General Building C Python module for AC Python 3.3.5 version

styinx · Apr 12, 2021

Hey,

I've been trying to compile a custom C-API Python module for AC's 3.3.5 Python and using it in-game. The module compiles successfully and I get the finished *.pyd that I can import. Using the module in a local terminal works fine, however, using it in AC leads to a crash (importing is fine though).

Did anybody else try this before, or has somebody a tip I haven't tried yet?

Some more information:

I installed MSVC 10 with the Windows 7 SDK. Therefore, the binary should have been created with the correct compiler (as described here https://wiki.python.org/moin/WindowsCompilers).
By logging inside the custom module I know that importing the module and instantiating class objects of the module works fine.
The repository with the code can be found here (https://github.com/styinx/ACLIB_plugin).

Cheers, and thanks for any input.

For anyone interested:

I solved the problem myself, however, I am not sure what was the cause.
Removing the garbage collection flag 'Py_TPFLAGS_HAVE_GC' and the function pointer to the destructor from the 'PyTypeObject' description did the trick.
Be careful, this might lead to a memory leak!
