I did a very simple Ogl program. When I compiled it against the system provided Opengl libraries, it worked as intended, with direct rendering.

However, when I link it against my own, built from scratch Mesa , it only gets indirect rendering.

So, what is necessary to my custom built Mesa to provide direct rendering?

Edited with configure's output:

  • good question, what did the configuration step of Mesa say that it supported in backends? Commented Sep 1 at 13:40
  • @MarcusMüller What would be a backend here? Commented Sep 14 at 23:14
  • DRI + the individual userland side of the GPU driver in mesa Commented Sep 15 at 16:45
  • @MarcusMüller. If I understood correctly what you meant, it says: "Driver: dri". I edited the question with configure's output. Commented Sep 26 at 14:21
