[solved] During initialization the error "'Shiboken.ObjectType' object is not iterable" occurred

[reox]

I got now my build up and running again, unfortunately not using debian testing but only unstable.
However, I get this error message for several workbenches when starting freecad:

Is this related to the pyside version and or python3.8?

[mdhill]

I have this error in FreeCAD built from master on Fedora Rawhide. It looks like this:

https://bugreports.qt.io/browse/PYSIDE-1140

and is supposed to be fixed with Pyside2 5.14 (not in Fedora yet).

I am able to build FreeCAD master as a Flatpak without this issue, but not with the latest Pyside2. As I mentioned in another post, it builds with the Qt/KDE 5.14 runtime and Pyside2 5.12.1.

[reox]

yes, I remembering that in pyside 5.14 which is in experimental right now, I did not had the error.
However, according to some other thread there are other issues in that version.
Okay then lets wait until all the updates trickle through to sid.

[kkremitzki]

Unfortunately things are in a bit of a broken state right now until the Debian Qt 5.14 transition is complete.

[reox]

too sad, so pyside2 from sid does not work right now, for example PD can not be opened:

    cls = super().__new__(mcls, name, bases, namespace, **kwargs)

Hopefully the transition is finished soon

Recently upgraded to Fedora 32 and noticed this was broken as well.

https://bugzilla.redhat.com/show_bug.cgi?id=1750107

Well, I guess I have to use an appimage, then.

[mdhill]

@johanh, my Flatpak experience (Qt 5.14 with Python 3.7) seems to have stabilized. I just replace the line:

commit: 783e1346c7a078f5265c3f0c6a927d09a8c1fe70

with:

branch: master

https://github.com/flathub/org.freecadw ... eeCAD.yaml

[reox]

Wohoo! No more problems with pyside2 5.13.2-3
thank you @kkremitzki!

[johanh]

I've had pyside2-5.13.2-3 installed since April 29th and nothing has changed there that I know. I still have the same error. What else have changed?

Edit. OK, that's a debian version, that explains a lot (I'm on Fedora).

[reox]

Yes, that is the version which was released yesterday: https://tracker.debian.org/news/1145695 ... -unstable/

Maybe you can check which patches got added and which are missing in Fedora. There is also the other thread which links a few patches: https://forum.freecadweb.org/viewtopic.php?f=4&t=46373
