OBS on CentOS 7

[Spastek]

Not sure if this is the right forum or not but hopefully if not you guys can point me in the right direction.

I have installed OBS on CentOS 7 which required that I update the cmake from 2.8.11. to 2.8.12 (currently running 3.3.2) which was a pain in of itself.

After getting cmake to update, I've hit another wall when I actually run OBS. I get the following error when attempting to run OBS

When I run LIBGL in verbose mode I get the following

Currently using NVidia Geforce 770 with 352.41 Driver version.

I'm able to run other openGL applications with no issues. Seems to be just OBS. Any insight would be helpful.

This was the top result on google so I figured I would share my findings here.

I encountered the above error running CentOS 7 under VMWare Fusion. OpenGL version was 2.1, verified via: glxinfo | grep "OpenGL version"

Updating to the 4.8 kernel enabled OpenGL 3 support, and OBS was able to start properly.

Yep, you need OpenGL 3.2 or later to run OBS on Linux.
