TalOrg brachte ein in meinen Augen sehr gutes Tutorial heraus, QT für Raspberry unter EGLFS zu erstellen, ich selbst setze derzeit QT 5.15.0 ein:
https://www.tal.org/tutorials/building-qt-512-raspberry-pi
Wichtig – folgende Installationen sind zusätzlich nötig zum Tutorial:
apt-get build-dep qt4-x11
apt-get build-dep libqt5gui5
apt-get install libudev-dev libinput-dev libts-dev libxcb-xinerama0-dev libxcb-xinerama0
Code für QT 5.15.1:wget http://download.qt.io/official_releases/qt/5.15/5.15.1/single/qt-everywhere-src-5.15.1.tar.xz

Swap vergrößern:
Stop the swap
sudo dphys-swapfile swapoff
Modify the size of the swap
As root, edit the file /etc/dphys-swapfile and modify the variable CONF_SWAPSIZE:
CONF_SWAPSIZE=1024
To modify the swap file, edit the variable CONF_SWAPFILE, and run dphys-swapfile setup which will create and initialize the file.
Start the swap
sudo dphys-swapfile swapon
