https://bugs.freedesktop.org/show_bug.cgi?id=97524 --- Comment #9 from Matias N. Goldberg --- Oh I see what's happening. That's my fault. The paths to the shader files were hardcoded as absolute paths. Look for: readFile( "/home/matias/Projects/MesaRing0Bug/src/VertexShader_vs.glsl", data, FILE_BUF ); and: readFile( "/home/matias/Projects/MesaRing0Bug/src/PixelShader_ps.glsl", data, FILE_BUF ); Change the hardcoded paths, and try again. Sorry about that. -- You are receiving this mail because: You are the assignee for the bug.
