Re: mesa3d with llvm support

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
