Arch Linux User Repository

Hello! I've been having trouble building this package, for about a week. The length of time makes me suspect something in my install is causing it, but I don't know what/how to find it. I've built from raw github source, and that worked fine.

Here's the output I'm getting:

testAll (TestPythonSyntax.PythonSyntaxTestCase) ... ok

    self.assertTrue(
AssertionError: False is not true : Unit of quantity material parameter ElectricalConductivity is not known by FreeCAD unit system.

I've also updated to the latest openscad (from openscad-git). Does anyone have any ideas?

EDIT: Tried it again today, and it built without problem.

Hi, I'm encountering a build error in check(), not sure if it's the package's fault or mine:

I did try removing yay's cache and the old installation, as mentioned in other comments.

Kunda, occ can't be patched here because it will need to be rebuilt with that patch. That would need to be proposed to the official occ package or submit a PKGBUILD for opencascade patched to the AUR but I don't think many people would be willing to compile occ themselves. Here is the pkgbuild for the official package: https://github.com/archlinux/svntogit-community/blob/packages/opencascade/trunk/PKGBUILD maybe submit a PR to patch the source there?

If opencascade is broken, seems like the official package deserves the patch no?

Upstream just cut a new release called 0.19. Can we use the patched OCCT repo (it has the fillet/chamfer fix in it) https://gitlab.com/blobfish/occt

Here's the patch by itself: https://gitlab.com/blobfish/occt/-/commit/ad0ba55f55b36dc957f66192c4766ace83f82b7e

It looks like installing to /usr/local is recommended against by the Arch Package Guidelines. Would you mind having freecad-git either install to /opt or split between /usr/share and /usr/lib like the official package does?

Apparently upstream FreeCAD has patches for OCCT that aren't official but fix some key issues. Lately there is a patch floating around for fixing a long standing chamfer/fillet OCC crash. I know that the OCC package maintainer for Debian is working to incorporate said patches in to their package. Perhaps we here at Arch could do the same?

Seems like it's a problem with the package. If you remove freecad-git and then reinstall it works.

Indeed it works after uninstalling the current freecad-git package. Thanks for the tip! :-)

Yes, I've tried, but didn't find anything. But they don't use Github as Bugtracker and I may be to stupid to use Mantis the right way. To be honest, it kept me from reporting from bugs in the past, since you need to report to the forums first (register there and in the bugtracker etc.) and stuff like that and it's really an endeavor to report a simple bug, it's getting frustrating fast.
