In Python 3.12, the distutils package is removed

In Python 3.12, the distutils package is removed: https://github.com/python/cpython/issues/92584

Currently, you can still get import distutils by installing setuptools, so one workaround would be to simply document that setuptools is needed. I’ve confirmed that this is sufficient to make the Fedora Linux package compatible with the Python 3.12.0a5 pre-release.

Migrating from distutils to setuptools would also be pretty straightforward.

• In configure.ac, from distutils import sysconfig can become from setuptools import sysconfig import sysconfig.
• In pymusic/setup.py.in, from distutils.core import setup can become from setuptools import setup.
• In pymusic-old/setup.py, from distutils.core import setup and from distutils.extension import Extension can be replaced by from setuptools import Extension, setup.
• In pymusic/pymusic.pyx and pymusic/pybuffer.pyx, the # distutils: language = c++ comments should still be correctly interpreted by Cython even without distutils.
• In pymusic/tests.py, the replacement of distutils.version import LooseVersion is a little less straightforward. The easiest thing to do would be to introduce a test dependency on packaging: https://packaging.pypa.io/en/stable/version.html

Rather than from setuptools import sysconfig, I suggest using the sysconfig module from Python standard library. In the case of this configure.ac script, distutils.sysconfig.get_python_inc() can be replaced by sysconfig.get_path('include').

Many thanks!

This should now be fixed in commit d49d1a2e. I will create a new release + new Debian packages within a couple of days.

The directory pymusic-old remains there only for reference and is not used.
