The systemwide LIBDRM shared-libs (see /etc/ld.so.conf.d/x86_64-linux-gnu.conf) have a higher position in the ldconfig-cache and considered at rank #1 before mine. Solve this by renaming xorg.conf -> a-local-xorg.conf (YUPP, the filename matters!). I have also built the Intel XORG video driver and executing... LIBGL_DEBUG=verbose LIBGL_DRIVERS_PATH=/opt/xorg/lib/dri glxgears ...now uses i965_dri.so and intel_drv.so from my /opt/xorg installation. Unfortunately, the generated libGL.so from gles3 mesa GIT tree is a bit "buggy" (segfaults in FFX and unity-3d is unusable). Handling of libGL.so version in Ubuntu is done a bit uncomfortably via /usr/lib/x86_64-linux-gnu/mesa/ld.so.conf file. But this is a different story... Attached are my build-scripts with a lot of comments. So, I hope I catched all problems with building LIBDRM/MESA with LLVM/CLANG. A big thank-you to Edwin for the vital help. - Sedat - $ cat /usr/lib/x86_64-linux-gnu/mesa/ld.so.conf /usr/lib/x86_64-linux-gnu/mesa $ cat /usr/lib/x86_64-linux-gnu/mesa/ld.so.conf_myXORG-1st /usr/lib/x86_64-linux-gnu/mesa /opt/xorg/lib
