I don't see any other way than maybe stop building rest of mesa using shared glapi, but I don't know what that would break if anything

In latest update for Ubuntu Desktop 14.04.4 LTS, there is a serious problem when calling glGenFramebuffers() in a program that links both libOSMesa and libX11. Attached is a test program that can verify this. If the program is compiled with the following gcc check_glgenframebuffer.c -lGL -lX11 -lOSMesa then glGenFramebuffers() will fail when current context is set to GLX and the program will dump core upon exit. This is from gdb: Program received signal SIGSEGV, Segmentation fault. 0x00007ffff2ef930e in ?? () from /usr/lib/x86_64-linux-gnu/dri/i965_dri.so If the program is compiled with the following, then it works. gcc check_glgenframebuffer.c -lGL -lX11 This is a problem if you have a program that needs both libs such as the Open Source Video Mixer Snowmix.
