Name of this project: icculus.org/quake3
URL: http://www.icculus.org/quake3
Hello and welcome to the Quake 3 source repository on icculus.org
I'll be your maintainer, zakk@icculus.org, please send all your patches to 
the bugzilla: https://bugzilla.icculus.org, or join the mailing list 
(quake3-subscribe@icculus.org) and submit your patch there.
Best case scenario is you subscribe to the ml, submit your patch to
bugzilla, and then post the url to the mailing list.

If you're too lazy for either method, then I would rather
you e-mailed your patches to me directly than not at all.

The intent of this is to give people a baseline Quake 3.
Bug fixes, SDL port, OpenAL, security, etc.
Extra graphics and sound will be accepted as long as they are entirely
optional and off by default.

The map editor isn't included, get a modern copy from here:
http://www.qeradiant.com/

The id software readme has been renamed to id-readme.txt
so as to prevent confusion.

Refer to the web-site for updated status, enjoy!

Compiling
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cd code/unix && make

Installing under Linux
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In code/unix edit the Makefile's COPYDIR variable to be where you installed
quake 3 to. By default it will be set to /usr/local/games/quake3 if you
haven't set it.

Then run "make copyfiles", beware that this will overwrite any binaries
installed previously, even id ones.

Using shared libraries instead of qvm
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To make quake3 prefer shared libraries instead of qvm 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
~~~~~~~~~~~~~~~~~~~~~
you only need demoq3/pak0.pk3 from the demo installer. The qvm files inside
pak0.pk3 will not work, you have to use the native shared libraries from this
project. To do so copy or link ui*.so, qagame*.so, cgame*.so from baseq3 to
demoq3 and run quake3 with the parameters described above.

64bit mods
~~~~~~~~~~
To compile working(!) shared libraries for 64bit mods the vmMain and
dllEntry functions as well as the syscall pointer have to be changed
to accept and return long instead of int.

Compiling under windows using MinGW
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

It is possible to compile ioQ3 using the MinGW (Minimalist GNU for Windows)
toolset. It's a little more involved than compiling for linux; steps are as
follows:

1. Download and install MinGW and MSys from http://www.mingw.org/.
2. Download and install the DirectX 9 SDK from
   http://msdn.microsoft.com/directx/. Previous versions of the SDK will
   probably work, but they have not been tested.
3. Find the following in DXSDK/Include/dinput.h...

      } DIDEVICEINSTANCEW, *LPDIDEVICEINSTANCEW;
      #ifdef UNICODE
      typedef DIDEVICEINSTANCEW DIDEVICEINSTANCE;
      typedef LPDIDEVICEINSTANCEW LPDIDEVICEINSTANCE;
      #else
      typedef DIDEVICEINSTANCEA DIDEVICEINSTANCE;
      typedef LPDIDEVICEINSTANCEA LPDIDEVICEINSTANCE;
      #endif // UNICODE

      typedef const DIDEVICEINSTANCEA *LPCDIDEVICEINSTANCEA;
      typedef const DIDEVICEINSTANCEW *LPCDIDEVICEINSTANCEW;
   >  #ifdef UNICODE
   >  typedef DIDEVICEINSTANCEW DIDEVICEINSTANCE;
   >  typedef LPCDIDEVICEINSTANCEW LPCDIDEVICEINSTANCE;
   >  #else
   >  typedef DIDEVICEINSTANCEA DIDEVICEINSTANCE;
   >  typedef LPCDIDEVICEINSTANCEA LPCDIDEVICEINSTANCE;
   >  #endif // UNICODE
      typedef const DIDEVICEINSTANCE  *LPCDIDEVICEINSTANCE;

   ...and comment out/remove the duplicated code marked by '>'.

4. If you didn't install the DirectX SDK in C:\DXSDK\, edit DXSDK_DIR in
   code/unix/Makefile to reflect the new location.
5. Perform the usual precompilation sacrificial ritual.
6. Open an MSys terminal, and follow the instructions for compiling on Linux.
