Description Mario Blättermann 2015-02-19 10:56:10 UTC
Description of problem:

I've compiled a small game with needs OpenGL. It starts, but is obviously unable to handle the provided GLSL versions:

$ tetzle
QGLShader::compile(Vertex): 0:1(10): error: GLSL 1.30 is not supported. Supported versions are: 1.10, 1.20, and 1.00 ES

QGLShader::compile(Fragment): 0:1(10): error: GLSL 1.30 is not supported. Supported versions are: 1.10, 1.20, and 1.00 ES

QGLShader::compile(Vertex): 0:1(10): error: GLSL 1.30 is not supported. Supported versions are: 1.10, 1.20, and 1.00 ES

QGLShader::compile(Fragment): 0:1(10): error: GLSL 1.30 is not supported. Supported versions are: 1.10, 1.20, and 1.00 ES

QGLShader::compile(Vertex): 0:1(10): error: GLSL 1.30 is not supported. Supported versions are: 1.10, 1.20, and 1.00 ES

QGLShader::compile(Fragment): 0:1(10): error: GLSL 1.30 is not supported. Supported versions are: 1.10, 1.20, and 1.00 ES

When I launch it with --graphics-layer=21 or --graphics-layer=15, then it works as expected. I've contacted upstream and get an answer:
"You built a fully functional binary package. Your Mesa is reporting that it supports a higher version of GLSL than it actually does, and Tetzle is auto-detecting that. Tetzle has runtime support for different versions of OpenGL, no compile-time options."
See https://github.com/gottcode/tetzle/issues/3

mesa-libGL-10.4.3-1.20150124.fc21.x86_64

Comment 1 Mario Blättermann 2015-06-14 15:41:19 UTC
It seems to be rather a problem with the video driver... But because I don't need this for the review ticket previously depending on this bug report, I close it now.
