Supporting Qt 6 - What's needed?

ppenguin · December 19, 2023, 9:30pm

Does that mean if I rebuild pyside with the “correct” options and depend on it this error should be gone?

yes soqt is not needed for pivy compilation, also freecad has no dependency on soqt. Afaik freecad has included its own version of quarter.

Is anyone actually using FreeCAD with Qt6? I’m testing git version on Debian 12 and it crashes here and there.

Loading Arch WB ends with:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
<class 'Base.FreeCADError'>: Unknown C++ exception raised in activateWorkbench('ArchWorkbench')

Loading Draft WB ends with crash:

That’s just selecting WB from combobox on freshly started FreeCAD. There are dozens other ways to crash it and this is not a complaint, but an explanation why I’m asking a question at the beginning of this post.
Yesterday’s FreeCAD_weekly-builds-35720-2024-01-23-conda-Linux-x86_64-py310.AppImage, which is built against Qt5, is working quite fine.

Now looking closer at above backtrace, Draft WB is importing Qt5 Widgets. Verified by removing libQt5Widgets.so.5:
