Error compiling rgbd

[du-xinyi]

• OpenCV => :4.8.1:
• Operating System / Platform => :ubuntu20.04:
• Compiler => :g++:

In cmake, select with_opengl=on，my qt version is 6.5.3. The following error occurred at compile time

when calling cmake try to add -DOpenGL_GL_PREFERENCE=LEGACY

Yes.... A straight-forward solution is just to Turn OFF rgbd... Thank you ...

I made experiments with Ubuntu 18.04, 20.04 and 24.04. Only Ubuntu 24.04 provides QT6 package (6.4.2). All the combinations were built just fine and passed tests. Looks like your QT build is not complete.
