By the way, you should be able to reproduce these runtime errors by building r600g with the llvm compiler and enabling egl support in mesa: --with-gallium-drivers=r600 --enable-r600-llvm-compiler --enable-gallium-egl --with-egl-platforms=x11,drm And running one of the egl demos, like eglgears, from the mesa-demos package. -Tom > > 2.
