraints. Menu width, menu item x, and menu item y are all "linkable" attributes, meaning they can be linked together so they always have the same value. If updated in one place, the updates show up everywhere else. Here's the problem: these linkable attributes depend on each other, sometimes in complex ways. For example, take a table with two rows: ITEMA ITEMB ITEMC ITEMD ITEME ITEMF ITEMA and ITEMD's x-coordinates are linked, ITEMB and ITEME's x-coordinates are linked, etc. Now the easy way to do this would be to lay out the entirety of row 1, then the entirety of row 2. But suppose you have a case where ITEMA and ITEME are narrow, while ITEMD and ITEMB are wide? Here's what the table looks like before it's been laid out at all: [ITEMA][=ITEMB=][ITEMC] [=ITEMD=][ITEME][ITEMF] Laying out the first row goes well. The required amount of space is inserted between ITEMA and ITEMB, and because ITEMB and ITEME are linked, that change is propagated to the second row automatically. Likewise for the space between ITEMB and ITEMC, and the propagation from ITEMC to ITEMF. [ITEMA]---[=ITEMB=]---[ITEMC] [=ITEMD=]-[ITEME]-----[ITEMF] Then the second row is laid out. Since ITEMD is wider, the space between it and ITEME isn't enough, so ITEME has to be moved for the space to be sufficient. Because ITEMF is still far enough away from ITEME, it doesn't get moved, and as a result, ITEMC doesn't get moved either! ITEMC's position is no longer valid, so the first row has to be laid out again. [ITEMA]-----[=ITEMB=]-[ITEMC] [=ITEMD=]---[ITEME]---[ITEMF] To insure a proper layout, Menu_Arrange is simply called over and over again until no more movement is detected. Actually, the number of calls is limited at 5 to prevent things from getting too out of hand. ============= */ static int changes = 0; #define MENU_INCREASELINK(l,v) \ {\ if ((l).status == linkstatus_link) \ {\ if (*((l).ptr) < v) \ { \ changes++;

Alien Arena does not use it. 2. simplifies filesystem modifications link command removed because: 1. it is probably obsolete (hack for DOS to simulate Unix link?) 2. simplifies filesystem modifications 3. might be a security issue? basedir cvar removed because: 1. it is probably an unnecessary complication. --- Original Quake File System Comments --- All of Quake's data access is through a hierchal file system, but the contents of the file system can be transparently merged from several sources. The "base directory" is the path to the directory holding the quake.exe and all game directories. The sys_* files pass this to host_init in quakeparms_t->basedir. This can be overridden with the "-basedir" command line parm to allow code debugging in a different directory. The base directory is only used during filesystem initialization. The "game directory" is the first tree on the search path and directory that all generated files (savegames, screenshots, demos, config files) will be saved to. This can be overridden with the "-game" command line parameter. The game directory can never be changed while quake is executing. This is a precacution against having a malicious server instruct clients to write files over areas they shouldn't. ------------------------------------------------------------------------------- */ #ifdef HAVE_CONFIG_H #include "config.h" #endif #if defined HAVE_UNISTD_H #include #elif defined HAVE_DIRECT_H /* for _getcwd in Windows */ #include #endif #if defined HAVE_SYS_STAT_H #include #endif #if defined HAVE_ZLIB # include #endif #include #include "qcommon.h" #include "game/q_shared.h" #include "unix/glob.h" #if !defined HAVE__GETCWD && defined HAVE_GETCWD #define _getcwd getcwd #endif char fs_gamedir[MAX_OSPATH]; cvar_t *fs_gamedirvar; // for the "game" cvar, default is "arena" /* --- Search Paths --- * * Pathname strings do not include a trailing '/' * The last slot is guard, containing an empty string * The bot pathname strings do not include the "botinfo" part. * */ #define GAME_SEARCH_SLOTS 7 char fs_gamesearch[GAME_SEARCH_SLOTS][MAX_OSPATH]; #define BOT_SEARCH_SLOTS 3 char fs_botsearch[BOT_SEARCH_SLOTS][MAX_OSPATH]; /** * @brief Initialize paths: data1, arena, botinfo, etc. * * @note This gets executed after command line "+set" commands are executed * the first time.

A smallish enough vertex array buffer is used to enable a balance of fast transfers of smaller chunks of data to the 3D card (with - hopefully - a decent level of amortization) and a reduced number of API calls. This system allows up to MAX_VERTS verts to be transferred at once.

Notes on shadow rendering: CRX uses a combination of shadowmapping and stencil volumes for it's shadowing effects. The shadow maps are used for dynamic shadows only, while the stencil volumes are used for static items and vegetation. There are a couple of compelling reaons why we do this. First, the goal is speed. It is slightly faster to create the volumes than it is to render the mesh to create a shadow caster. Another consideration is that the stencil volumes cast on any object without the need for a shader to be present. We are able to create a soft shadow effect by blitting the stencil buffer to an offscreen FBO, blurring it in a GLSL shader, then rendering the image on a single quad overlay with the correct blending. The drawbacks are that we do not have fading penumbras(this could change depending on what the idtech 4 shadow code looks like). Dynamic shadows are handled via shadowmaps since dynamic lighting is handled using GLSL. This allows us to easily create fading penumbras with dynamic lights. While it is slightly slower, it allows for an excellent, and accurate effect. */ #ifdef HAVE_CONFIG_H #include "config.h" #endif #include "r_local.h" #include "r_ragdoll.h" /* =============== SHADOW VOLUMES =============== */ glStencilFuncSeparatePROC qglStencilFuncSeparate = NULL;

Credits 8. Copyright Information 1. INTRODUCTION ALIEN ARENA is a standalone 3D first person online deathmatch shooter crafted from the original source code of Quake II and Quake III, released by id Software under the GPL license. With features including 32 bit graphics, new particle engine and effects, light blooms, reflective water, hi resolution textures and skins, hi poly models, stain maps, ALIEN ARENA pushes the envelope of graphical beauty rivaling today's top games. The game features 37 levels, which can be played online against other players, or against the built in CodeRED bots. Alien Arena offers CTF, AOA (All Out Assault) mode, in which players can climb into vehicles to do battle, Deathball, Team Core Assault, where teams disable enemy power nodes to eventually destroy the enemy power core, and Cattle Prod, where teams guide cows into goal areas. Simply go into the multiplayer menu to start a server, change the game rules , and choose a map to play on. You can also select from five different mutators(instagib, rocket arena, excessive, low grav, regen, and vampire) to further customize your game experience. Alien Arena : Many are called, only one will reign supreme. Eternal war ravaged the vastness of infinite space. For as far back into the ages as the memories of the galaxies oldest races could reach, it had been this way. Planet at war with planet, conflicts ending with a burned cinder orbiting a dead sun and countless billions sent screaming into oblivion. War, endless and eternal, embracing all the peoples of the cosmos. Scientific triumphs heralded the creation of ever more deadly weapons until the very fabric of the universe itself was threatened. Then came the call. Some said it was sent by an elder race, legendary beings of terrifying power who had existed since the birth of the stars and who now made their home beyond the fringes of known creation, others whispered fearfully and looked to the skies for the coming of their gods. Perhaps it didn't matter who had sent the call, for all the people of the stars could at least agree that the call was there. The wars were to end - or they would be ended. In a demonstration of power whoever had sent the call snuffed out the homeworld of the XXXX, the greatest empire of all the stars, in a heartbeat. One moment it was there, the next it was dust carried on the solar winds. All races had no choice but to heed the call. For most the call was a distant tug, a whispered warning that the wars were over, but for the greatest hero of each people it was more, it was a fire raging through their blood, a call to a new war, to the battle to end all battles. That fire burns in your blood, compelling you, the greatest warrior of your people, to fight in a distant and unknown arena, your honor and the future of your race at stake. Across the stars you traveled in search of this arena where the mightiest of the mighty would do battle, where you would stand face to face with your enemies in a duel to the death. Strange new weapons awaited you, weapons which you would have to master if you were to survive and emerge victorious from the complex and deadly arenas in which you were summoned to fight. The call to battle beats through your heart and soul like the drums of war. Will you be the one to rise through the ranks and conquer all others, the one who stands proud as the undefeated champion of the Alien Arena? 2. SYSTEM REQUIREMENTS 1.8 GHz CPU 1.5 GiB RAM 1.2 GiB hard disk space 3D Accelerator with at least 128 MiB texture memory available 3. GETTING STARTED * INSTALLATION (Windows) Installation has been made very simple. After downloading, simply click on the .exe file and the installation will begin. Follow the instructions of the Innosetup program. If you are running Windows, you should have administrative privileges. If not, you may get some errors when the program tries to write the uninstall information to the registry. If so, simply click "ignore", and the installation will continue without problem. Once finished, you can click on the Alien Arena icon that has been placed on your desktop to start a game or the Alien Arena Chat icon to join the IRC chat channel. (Linux) See the README and INSTALL documentation files. * BASIC COMMANDS ALIEN ARENA works very much like Quake and Unreal Tournament, with a few notable exceptions. The player will have the following weapons: 1. Blaster (automatically equipped at spawn) 2. Alien Disruptor 3. Chaingun 4. Flame Thrower 5. Rocket Launcher 6. Alien Smart Gun 7. Disruptor 8. Alien Vaporizer 9. Violator (automatically equipped at spawn) Weapons also have alternate firing modes. In you controls menu, select your secondary fire key and this will allow you to use these modes. The default key for alternate fire is MOUSE2 (right click). There are new powerups such as haste and sproing, in addition to the venerable quad damage and invulnerability. It would be advisable for you to change video settings for however you wish to view the game, and what gives you reasonable performance. The game's default settings are at a mid range setting, so try tweaking them or adding/removing effects depending on your framerate. If you wish to see your framerate, you can type "set cl_drawfps 1" at the console (brought down using the ` key). ALIEN ARENA also allows for colored names just as Quake 3, using the ^ character followed by a number to set the color. Movement is based on Quake 2 physics, allowing strafejumping, doublejumping, and other Quake type movements. In Alien Arena, you can also dodge, similarly to Unreal Tournament, by pressing a strafe key, releasing it fully, and pressing it again. Dodges can be linked together into sequences, similar to strafejumping, called strafedodging. * COMPLETING LEVELS In Alien Arena you can play a single player tournament where your goal will to be to reach the fraglimit before a bot does. If you fail, you will be forced to repeat the level until you do. These rules can be changed in the menu system. You can also play people online, where your goal is to reach the fraglimit before your opponents, or by scoring the most frags before the time limit is up. In CTF mode, you'll be on a team, and trying to capture the enemy's flag and return it to your own flag's location. The team reaching the capture limit first, wins. In Deathball, the goal is to score as many points as possible, either by killing your opponents, or by finding the ball and shooting it into the goal (worth 10 frags). When a player is inside of the deathball, he is defensless. In Team Core Assault, your goal is to disable your enemy teams power nodes, then destroy the central spider node. You can only do damage to the spider node when all other power nodes are disabled. In Cattle Prod, each team tries to guide the cows in the middle of the map to the goals in the enemy base. Cows follow players after a connection is automatically established between the cow and the player, when the player is within sight and range of the cow. This connection is broken when either the player or the cow is killed. * CONNECTING TO A SERVER You can either select "join server" from the "multiplayer" menu and select a server in the list, or you can use the CodeRED Galaxy server browser (windows only). In the in-game browser, servers are listed in order of ping, with lowest ping at the top of the list. 4. THE CODERED ACE BOT Bots are a built in feature of ALIEN ARENA 2009. Several bots are already configured for multiplayer games, and in Alien Arena, each level has a specific bot file for what bots are to be played in each level. To add a bot, type "sv addbot name model/skin", and to remove a bot type "sv removebot name". You can also add bots in the menu, in the deathmatch/bots flags area. In your Deathmatch options, you can configure other options such as chatting, node saving, and aiming. These bots are fully configurable using the Botconfigurator program. You can change their skill levels, accuracy, weapon favoring, awareness, and chat strings. Skill level 0 bots are quite easy to beat. Skill level 1 bots are a little tougher, and do more dodging and are more accurate. Skill level 2 bots do more advanced dodging, rocket jumping, and are even more accurate. Level 3 bots are extremely skilled, and will strafe, and strafe jump around the level. They will also taunt you after killing you. If in Alien Arena, you play the single player tournament against the bots, selecting "easy" will make all bots skill level 0. Selecting "normal" will leave them at whatever level they are configured. Selecting "hard" will make them all move up 1 skill level. 5. THE REWARDS SYSTEM In Alien Arena, you are given points for getting kills (one point for kill), two points for special kills (midair kills, gib kills), and five extra points for killing sprees. These points add up, and when these points reach the point threshold (set by the server), they can be used to purchase temporary powerups: invisibility, haste, and sproing. Invisibility makes you appear like glass, haste makes your jumps increase your speed dramatically (linking jumps together makes this difference even more drastic), and sproing greatly increases the player jump height. These powerups last for 30 seconds. 6. HOW TO UNINSTALL ALIEN ARENA To uninstall Alien Arena, simply go to your start programs menu, select your Alien Arena folder, and click on "Uninstall". You can also go into your control panel, and uninstall Alien Arena in the programs and software section. For Linux users, see the README documentation file. 7.

An example crontab that would check each server is running every ten minutes would look like this: */10 * * * * /home/aa/cron/kill-runaway-crx-ded */10 * * * * /home/aa/cron/launch-server ctf.cfg >/dev/null 2>&1 */10 * * * * /home/aa/cron/launch-server teamdm.cfg >/dev/null 2>&1 Additonally, a master server would have the following line in the crontab (most people won't want this): */10 * * * * /home/aa/cron/check-master >/dev/null 2>&1 Don't forget to edit the launch-server/check-master scripts to set the paths correctly for your executable. 'svstat' is a ruby script that will query local servers and produce some nice output for server admin. 'rcon' is a ruby script that sends rcon commands to servers 'view-ip-log' is a shell script that parses the contents of the IP log. alien-arena-7.66+dfsg/Tools/LinuxScripts/randomgravity0000700000175000017500000000153512161402015022174 0ustar zero79zero79#!/bin/sh # Random gravity script for Alien Arena # Written by Tony Jackson 15/07/2008 # # Configure below and run using: # ./randomgravity & # To stop use 'fg' and ctrl-c # Calls Alien Arena rcon script - you must have ruby installed ######################## # CONFIGURATION # ######################## aapath=~/alienarena2008 serverip=localhost serverport=27910 serverpass=your_rcon_pass_here delay=5 maxgravity=1400 mingravity=100 ######################## # END OF CONFIGURATION # ######################## # Do not edit below this line! while [ 1 ] do sleep $delay random=`dd if=/dev/urandom count=1 2> /dev/null | cksum | cut -f1 -d" "` random=$((($random%($maxgravity-$mingravity))+$mingravity)) # echo "Set gravity to $random" $aapath/Tools/LinuxScripts/rcon $serverip:$serverport $serverpass set sv_gravity $random >/dev/null 2>&1 done alien-arena-7.66+dfsg/Tools/LinuxScripts/kill-runaway-crx-ded0000700000175000017500000000026512161402015023250 0ustar zero79zero79#!/bin/sh for TPPID in `ps -eo pid,pcpu,comm | grep crx-ded | grep -v grep | awk '{print $1":"$2}' | awk 'BEGIN {FS=":"}{ if ($2 > 20.0){print $1} }'` do /bin/kill -9 $TPPID done alien-arena-7.66+dfsg/Tools/LinuxScripts/check-configs0000700000175000017500000000503112161402015022004 0ustar zero79zero79#!/usr/bin/env ruby =begin ALIEN ARENA CONFIG CHECK (for server admins) V1.0 Copyright (C) 2009 Tony Jackson 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.

Basic Installation ================== Briefly, the shell commands `./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. 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 bug. Until the bug is fixed you can use this workaround: CONFIG_SHELL=/bin/bash /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.
