Hi Michael,
Have look at Ulrich's post:
I will submit the fix for it...
Just out of curiosity what is your graphics card and driver, 480gtx driver
296.10?
Cheers

Coming to think of it, I believe the whole block should check if
atomicCounterMap is not empty. It does not need to be called if
GL_UNSIGNED_INT_ATOMIC_COUNTER is supported but not used.
<code>
if (_extensions->isShaderAtomicCounterSupported() &&
!atomicCounterMap.empty()) {
std::vector<GLint> bufferIndex( atomicCounterMap.size(), 0 );
std::vector<GLuint> uniformIndex;
</code>
Cheers,
/Ulrich

Subject: [osg-users] glGetActiveUniformsiv error
With the latest update I get an error in
void Program::PerContextProgram::linkProgram(osg::State& state)
There error is in
_extensions->glGetActiveUniformsiv( _glProgramHandle, uniformIndex.size(),
&(uniformIndex[0]),
GL_UNIFORM_ATOMIC_COUNTER_BUFFER_INDEX,
&(bufferIndex[0]) );
The size of uniformIndex is 0!!
Try and run osgsimplegl3!!
