Bug 909973 – dev-python/wxpython: needs to use PEP517 build (DistutilsNonPEP517Build)

• Product: Gentoo Linux
• Status: CONFIRMED ---

[Description Michał Górny 2023-07-08 06:56:48 UTC]

This package still uses the legacy eclass code paths.  These paths are deprecated and pose a significant maintenance cost.  Please update the package to use PEP517 build mode.  For more information, please see the Python Guide, particularly; https://projects.gentoo.org/python/guide/migration.html#migrating-to-pep-517-builds

[Adding this comment en-masse, sorry for the noise, but it's important.)

1. Please take particular care to check file diffs before/after, possibly using `iwdevtools`. Keep a particular eye out for e.g. config files now missing from /etc and instead being in /usr/lib/python*/site-packages, etc.

2. Please make sure to do the migration in a new revision in ~arch, partly because of 1.

The conversion to setuptools in this ebuild is important for python 3.12.

I have not tested the gentoo ebuild with python 3.12 but I think the output would look similar.

------------ 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.

I'm trying to update the ebuild but it seems not all needed is built after approximately 2 hours.
