Right, so is there anything we can do to build OSMesa for 14.04.x users to resolve this? Or do we say sorry, don't mix OSMesa with OpenGL, hopefully it will be better in the next LTS? IOW do you see this moving towards "In Progress" or "Won't Fix"?
I completely understand the reasoning in bug #1424059, and maybe there is no other way to resolve this in trusty without apt/dpkg versioned Provides. I certainly don't have any ideas how to fix this. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1551028 Title: glGenFramebuffers fails when linked with OSMesa AND X11 Status in mesa package in Ubuntu: Incomplete Bug description: Hi. 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.
