Steve Dower  added the comment:

Yeah, this will be our fault.

Someone is looking into automatically generating the .def file so that this 
stops happening. Last time we tried that there was a lot of pushback because 
"too many APIs will become stable", but this time I think we're just going to 
force those devs to care for their APIs properly.

(I'm blanking right now on who was working on this... anyone remember?)

This looks like a bug to me. While 
https://github.com/python/cpython/commit/2ff58a24e8a1c7e290d025d69ebaea0bbead3b8c
 added it to the header, it did not add it to 
https://github.com/python/cpython/blob/master/PC/python3dll.c which is required.

[issue42415] python3.lib in Python3.9.0 Windows distribution does not contain PyObject_CallNoArgs symbol

[David Hewitt]

New submission from David Hewitt :

I'm unsure if this is a packaging error or a misunderstanding by me.

I'm trying to link a binary on windows with Py_LIMITED_API set. According to 
https://www.python.org/dev/peps/pep-0384/#linkage I _think_ I'm supposed to be 
linking against python3.lib (instead of python39.lib).

However my build fails because the PyObject_CallNoArgs symbol is not present in 
python3.lib

I see that the symbol is indeed present in python39.lib

Is this a misunderstanding on my part? I was under the impression that 
python3.lib will only contain symbols available in the limited api, and that 
(since 3.9) PyObject_CallNoArgs is part of the limited api.
