[BUG?] FreeCAD 0.19 - Draft WB - Wrong number or type of arguments for overloaded function 'SoMFString_setValue'.

[icewalker]

After upgrading to FreeCAD 0.19 I cannot get any tools working from the Draft WB.

Not able to assess where is yhe issue, (too) old Python lib maybe, something else... Any help will be much appreciated.
Note: these issues where not present with the previous freeCAD 0.18.x version I was using (which disappeared after the update).

• Have installed the 'freecad' package using 'apt' from the stable repository (reference at the bottom of this post).

• Regarding the python lib/pip, I do not know how to update them.

• I have both python 2.7.17 and 3.6.9 installed.

When loading the Draft WB I get the following report:

Code: Select all

04:58:06  Persistent toolbars: Snapper toolbar not managed.

    SoMFString::setValue(char const *)
    SoMFString::setValue(SoMFString const *)

When I try the ShapeString by clicking on the 'S' icon once the WB is loaded (anyhow with the 'pivy' bug trace), the following is reported:

Looks like a packaging issues. Try using the AppImage and report back if you can recreate the issues.

Tested with FreeCAD_0.19-24291-Linux-Conda_glibc2.12-x86_64.AppImage
ShapeString creation, conversion to Sketch and pocket'ng are possible again.
Tried to fix the packaging issue to get back to the more repository related usage (which is a personal preference), so far without success.
Thank you Kunda1!

Glad to hear the workaround worked.

It may have something to do with your Qt version.

I use AppImage also and not any more using the Fedora version
