I have cross-compiled Qt 5.14 on raspberry pi 4 using ubuntu 18.04 I just followed al the steps of this tutoriel https://www.youtube.com/watch?v=TmtN3Rmx9Rk&t=2538s

the code is just right here https://github.com/PhysicsX/QTonRaspberryPi/blob/main/qt5.14.2onRaspberrypi

and after creating RaspberryDemoQml to test

~/Desktop/build-RaspberryDemoQml-RaspiQt-Release$ ls
main.o  Makefile  qrc_qml.cpp  qrc_qml.o  RaspberryDemoQml

I also checked the file

~/Desktop/build-RaspberryDemoQml-RaspiQt-Release$ file RaspberryDemoQml 
RaspberryDemoQml: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0, BuildID[sha1]=79b829d37b5493d859eab8a5d3534b2d6dfb6d5f, not stripped

and everything seems to be okay

and I did scp RaspberryDemoQml [email protected]:/home/pi

I tried to execute it on my raspberry ./RaspberryDemoQml

But I got this error

Could not queue DRM page flip on screen HDMI (invalid argument)

and the system crashed

I am actually working on raspberry pi os lite and I don't want a desktop version

Can someone explain the error for me please ? is that because I don't have GUI ? do I have to install Xorg ? or It's a QT issue
