------------ BUILD FINISHED ------------
To use wxPython from the build folder (without installing):
 - Set your PYTHONPATH variable to /var/tmp/portage/dev-python/wxpython-4.2.1-r2/work/wxPython-4.2.1-python3_11.
 - You may also need to set your (DY)LD_LIBRARY_PATH to /var/tmp/portage/dev-python/wxpython-4.2.1-r2/work/wxPython-4.2.1-python3_11/build/wxbld/gtk3/lib,
   or wherever the wxWidgets libs have been installed.

Fixed by dropping Python-3.12 support.

Upstream issue: https://github.com/wxWidgets/Phoenix/issues/2104

I noticed your ebuild is heavily out of sync to the gentoo ebuild. Maybe you want to rebase it and send some of your changes as PR into gentoo.

Also if I understand https://projects.gentoo.org/python/guide/migration.html#migrating-to-pep-517-builds right: The wxpython ebuilds need to be converted to setuptools what would provide distutils functions to compile with python 3.12. https://bugs.gentoo.org/909973

I noticed your ebuild is heavily out of sync to the gentoo ebuild.

Do you really need that extra testing functionality?

Maybe you want to rebase it and send some of your changes as PR into gentoo.

I've tried it before and it's a waste of time.

The wxpython ebuilds need to be converted to setuptools what would provide distutils functions to compile with python 3.12.

The upstream build system needs to be converted, not just the ebuild. Read the upstream issue I linked.

As long as their build system depends on distutils, it cannot be built using 3.12.
