how to build qt3d with Dynamic OpenGL implementation (qt5.4 -opengl dynamic)

Question

I have qt5.4 compiled with -opengl dynamic. I have tested it and the fallback works fine. Now I would like to also compile qt3d with the dynamic opengl qt libraries. Is that possible? Problem is that my building ends with linking problem below. And if I understand it correctly I should not add any opengl libraries....how can I solve this?

Answer 1

glColor4f, glColorPointer and glLightModelfv are all OpenGL 1.1 or older functions.

On Windows, it is the responsibility of OpenGL32.lib to provide those at link-time. Any parts of OpenGL newer than 1.1 on Windows have to be loaded dynamically at run-time and Qt actually does this for you if you use the appropriate wrapper classes.

In any event, to solve this simply add OpenGL32.lib to your linker dependencies.

Answer 2

The article that mentions this new Qt feature (-opengl dynamic I mean) says:

Applications that want to be dynamically switchable must always use QOpenGLFunctions and be prepared to function both on OpenGL and OpenGL ES 2.0

source

So, you can not use functions like glColor4f, glColorPointer, glLightModelfv, glBegin, etc. that have been removed from OpenGL ES 2.0
