Cross compiling for raspberry pi 4 problem
-
I just cross compiled QT on ubuntu for my raspberry this is the code that I followed https://github.com/PhysicsX/QTonRaspberryPi/blob/main/qt5.14.2onRaspberrypi .
I think that I did something wrong because when I created a project and tried to test it on my raspberry I had this error and the system crashed
Could not queue DRM page flip on screen HDMI (invalid argument)there is some problem with eglfs (the project worked with
./speedometer -platform linuxfbhow to fix this and also I have this error while triyng to compile a new project
I am new to Qt can someone please explain to me what is wrong ? do I need to reinstall it ?

and

QT_QPA_EGLFS_KMS_ATOMIC=1solved my problem.

@Diracsbracket sorry for my late relay it was the first time that I post in this forum and I didn't get any notification so I thought that nobody answered ! actually I deleted the qt version because I couldn't fix it and I got other problems I couldn't even
import QtQuick.Studio.Components 1.0it does not exist, so I tried to uninstall all of it and tried again from the beginning ! I am still stack :( ! couldn't make it work :( please if you have any good documentation on how to cross compile qt on an os without a desktop version please share it with me ! and also which configuration should I make in my os to make qt work (I created an os with buildroot which is very minimal )
