I recently upgraded my distro (Linux Mint 20) and have just realised that FreeCAD is now broken - it may be related or it may not.
I build and run FreeCAD locally from Git.

When starting FreeCAD, the report view shows:
Part.so: cannot open shared object file: No such file or directory

I thought I'd just rebuild it however when I do that, I get:

[ 58%] Built target Web

Any ideas what is wrong?

Just a guess.
Could you 'make clean' then try to 'make' again' ?

Thanks, I'd just tried that and was about to post when I spotted your reply - it took ages to build but it worked

Could delete this thread perhaps?

I think we can keep it. I think many users that compile themselves tends to only "incrementally" compile without never cleaning.
So maybe they can found something useful here.
