FreeCAD dependency probably outdated

Dear Guix people,

I have checked FreeCAD on several machines and get the same error.

To reproduce:

- guix install freecad

- Open FreeCAD

- Create new document

- Select 'Draft' workbench

This produces an error:

'<built-in function SoFieldContainer_getField> returned a result with an exception set'

The backtrace and also as some forums suggest (e.g., https://forum.freecad.org/viewtopic.php?t=74156)that the issue is the outdated 'python-pivy'. The dependency version in python-xyz.scm is 0.6.5 released Jan 12, 2020 where latest release 0.6.8 is from Aug 25, 2022.

I have tried to build newer version of 'python-pivy' but I hit some errors that I do not understand how to fix. The errors from build log among other things tell that it 'Could not find a package configuration file provided by "Qt5Core" with any of the following names: Qt5CoreConfig.cmake qt5core-config.cmake'.

Could somebody with more knowledge about building freecad help or give some suggestions how can I define latest 'python-pivy' (assuming the outdated package causes the 'Draft' workbench crash).

repository URL: https://git.savannah.gnu.org/git/guix.git

commit: 1dbe492b993a7629df3b35146ce0272b52913776

I looked at the 'python-pivy' issue again today. I was able to build 'python-pivy' from git with:

git clone https://github.com/coin3d/pivy

cd pivy

guix shell -D python-pivy -- python3 setup.py build

Examining build log of the former and comparing to the build log of standard 'guix build python-pivy --load-path=/my/python-pivy.scm' I found some differences in paths passed as arguments to the 'swig' command called by 'setup.py'. Specifically the 'swig' command is different in its last '-I' argument

guix shell -D python-pivy -- python3 setup.py build:

-I"/gnu/store/1k54m72p12h0lkqa9iicfknydawdfrbm-profile/include"

guix build python-pivy --load-path=/my/python-pivy.scm

-I"/gnu/store/ivbbmgrvhdc46p2ywx1x2zsmal3x0z5n-soqt-1.6.0-1.fb8f655/include"

Both paths have 'Inventor' dir in it but the former has a lot of symlinks to the Coin but the later has only one symlink to Qt dir. I think this is why there was a buildsystem patch commented as "respect Coin3D include directory". It does not work for the latest python-pivy and this is where I stuck. Do not understand why with 'guix shell -D python-pivy -- python3 setup.py build' works whereas 'guix build python-pivy --load-path=/my/python-pivy.scm' does not and how can I fix/path.

Moreover it seems that there is another issue already. I just did guix pull ('guix describe' -> guix bfc6143) and now freecad can not even be installed. This time 'python-pyside' dependency is not building. Bellow is python-pyside-2-5.15.10 build log:

phase `go-to-source-dir' succeeded after 0.0 seconds

starting phase `fix-qt-module-detection'

error: in phase 'fix-qt-module-detection': uncaught exception:

Can someone, please, check if this is indeed a new issue or freecad can still be installed?

I'm unable to build python-pivy with the suggested changes. Here is the

actual diff I used:

I get lots of errors like these:

I've also tried building pivy 0.6.8 against an updated soqt (1.6.2) but get similar errors. Any idea what needs to be

upgraded here to make pivy build?
