Describe the bug Simple project runs under Linux but fails under Windows.

To Reproduce Steps to reproduce the behavior:

  2. Start it inside QtCreator (under cmdline there is not output)
  3. Aborted

Message when running in debugger: grafik

Traceback when running in debugger: grafik

Platform information (please complete the following information):

Additional context This is my first opengl project. It may be that i miss something.

The message "... Please instantiate the QApplication object first ..." from the app output above is only displayed under Windows - not under Linux.

The windows environment is running under Proxmox (qemu vm system).

Here the project: demo-map.zip

The *.pro file may have to be changed. This includes the LIBS and INCLUDEPATH variables which point to the QMapLibre installation.

Does qemu have OpenGL acceleration? Do other Qt example apps work fine?
