[solved] QOpenGLFunctions with specific version on Windows with Qt 5.3
I opened the OpenGLWindow example and replaced the QOpenGLFunctions with QOpenGLFunctions_3_2_Core/Compatibility. As a result, I am getting the following error message:
"error: C2504: 'QOpenGLFunctions_3_2_Compatibility' : base class undefined"
Upon further investigation, it turns out that the problem lies here:
#if !defined(QT_NO_OPENGL) && !defined(QT_OPENGL_ES_2)
Apparently, the condition is false and the class is not being defined. How do I fix this problem?
This seems to be a Windows specific problem. I have managed to get equivalent code to run under MacOSX10.9. I wonder what is going on?
Hi, welcome to devnet.
Did you use the ANGLE version of Qt by any chance? It only supports OpenGL ES 2 set and not the higher core profiles.
Hm, I don't think I installed the ANGLE version, at least not consciously. I simply used the default Qt online installer of the community edition. How do I verify I have the right version installed?
Go to the Qt installation directory and run MaintenanceTool.exe. Select Packages and expand the Qt 5.3 branch. You will see about a dozen of different versions there. See which one you have selected. The msvc* ones without "OpenGL" at the end are ANGLE builds.
Spot on, that was it. Thank you for the help!
