[Mesa-dev] Wrong colors in 3D apps on big-endian systems

[Christian Zigotzky]

Hi All,

I have compiled LLVM 3.4 and Mesa 10.0.4 without any changes.

Here is the result of this test.

-> glxinfo | grep OpenGL

terminate called after throwing an instance of 'std::bad_alloc'
   what():  std::bad_alloc

-> LIBGL_DEBUG=verbose glxinfo | grep OpenGL

libGL: OpenDriver: trying /usr/local/mesa-10.0.4-llvm/lib/dri/r600_dri.so
libGL: driver does not expose __driDriverGetExtensions_r600(): 
/usr/local/mesa-10.0.4-llvm/lib/dri/r600_dri.so: undefined symbol: 
__driDriverGetExtensions_r600

Do you have any tips for me, please?
