New submission from Dan Yeaw <d...@yeaw.me>:
I am using the mingw-w64-x86_64-python3 in MSYS2 on Windows to package a PyGObject app. When I try to pip install the app, I am getting errors about the VC 6.0 isn't supported. It looks like setuptools is trying to patch distutils msvc. The msvc9compiler module in distutils uses a get_build_version function to get the version of MSVC on the system. This version of Python 3 is compiled with GCC 8.3.0 so the function doesn't find the "MSC v." prefix and returns version 6. Here is the full error: $ pip install -e .

I am also glad to help submit a PR if I can have some guidance on the best approach. ---------- components: Distutils messages: 339520 nosy: danyeaw, dstufft, eric.araujo priority: normal severity: normal status: open title: Distutils VC 6.0 Errors When Using mingw-w64 GCC type: compile error versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36539> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
