Thanks for the patch, now works correctly the example "qt5_openglwindow".

I also tried two more examples of qt5_gui module (qtbase/examples/gui), 
the rasterwindow and analogclock. To include these examples in the 
compilation mechanism of Genode I relied on the example 
"qt5_openglwindow". Both examples compiled correctly, but do not run as 
they should. I tried it on Qemu with pbxa9 using the foc  kernel.

You have any idea what is happening?
Thank you
