invalid use of incomplete type ‘PyInterpreterState’

I got this trying to compile 0.18.4:

Code: Select all

   75 |     PyObject *modules = interp->modules;

I'm sorry, but what kind of system information would help here?

Here's some information:
Arch Linux
Python 3.8.2
CMake 3.17.0

This helps, Thanks.

FreeCAD 0.18.4 was not ported to 3.8.2 and probably other newer libs (OCCT for example), because you are on ARCH you have the bleeding edge libs.
I suggest you try with the master branch.
We are in a feature freeze and hopefully will be releasing 0.19 next month. I also don't think I've seen CMake 3.17 yet.

Building master worked. Thanks.

Great. Out of curiosity what version of QT5 do you have?
