QtOpenGL/qgl.h change between 4.7.3 and 4.8

[hml]

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,

You don't need to modify Qt headers. Just add GL/glu.h to the code that actually needs it (which is your code making use of QwtPlot3D or QwtPlot3D itself).

[hml]

Indeed, but this is a kind of a workaround for me. better than what i've done, but it still introduces an extra direct dependency of my code on that header.
I'm trying to get the proper solution implemented: is that in QtOpenGL or in qwtplot3d?

rds,

The proper solution is to fix QwtPlot3D to include GL/glu.h by itself if it needs it.

sorry to be pedantic but:
This is just a assumption: qwtplot3d is using QtOpenGL, but probably not OpenGL directly?
QtOpenGL includes the headers for the underling Opengl implementation (Mesa in the linux box I have and win in a win box I have)

I'd still be curious to see why qt changed their header between 4.7.3 / 4.8.0

is there a subversion access or similar?

If QwtPlot3D is complaining about missing GLU headers then obviously it uses GLU and not only QtOpenGL.

My totally wild guess would be that they stopped using it.

There is Git.
