Fails to install on MinGW x64

Until 2 days ago the below was working. Not sure this is a msys2/mingw or pyproj issue. First noticed on an appveyor (Visual Studio 2109) build, since confirmed locally. Need mingw x64 due to GTK+3 dependency.

Installation method/steps

• Installation method (conda, pip wheel, from source, etc…) pip install pyproj
• How did you install PROJ? Where is it installed? $ pacman -S mingw-w64-x86_64-proj C:\msys64\mingw64\bin\proj.exe
• Please provide all commands/steps you used to install pyproj and PROJ. am not sure these are all needed but…

$ pacman -Syuu  # twice if needed
$ pacman --needed -S base-devel mingw-w64-x86_64-toolchain mingw-w64-x86_64-cmake mingw-w64-x86_64-python-setuptools mingw-w64-x86_64-python-pip mingw-w64-x86_64-python-wheel mingw-w64-x86_64-proj
$ pip install pyproj

Environment Information

• pyproj version you are attempting to install 3.3.0 and 3.2.1
• PROJ version (Execute proj command and give version here.) Rel. 8.1.1, September 1st, 2021
• Python version (python -c "import sys; print(sys.version.replace('\n', ' '))") 3.9.7 (default, Nov 21 2021, 22:02:56) [GCC 11.2.0 64 bit (AMD64)]
• Operation System Information (python -c "import platform; print(platform.platform())") Windows-10-10.0.19042-SP0

My temporary solution was to use the last successful local installs wheel.

Thanks @snowman2 you pointed me in the right direction to finally find a solutions (for now)…

First of all scrap my “can not import” comment above, rookie mistake, didn’t change out of the pyproj directory first…

From what I gather: Since setuptools>=60.0.0 setuptools “includes a local, vendored copy of distutils”. Therefore the MSYS2 patched version of standard libary distutils is not used unless you make it e.g.:

SETUPTOOLS_USE_DISTUTILS=stdlib pip install pyproj

see: https://setuptools.pypa.io/en/latest/deprecated/distutils-legacy.html

Ideally the MSYS2 patches find their way into setuptools’ distutils and SETUPTOOLS_USE_DISTUTILS=stdlib becomes uneeded.

This solves my problem, thanks!
