Hi,
I am getting errors, such as:
GL ERROR call: glUniform2fvARB(location, 1, values)
GL ERROR on backends/gl/GlslCode.cpp: 488: GL_INVALID_OPERATION
GL ERROR call: glUniform2fvARB(location, 1, values)
GL ERROR on backends/gl/GlslCode.cpp: 488: GL_INVALID_OPERATION
GL ERROR call: glUniform2fvARB(location, 1, values)
GL ERROR on backends/gl/GlslCode.cpp: 488: GL_INVALID_OPERATION
GL ERROR call: glUniform2fvARB(location, 1, values)
GL ERROR on backends/gl/GlslCode.cpp: 488: GL_INVALID_OPERATION
GL ERROR call: glUniform2fvARB(location, 1, values)
when running my program. This program uses RapidMind. The key part is:
/** The rendering routine, a.k.a., glutDisplayFunc() */
void Channel::frameDraw( const uint32_t spin )
{
// setup OpenGL State
eq::Channel::frameDraw( spin );
glife_glsl->update(); // need better method than glife
glife_glsl->display();
....
The display() routine calls certain OpenGL routines, leading to the error.
From the docs I find out that I should somehow define a glewGetContext(...)
function since the offending routines are called from a class other
than Channel or Window. How and were do I create this function?
Can you provide me with some hint?
Thanks,
