My configuration for mesa is as follows :<br />
<br />
./configure CXXFLAGS="-O2 -g -DDEFAULT_SOFTWARE_DEPTH_BITS=31 -mavx2" \<br />
CFLAGS="-O2 -g -DDEFAULT_SOFTWARE_DEPTH_BITS=31 -mavx2" \<br />
--disable-dri --disable-egl \<br />
--with-gallium-drivers="swrast,swr" --enable-texture-float \<br />
--with-egl-platforms="" --enable-gallium-osmesa \<br />
--enable-gallium-llvm=yes --enable-llvm-shared-libs \<br />
--with-llvm-prefix="/opt/llvm/3.8.1"<br />
<br />
I have tried '-mavx -mavx2' but got the same error.<br />
