Description
Hi Folks.
Just got cython working on Windows10 using MinGW-w64 Compiler from WinLibs. There were a couple of patches I needed to make to distutils to get things to work. I thought you may want to know about this.
[aside]. On a philosophical note, I am perplexed that the larger Python community, who is so supportive of open source, resort to using MSVC for building their Windows targets. I'll get off my soapbox now.
As you will see below, my patches are a Q&D hack to get things to work without a deeper knowledge and philosophy behind setuptool's project. I'd encourage an updating of these scripts to recent versions of the tools.
See attached, as it gets formatted incorrectly by this entry form.

Thank you very much @jon-marks for reporting this issue 😄
This seems to be related to an old version of
distutilsbeing used... I had a quick look on pypa/distutils and it seems that some of the items described in your patch were already applied.Since the latest version of setuptools will try to use a more modern (vendored) version of
distutilsby default (instead of relying on the outdated versiondistutilsthat comes in the stdlib), I believe this problem is already solved.Would you mind to check again with the latest version of setuptools?
If the problem persists the best would be opening a new issue in pypa/distutils (the bug has to be fixed there first so we can update the vendored code here on setuptools).

The
MS_WIN64needs to be defined in CPython. See python/cpython#19326Or you can define it by yourself.
msc_ver()has been updated.dllwraphas been removed.This can be closed.

Hi @jon-marks, as
imba-tjdhas previously mentioned this issue seems to be related to some changes in CPython itself (+ some of the patches have already been added to distutils). So I think I will go ahead and close this issue, but please let us know if there is still any action point from the perspective of setuptools.
