Forget my comment about RV770, I realized I'm stuck to GL3.0 with it (due to
lack of kernel support on my system).

That said, with my CYPRESS, glxinfo say:
OpenGL renderer string: Gallium 0.4 on AMD CYPRESS
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.2.0-devel
(git-7125473)
OpenGL core profile shading language version string: 3.30

But when I launch this two gl-320 tests, I got nothing (no error, no window)...

However, if I override GL version envvar, I got this:

$ MESA_GL_VERSION_OVERRIDE=3.2 MESA_GLSL_VERSION_OVERRIDE=150
./build/Release/gl-320-primitive-sprite
OpenGL Version Needed 3.2 ( 3.2 Found )

=> seems to work, I can play with the four pictures, zoom, etc.

$ MESA_GL_VERSION_OVERRIDE=3.2 MESA_GLSL_VERSION_OVERRIDE=150
./build/Release/gl-320-primitive-shading 
OpenGL Version Needed 3.2 ( 3.2 Found )
0:22(34): error: length called on unsized array
0:24(23): error: unsized array index must be constant
0:25(18): error: unsized array index must be constant

Erreur de segmentation (core dumped)

=> I got a black screen during 1 or 2 seconds and then close with a segfault.


Note that I can launch Unigine Valley (which requires GL3.2 or GL3.3 I don't
remember) without problem and without overriding the GL version envvar.
