They take advantage of gcc's vector_size attribute and so only cross, dot, qmul, qvmul and qrot (create rotation quaternion from two vectors) are needed at this stage as basic (per-component) math is supported natively by gcc. The provided functions work on horizontal (array-of-structs) data, ie a vec4d_t or vec4f_t represents a single vector, or traditional vector layout. Vertical layout (struct-of-arrays) does not need any special functions as the regular math can be used to operate on four vectors at a time. Functions are provided for loading a vec4 from a vec3 (4th element set to 0) and storing a vec4 into a vec3 (discarding the 4th element). With this, QF will require AVX2 support (needed for vec4d_t). Without support for doubles, SSE is possible, but may not be worthwhile for horizontal data. Fused-multiply-add is NOT used because it alters the results between unoptimized and optimized code, resulting in -mfma really meaning -mfast-math-anyway. I really do not want to have to debug issues that occur only in optimized code. |

==========================================================================
WARNING: This is not intended for inexperienced users, binaries are available on request.
QuakeForge may take several hours from bootstrap to the completion
of make install on some systems
To build win32(mingw) QuakeForge bins you will need to download and install cygwin, and the Microsoft DirectX SDK. Cygwin can be found at http://www.cygwin.org
Once cygwin is installed along with the appropriate developement modules, copy dinput.h from the DirectX SDK and place it in /usr/include/w32api/
If you want to use DirectSound also copy dsound.h to the same spot.
in the quakeforge source dir, within cygwin, type
./bootstrap
./configure --host=i386-mingw32 --build=i386-cygwin --target=i386-mingw32 --program-prefix= --with-static-plugins --disable-shared --disable-oss --disable-vorbis --disable-Werror --enable-optimize --enable-asmopt --disable-debug --enable-zlib
make
make install
--disable-Werror is needed as some versions of the DX SDK are buggy.
Go to the /usr/local/bin directory and copy the qw-* and nq-* files to your dos
quake dir
Let us know how it works for you.
NOTE: At the time of writing qw-server.exe was not working correctly. Please refrain from using it unless you are willing to fix it.
Special Note: QuakeForge supplies only our own version of the programs for Quake. To get the game data, you still need to have purchased Quake or get the shareware version from Id Software.
