[Mesa-users] building 8.0 on windows

[Henn, Thomas]

Hi,

I am currently using MESA 7.8.2 software renderer under Windows. But now, I would like to update to a more recent version of MESA to benefit from the faster llvmpipe. Unfortunately, I faced some problem while building MESA 8.0 using scons, regardless of llvm-support being turned on or off:


Without llvm-support (env var LLVM unset):

Does this file need to be compiled at all when building the gallium pipeline?


With llvm-support (env var LLVM set, using llvm 2.9):
> scons.bat platform=windows machine=x86 statetrackers=mesa drivers=llvmpipe winsys=gdi build=release

  Compiling src\gallium\drivers\llvmpipe\lp_setup_tri.c ...
src\gallium\auxiliary\util/u_sse.h(167) : fatal error C1083: Cannot open include file: 'tmmintrin.h': No such file or directory

When disabling SSE-support in src\gallium\include\pipe\p_config.h...
	//#define PIPE_ARCH_SSE
	//#define PIPE_ARCH_SSSE3
...we end up in the same situation as above.


Finally, I went back to MESA 7.11.2, where building the gallium softpipe under Windows works fine after some fine-tuning. But with gears.exe this pipeline is about factor 4 slower than the 7.8.2 software renderer. :-(
So I would really like to get the llvmpipe running under Windows.


Any help is very appreciated?
Thanks in advance...

Cheers,
Thomas
