Meson not working within MSYS2 environment

[radioactiveman]

Describe the bug
Meson does not work for me within a MSYS2 environment. Any command fails with an error about a wrong Python installation.
According to the documentation, Meson should work after installing the MinGW Python. What am I missing here?

To Reproduce
Run the commands below in a MinGW shell (MSYS2 MinGW 32-bit):

$ pacman -Syu
$ pacman -S meson
$ pacman -S mingw-w64-i686-python3
$ meson --version
ERROR: This python3 seems to be msys/python on MSYS2 Windows, which is known to have path semantics incompatible with Meson
ERROR: Please install and use mingw-w64-i686-python3 and/or mingw-w64-x86_64-python3 with Pacman

$ command -v python
/mingw32/bin/python

$ python --version
Python 3.8.7

Expected behavior
Meson should use the Python which works as exptected.

System parameters

• Windows 10 1809
• Python 3.8.7
• Meson 0.56.0

Hello @lazka, @nirbheek,

are you able to reproduce this?
What else needs to be done besides installing mingw-python?

Thanks.

[lazka]

you need to install mingw meson and be in a mingw shell. https://packages.msys2.org/base/mingw-w64-meson

[radioactiveman]

$ pacman -S mingw-w64-i686-meson mingw-w64-i686-pkg-config

Thanks, Meson is working fine now. 👍

So in other words, MSYS2 is not supported by meson at all? Is there no way to run meson in a build process from an MSYS2 shell?

No, everything should work. If something doesn't, file a bug and feel free to ping me.
