JPEG library

code/jpeg-6 code/libs/jpeg6 Copyright (C) 1991-1995, Thomas G. Lane

Permission is hereby granted to use, copy, modify, and distribute this software (or portions thereof) for any purpose, without fee, subject to these conditions: (1) If any part of the source code for this software is distributed, then this README file must be included, with this copyright and no-warranty notice unaltered; and any additions, deletions, or changes to the original files must be clearly indicated in accompanying documentation. (2) If only executable code is distributed, then the accompanying documentation must state that "this software is based in part on the work of the Independent JPEG Group". (3) Permission for use of this software is granted only if the user accepts full responsibility for any undesirable consequences; the authors accept NO LIABILITY for damages of any kind.

These conditions apply to any software derived from or based on the IJG code, not just to the unmodified library. If you use our work, you ought to acknowledge us.

NOTE: unfortunately the README that came with our copy of the library has been lost, so the one from release 6b is included instead. There are a few 'glue type' modifications to the library to make it easier to use from the engine, but otherwise the dependency can be easily cleaned up to a better release of the library.

GENERAL NOTES

A short summary of the file layout:

code/ Quake III Arena source code ( renderer, game code, OS layer etc. ) code/bspc bot routes compiler source code lcc/ the retargetable C compiler ( produces assembly to be turned into qvm bytecode by q3asm ) code/tools/q3asm/ assembly to qvm bytecode compiler

While we made sure we were still able to compile the game on Windows, GNU/Linux and Mac, this build didn't get any kind of extensive testing so it may not work completely right. Whenever an id game is released under GPL, several projects start making the source code more friendly to nowaday's compilers and environements. If you are picking up this release weeks/months/years after we uploaded it, you probably want to look around on the net for cleaned up versions of this codebase as well.

COMPILING ON WIN32

VC9 / Visual C++ 2008 project files are provided: code/quake3.sln

To compile the qvms, you need to run some batch files: you will need to have lcc.exe q3cpp.exe q3rcc.exe and q3asm.exe in your path ( some precompiled binaries are provided in lcc/bin and code/win32/mod-sdk-setup/bin ) the qvm batch files are in code/game code/cgame code/q3_ui code/ui ..

COMPILING ON GNU/LINUX and OpenSolaris/Solaris

A Makefile is available in the base source folder. Just run "make" to start compiling. As Scons is still used for the compilation, you will need the perl interpreter on your station.

All needed tools will be compiled and you will found binaries and QVMs in the "install" subfolder.

You can also start "make mod-pk3" to have a pk3 with only the QVMs engine in the "install" subfolder.

If you only need a statically linked dedicated server, you can also start "make engine-static"

Packagers, you can "export DEFAULT_BASEDIR" from the shell to setup a default basepath where you want the game installed by your package. Then the engine will search the game there before anywhere else.

COMPILING ON MAC

We are awaiting a source drop of updated an XCode project file
