[Mesa-dev] How to compile MESA7.9 to support EGL_MESA_screen_surface.

[xiaoxiaomuyu]

demo3.c,  ./a.out
libEGL warning: failed to create DRM screen
libEGL warning: use software fallback
EGL version = 1.4
EGL_VENDOR = Mesa Project
EGL_MESA_screen_surface is not supported

./configure --prefix=/usr --enable-gallium-llvm --enable-gallium-i915
--with-dri-drivers=i915 --enable-gallium-i965=disable
--enable-gallium-radeon=disable
     EGL:             glx  ???? It's right. seems i don't need it. Thanks.
