After several years I'm going to give another try to Buildroot :-)
This time I built an environment for RPi4+Qt5.
Surely I missed some packages because if I try to run a QML application I
got the following error:
> Could not find DRM device!
> Aborted
Instead a Qt5 console application seems to run fine.
I attach my .config file. Hope you can give me some hints!
Best regards
Andrea

Hope you can give me some hints! You seem to have a RPi4-64bit config, trying to run mesa vc4? Sorry, not owning an RPi4 for testing, but for the RPi3 you need to enable the right Device-Tree-Overlay in your config.txt, e.g. (see the following two links for earlier discussion [1], [2]): dtoverlay=vc4-fkms-v3d This may or may not work as RPi3 is VC4 and RPi4 is VC6 ([3]), but Gentoo claims to have RPi4 running with mesa ([4], [5])... Alternatively your can try RPi4-32bit and enable rpi-userland/BR2_PACKAGE_RPI_USERLAND instead of mesa...
