It might help to see the command line.
I have now figured out what I did wrong. I have both VS 2019 and VS 2022
installed. If I don't do anything, setuptools selects the latter, and
that doesn't match the compiler the external libs are compiled with
(and, presumably, Python itself). So, I searched for a batch file to
make setuptools use the correct compiler, and chose the wrong one,
apparently.
Adding some debug statements to msvc.py taught me that I need to call
this batch file before starting the build:
"C:\Program Files (x86)\Microsoft Visual
Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat"
(with a x86_amd64 parameter). After that, everything works as expected.
Kind regards,
Gertjan.
