Hi,
I am porting over my OpenGL application written with Qt 4.8.1 to Qt 5.0, the latter of which I compiled from source for both x86 and x86-64. The application uses OpenGL 2 and GLEW. I am developing on Windows 7 ×64.
After changing over the #include-s, I ran into problems. It seems that “QT_OPENGL_ES_2” is defined, so that in the file “qtbase/src/opengl/qgl.h”, it will eventually include “qtbase/src/3rdparty/angle/include/gles2/gl2.h”. The problem is that this file defines a number of things that GLEW already defines (e.g. “GLintptr”). In that first file, something similar happens with “typedef GLfloat GLdouble;”
All this seems very strange, as I don’t (think?) I’m having Qt use OpenGL ES. After some groveling around in the sources and my compiler, the culprit seems to be “qtbase/src/corelib/global/qconfig.h”, lines 124-128, which will define QT_OPENGL_ES_2 when it’s not available, even if QT_NO_OPENGL_ES_2 has been defined. Something similar happens immediately above for QT_OPENGL_ES.
So . . . any thoughts?
Thanks.
Ian
