Build from source breaks after upgrade from Qt 6.4.3 to 6.5.0 about linuxdeployqt

Are you building linuxdeployqt from source? What happens if you use the linuxdeployqt AppImage (continuous build) provided on GitHub Releases?

Are you building linuxdeployqt from source?

Yes, I am building linuxdeployqt from source using clang++ 10 with Qt 6.5 under dockerized Ubuntu Focal inside my CI.

What happens if you use the linuxdeployqt AppImage (continuous build) provided on GitHub Releases?

The published AppImage works without any issues. The drawback is that it is only provided for the x86_64 (amd64) CPU architecture. The reason I was building linuxdeployqt from source in the first place is to support other architectures such as aarch64 (arm64) and armv7 (arm32) in my CI. That being said, the symptoms described in this bug report are present for all CPU architectures with Qt 6.5. I can even reproduce it on my x86_64 laptop with Qt 6.5.2.

This probably is because linuxdeployqt has never really been ported to Qt6. It is a Qt5 application and has only ever been tested to be compiled with Qt5.

While that is certainly possible, I suspect that this is merely caused by change of qmake's configuration language. Out of curiosity, I tried running it in project generation mode using qmake6 -project, and got somewhat sane .pro file out of it. The only drawback was that I had to manually cherry-pick files that belong to tests and examples. You may want to consider it in a future release/PR.
