`------------------------------------------ http://icculus.org/quake3 ---------'

The intent of this project is to provide a baseline Quake 3 which may be used
for further development. Some of the major features currently implemented are:

  * SDL backend for unix-like operating systems
  * OpenAL sound API support (multiple speaker support and better sound
    quality)
  * Full x86_64 support on Linux
  * MinGW compilation support on Windows and cross compilation support on Linux
  * AVI video capture of demos
  * Much improved console autocompletion
  * Persistent console history
  * Colorized terminal output
  * Optional Ogg Vorbis support
  * Much improved QVM tools
  * Support for various esoteric operating systems (see
    http://icculus.org/quake3/?page=status)
  * Many, many bug fixes

The map editor and associated compiling tools are not included. We suggest you
use a modern copy from http://www.qeradiant.com/.

The original id software readme that accompanied the Q3 source release has been
renamed to id-readme.txt so as to prevent confusion. Please refer to the
web-site for updated status.


--------------------------------------------- Compilation and installation -----

For *nix
  1. Change to the directory containing this readme.
  2. Run 'make'.

For Windows, using MinGW
  1. Download and install MinGW and MSys from http://www.mingw.org/.
  2. Download http://www.libsdl.org/extras/win32/common/directx-devel.tar.gz
     and untar in into your MinGW directory (usually C:\MinGW).
  3. Open an MSys terminal, and follow the instructions for compiling on *nix.

For Windows, using MSVC
  1. Run Visual Studio and open the quake3.sln file in the code/win32/msvc
     directory.
  2. Build.
  3. Copy the resultant Quake3.exe to your quake 3 directory, make a backup if
     you want to keep your original. If you wish to use native libraries, copy
     the resultant dlls to your baseq3 directory.

Installation, for *nix
  1. Set the COPYDIR variable in the shell to be where you installed Quake 3
     to.  By default it will be /usr/local/games/quake3 if you haven't set it.
     This is the path as used by the original Linux Q3 installer and subsequent
     point releases.
  2. Run 'make copyfiles'.

It is also possible to cross compile for Windows under *nix using MinGW. A
script is available to build a cross compilation environment from
http://www.libsdl.org/extras/win32/cross/build-cross.sh. The gcc/binutils
version numbers that the script downloads may need to be altered. After you
have successfully run this script cross compiling is simply a case of using
'./cross-make-mingw.sh' in place of 'make'.

If the make based build system is being used (i.e. *nix or MinGW), the
following variables may be set, either on the command line or in
Makefile.local:

  OPTIMIZE          - use this for custom CFLAGS
  DEFAULT_BASEDIR   - extra path to search for baseq3 and such
  BUILD_SERVER      - build the 'ioq3ded' server binary
  BUILD_CLIENT      - build the 'ioquake3' client binary
  BUILD_CLIENT_SMP  - build the 'ioquake3-smp' client binary
  BUILD_GAME_SO     - build the game shared libraries
  BUILD_GAME_QVM    - build the game qvms
  USE_SDL           - use the SDL backend where available
  USE_OPENAL        - use OpenAL where available
  USE_OPENAL_DLOPEN - link with OpenAL at runtime
  USE_CODEC_VORBIS  - enable Ogg Vorbis support
  USE_LOCAL_HEADERS - use headers local to ioq3 instead of system ones
  USE_CCACHE        - use ccache compiler caching tool
  COPYDIR           - the target installation directory

The defaults for these variables differ depending on the target platform.

  s_alPrecache            - cache OpenAL sounds before use
  s_alGain                - the value of AL_GAIN for each source
  s_alSources             - the total number of sources (memory) to allocate
  s_alDopplerFactor       - the value passed to alDopplerFactor
  s_alDopplerSpeed        - the value passed to alDopplerVelocity
  s_alMinDistance         - the value of AL_REFERENCE_DISTANCE for each source
  s_alRolloff             - the value of AL_ROLLOFF_FACTOR for each source

------------------------------------------------------------ Miscellaneous -----

Using shared libraries instead of qvm
  To force Q3 to use shared libraries instead of qvms run it with the following
  parameters: +set sv_pure 0 +set vm_cgame 0 +set vm_game 0 +set vm_ui 0

Using Demo Data Files
  Copy demoq3/pak0.pk3 from the demo installer to your baseq3 directory. The
  qvm files in this pak0.pk3 will not work, so you have to use the native
  shared libraries or qvms from this project. To use the new qvms, they must be
  put into a pk3 file. A pk3 file is just a zip file, so any compression tool
  that can create such files will work. The shared libraries should already be
  in the correct place. Use the instructions above to use them.

  Please bear in mind that you will not be able to play online using the demo
  data, nor is it something that we like to spend much time maintaining or
  supporting.

64bit mods
  If you wish to compile external mods as shared libraries on a 64bit platform,
  and the mod source is derived from the id Q3 SDK, you will need to modify the
  interface code a little. Open the files ending in _syscalls.c and change
  every instance of int to long in the declaration of the syscall function
  pointer and the dllEntry function. Also find the vmMain function for each
  module (usually in cg_main.c g_main.c etc.) and similarly replace every
  instance of int in the prototype with long.

  Note if you simply wish to run mods on a 64bit platform you do not need to
  recompile anything since by default Q3 uses a virtual machine system.

Creating mods compatible with Q3 1.32b
  If you're using this package to create mods for the last official release of
  Q3, it is necessary to pass the commandline option '-vq3' to your invocation
  of q3asm. This is because by default q3asm outputs an updated qvm format that
  is necessary to fix a bug involving the optimizing pass of the x86 vm JIT
  compiler. See http://www.quakesrc.org/forums/viewtopic.php?t=5665 (if it
  still exists when you read this) for more details.


------------------------------------------------------------- Contributing -----

Please send all patches to bugzilla (https://bugzilla.icculus.org), or join the
mailing list (quake3-subscribe@icculus.org) and submit your patch there.  The
best case scenario is that you submit your patch to bugzilla, and then post the
URL to the mailing list. If you're too lazy for either method, then it would be
better if you emailed your patches to zakk@icculus.org directly than not at
all.

The focus for ioq3 to develop a stable base suitable for further development,
and provide players with the same Quake 3 experience they've had for years.
As such ioq3 does not have any significant graphical enhancements and none are
planned at this time. However, improved graphics and sound patches will be
accepted as long as they are entirely optional, do not require new media and
are off by default.
