    Thank you for your tutorial, I have spent the previous three weeks trying to find a way to cross compile qt for my raspberry pi 4 (I am using the raspberry pi os lite) I followed all the steps and I got this error can you please help me

    I just wanted to test it on the raspbian buster lite os to see if the problem comes from the raspberry pi os lite
    https://downloads.raspberrypi.org/raspbian_lite/images/raspbian_lite-2020-02-14/ I installed the 2020-02-13-raspbian-buster-lite.zip and didn't work also I got the same error..

    Am I doing something wrong? I really do need to cross compile Qt for my end of studies internship and I tried several methods that didn't work on an os with no x server, https://github.com/PhysicsX/QTonRaspberryPi/blob/main/qt5.14.2onRaspberrypi this one worked but the eglfs was not enable for raspberry I had to use the framebuffer linuxfb to test projects and I couldn't even import QtQuick.Studio.Components 1.0 can you please help me ?
