Qws is a standalone server itself. It does not need X or any window system.
Michail can you compile and run the same source at a PC to ensure no problems in the code? In addition you can run your application with strace to see what happens inside the application.
I’ve successfully run a qt application on a rootfs Ubuntu ARM Core, but I compiled qt from sources myself
Yes, the app runs on host fine… There is nothing in it, except a single window
I did compile the app on the host fist and had the same issue; so I decided to switch to native compile to make sure that I am not making some while compiling QT libraries.
Can you share your recipe for QT cross-compile on armhf?
