Crosscompile QT6 for pi4 in full screen (eglfs)

ben80

Hello, i am trying to crosscompile qt6 for the raspberry 4 (raspberry OS bookworm) to run a qt application with hardware acceleration in full screen mode (without desktop). This worked fine for my rpi2 and qt5.
I am following this guide (Link) but it is targeted for X11 window systems.

My issue:
My config.summary tells me, that the rpi specific backend is not configured properly.
For qt5 this was very relevant. Is this still the case for qt6? How could i go on?

QPA backends:
  DirectFB ............................... no
  EGLFS .................................. yes
  EGLFS details:
    EGLFS OpenWFD ........................ no
    EGLFS i.Mx6 .......................... no
    EGLFS i.Mx6 Wayland .................. no
    EGLFS RCAR ........................... no
    EGLFS EGLDevice ...................... yes
    EGLFS GBM ............................ yes
    EGLFS VSP2 ........................... no
    EGLFS Mali ........................... no
    EGLFS Raspberry Pi ................... no
    EGLFS X11 ............................ yes

Thanks a lot for any help
Ben

Check the config.log file to see why it was not configured properly. Or run configure script with -v parameter.
