Hi,

There have been changes in this file, between 4.7.3 and 4.8.0
1 of them is that

# include <GL/glu.h>

was removed, under linux.

A 3rd party library qwtplot3d header includes QtOpenGl and expects to find symbols declared in glu.h

I manually added it back to 4.8.0 and the compilation succeeds.

Any QtOpenGL writers care to comment?

Very unwilling to have a different headers from std qt 4.8

regards,
