I have cross compiled Qt5.12.3 on my Ubuntu machine for raspberry pi 3B+ as the target device. Everything is fine and my application is cross-compiled successfully.
The issues is that after building the app, the app runs but never opens. The qt creator just shows this message: "Starting /home/pi/myApp..." but the app never shows up.
It seems the application process is running on the target device. Also I can run the app from my rasp terminal. I think there should be some problem with displaying the app in my Ubuntu remotely.
Any help will be appreciated. thanks.

Unfortunately I had stopped the trials because of other priorities. Therefore I do not know a cure yet.What OS build did you install on RPi?

Your app will output the ui to the rpi´s connected display. It won´t show up on your remote development device.
