Hi
It compiles on Linux/Mac but on Windows I get the errors below.
Many thanks
Michael

Sounds like you didn’t include all needed OpenGL headers.
On Windows you will need an extension loader like glew.

Thanks now I did:

#include <GL/glew.h>

in init function:

GLenum err = glewInit();
if (GLEW_OK != err)
{
/* Problem: glewInit failed, something is seriously wrong. */
fprintf(stderr, "Error: %s
", glewGetErrorString(err));
}

but still get tons of as below. What to do?
Many thanks
Michael

Try defining GLEW_STATIC while building and try rearranging your linking order, building on windows can be sensitive to the order the OpenGL/glew related libs are added to the linker.

Yes I do link: opengl - glu - glew32s and defined static. Still the same with Eclipse/MingW on Vista. But I got the very same working in VC2008. Any more ideas? Thanks.
