Hi David,
I am using the Catalyst 12.1 driver which I think is the latest available.
I've managed to track the error down to the following two lines in Program.cpp
(both throw OpenGL errors).
Line 798 _extensions->glGetActiveUniformsiv( _glProgramHandle,
uniformIndex.size(),&(uniformIndex[0]), L_UNIFORM_ATOMIC_COUNTER_BUFFER_INDEX,
&(bufferIndex[0]) );
and
Line 818 _extensions->glGetProgramiv(_glProgramHandle,
GL_ACTIVE_ATOMIC_COUNTER_BUFFERS,
reinterpret_cast<GLint*>(&activeAtomicCounterBuffers));
As far as I can figure out, the problem is the two enums, which are only valid
for OpenGL 4.2+. My video card reports:
OpenGL version string: 4.2.11399 Compatibility Profile Context
OpenGL shading language version string: 4.20
so it should be handle these calls. The NVidia card (where osgsimplegl3 works)
is a much older OpenGL 3.2 compatible card.
Any further ideas are most welcome!
Thanks,
Roland
