It works here. It could be some compatibility issue with your LLVM version, but I am not familiar with the code there. You might want to file a bug report. I do notice one thing weird in the EGL log below. <div class="im"> > These are my export variables.: > -------------------------------------------------- > export > LD_LIBRARY_PATH="/home/muthu/work/game/gallium/mesa-master-llvm-gcc-egl/lib" > export EGL_LOG_LEVEL="debug" > export GALLIUM_DRIVER="llvmpipe" > export > EGL_DRIVERS_PATH="/home/muthu/work/game/gallium/mesa-master-llvm-gcc-egl/lib/egl/" > > Here iam sending the log messages. > ------------------------------------------------------------ > [muthu@localhost opengles1]$ ./gears_x11 > libEGL debug: EGL search path is /usr/local/lib/egl </div>When EGL_DRIVERS_PATH is set, it should be prepended to the search path.
