Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

I don't understand why meson wants to find distutils; meson itself should already be the right build backend...

../meson.build:20:15: ERROR: <PythonExternalProgram '$PREFIX/bin/python' -> ['$PREFIX/bin/python']> is not a valid python or it is missing distutils

A full log can be found at $SRC_DIR/forgebuild/meson-logs/meson-log.txt

Looks like mesonbuild/meson#7702 is the relevant upstream issue. I haven't actually sat down and digested the discussion there, though.

[pkgw]

Looks like adding setuptools as a dep works around the issue, but then gobject-introspection itself depends on distutils, so we might need to add it as a runtime dep as well.

[h-vetinari]

Yeah, but adding setuptools should not be necessary as meson itself is an equally (or even more) capable build system. For example, numpy & scipy build without issue on 3.12 with meson and without setuptools

[pkgw]

Based on that Meson issue, my understanding is that Meson currently requires distutils for its Python support to work at all, though — apparently it's one of the few modules that Meson needs. From the Numpy build log, setuptools is getting pulled in as a dep in the 3.12 build, so it might be working coincidentally.

[pkgw]

The Linux / Python 3.10 failure above looks spurious. The remaining Python 3.12 failures appear to be because gobject-introspection itself requires distutils, which I think at least could be worked around by adding a runtime dep on setuptools?
