I am trying to use glew and Qt together, which worked fine with Qt 4.7. In 4.8 however it does not seem to be possible anymore. Including glew before QtOpenGL yields:
@/usr/include/QtOpenGL/qglfunctions.h:46:2: warning: #warning qglfunctions.h is not compatible with GLEW, GLEW defines will be undefined [-Wcpp]
/usr/include/QtOpenGL/qglfunctions.h:47:2: warning: #warning To use GLEW with Qt, do not include <QtOpenGL> or <QGLFunctions> after glew.h [-Wcpp]
and it later does not find functions like 'glUseProgram'. If I turn the includes around, the result is:
@/usr/include/GL/glew.h:84:2: error: #error gl.h included before glew.h
/usr/include/GL/glew.h:87:2: error: #error glext.h included before glew.h
I cannot find much information about how it would still be possible to use them together. I have a rather large codebase of platform independent c++ opengl code and I always used Qt for window/context creation etc on desktops. The dependency on glew is not necessary, if I could still call all gl* functions normally c style. The documentation of QGLFunctions indicates how to achieve this for the paintGL method only, which is obviously not enough.
Is there still a way to use glew and Qt 4.8 together? Or to drop glew as explained above?
