Hi Chai
Can you tell me which llvm version are you using ?
When EGL_DRIVERS_PATH is set, it should be prepended to the search
path. Did you have the variable set when running the demo?
I did make install ,hence below paths contain the same libraries.
/usr/local/lib/egl
/home/muthu/work/game/gallium/mesa-master-llvm-gcc-egl/lib/egl/
thanks
Muthukumar
