How To Build for Arm

[amadeus]

Steps to reproduce

1. ./configure --with-features=huge --enable-terminal --enable-rubyinterp --enable-python3interp --enable-perlinterp --enable-cscope
2. make
3. Attempts to build, but eventually I get this error: ld: symbol(s) not found for architecture arm64, right after a long chain of stuff like this:

Undefined symbols for architecture arm64:
  "_PyBytes_AsString", referenced from:
      _DoPyCommand in if_python3.o
  "_PyBytes_AsStringAndSize", referenced from:
      _StringToLine in if_python3.o
      _StringToChars in if_python3.o
      __ConvertFromPyObject in if_python3.o
  "_PyBytes_FromString", referenced from:
      _ConvertToPyObject in if_python3.o
      _DictionaryListKeys in if_python3.o

      _OptionsItem in if_python3.o
  "_PyBytes_FromStringAndSize", referenced from:
      _ConvertToPyObject in if_python3.o
      _VimToPython in if_python3.o
  "_PyCapsule_GetPointer", referenced from:

  "_PyCapsule_New", referenced from:
      _convert_dl in if_python3.o
  "_PyDict_GetItemString", referenced from: // etc etc

Expected behaviour

App should be able to build successfully.

Thank you for an issue,

Could you check which architecture of Python do you have installed?

As logs show I suspect you have x86_64 Python and it definitely won't link with arm64

Ahh yup, that is most certainly it. I have some python3 packages installed via nix that are not arm based. I will look into that and see if I can rectify it. Thanks for note!
