Of course, I could be wrong, apparently it makes sense to provide either the creation of the necessary links during compilation and installation, or detection

I have not use OCL before. Did you compile FreeCAD yourself? Maybe you can find some clue here

[tiket18]

Yes, I compiled it myself, or rather, my laptop. The process was based on the link https://aur.archlinux.org/packages/freecad/ PKGBUILD and changed the link to the source from the github there, set https://github.com/realthunder/FreeCAD (This is a stable working solution). He assembled and installed all the dependencies before assembly.

I didn't see opencamlib in the PKGBUILD you linked, which is expected, as it is only a runtime dependency. Did you compiled opencamlib yourself too? Have you check the FC wiki about opencamlib I linked above? Maybe yours is not compiled with python3.

[tiket18]

Yes, the change in PKGBUILD is

cmake -DBUILD_PY_LIB = ON -DUSE_PY_3 = ON ../src -Wno-dev

resolved the issue of error. However, now another pops up and let's try to bring it to the discussion by email? w@wau.spb.ru
