[Mark_m]

Hello
Two Problems:
1.
I have updatet to Ubuntu 22.04

Word size of OS: 64-bit

Appimage startet but no functionality works. Can't create a new document or can't open a Part.

2.
After update to Ubuntu 22.04
Freecad from Ubuntu installed with apt.
Freecad works but the Path toolbar dont work.

OS: Ubuntu 22.04 LTS (ubuntu:GNOME/ubuntu-xorg)
Word size of OS: 64-bit

Version: 0.19.
Build type: Release

OCC version: 7.5.1
Locale: German/Germany (de_DE)

A lot of errors comes:

17:09:43 Traceback (most recent call last):
File "/usr/share/freecad/Mod/Path/PathScripts/PathJobGui.py", line 139, in attach
self.axs = coin.SoType.fromName('SoAxisCrossKit').createInstance()
File "/usr/lib/python3/dist-packages/pivy/coin.py", line 491, in createInstance
return _coin.SoType_createInstance(self)
<class 'SystemError'>: <built-in function SoType_createInstance> returned a result with an exception set

17:09:43 SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats
17:09:43
The above exception was the direct cause of the following exception:

17:09:43 Traceback (most recent call last):
17:09:43 File "/usr/share/freecad/Mod/Path/PathScripts/PathJobGui.py", line 1367, in Create

return self.openTaskPanel('Stock')
17:09:43 File "/usr/share/freecad/Mod/Path/PathScripts/PathJobGui.py", line 186, in openTaskPanel
self.showOriginAxis(True)
17:09:43 File "/usr/share/freecad/Mod/Path/PathScripts/PathJobGui.py", line 162, in showOriginAxis
self.switch.whichChild = sw
17:09:43 File "/usr/lib/python3/dist-packages/pivy/coin.py", line 3998, in __setattr__
field = self.getField(name)
17:09:43 File "/usr/lib/python3/dist-packages/pivy/coin.py", line 3873, in getField
return _coin.SoFieldContainer_getField(self, name)
17:09:43 SystemError: <built-in function SoFieldContainer_getField> returned a result with an exception set

Many Thanks in advanced

I am now getting this same error today after having a week of my setup working on 22.04.

[adrianinsaval]

are you using the version from the default ubuntu repos? IIRC those were broken although I don't remember if it had these same errors, try with the ppa version if it's available for 22.04 otherwise run the appimage with the workaround mentioned in the known os specific issues post

Code: Select all

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6 ./FreeCAD_weekly-builds-27936-Linux-Conda_glibc2.12-x86_64.AppImage

(adapt the filename of the appimage to the one you have and check that the libstdc++ path is correct for your system)

This is a problem that has started with Py 3.10 and must be handled by pivy

17:09:43 SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats

For more details see: https://bugs.python.org/issue40943

There also was a PR for FreeCAD but we have removed the '#' from PyArg_ParseTuple to avoid to deal with the PY_SSIZE_T_CLEAN.

looo has fixed the pivy code to handle this:
https://forum.freecadweb.org/viewtopic. ... 77#p563177
https://github.com/swig/swig/issues/2150
https://github.com/coin3d/pivy/issues/88
https://github.com/coin3d/pivy/pull/91

So, obviously the pivy version in the Ubuntu repo is broken and the package maintainer should fetch the fixed sources from upstream.

there is a new release which has python3.10 support:

The appimage works now!
Thanks a lot!

Yes.
But I prefere the appimage. Unfortunality the appimage was broken since some time, as fallback I use the Ubuntu repos.
Now I will use the appimage again


Many thanks for the fast helping!!
