Msys2 UCRT64 toolchain
Closed this issue · 4 comments
Msys2 provides now an 64bit toolchain targettting the UCRT runtimes.
This could be an alternative to the outdated msys2 m2w64-toolchain.
pacman -S mingw-w64-ucrt-x86_64-gcc
pacman -S mingw-w64-ucrt-x86_64-gcc-fortran
This is great news, thanks! :)
The current windows build setup is rather hackish, using conda's m2w64-toolchain package and manual compilation/linking commands (not through setuptools), likely linking against DLLs that are not the official ones for the individual python versions.
@carlkl The branch msys2-ucrt64 has the updated build recipe. Tests are passing. It would be great if you could take a look at some of the wheels if everything is in order (can be downloaded from here).
Seems all OK at a first glance (win10, py-3.9) - congratulations.
I propose to leave out py-3.5 and py-3.6; these are meaningless today IMHO.
Great, thanks! I think I will add a deprecation warning for py3.5, and for 3.6 as soon as it reaches EOL.
