#44 distutils not removed from setup.py?

[Sebastian Pipping]

Hi!

I see that https://sourceforge.net/p/cxx/code/451/ removed distutils from setup_makefile.py but setup.py seems to still use distutils, which is a problem with Python >=3.12. Could it be migrated to Setuptools? Thanks in advance!

Best, Sebastian

This is a contributed script, that I do not use.
Do you have a patch to it that I can use to migrate to setuptools?
Or can you use setup_makefile.py? Maybe I should delete setup.py?

Hi Barry,

I believe the Gentoo package dev-python/pycxx that brought me here uses setup.py and not setup_makefile.py. After a quick look at the Makefile that command python3 setup_makefile.py linux Makefile produced, my impression is:
- that it does not have an install target
- that the produced files obj/simple.so obj/example.so obj/pycxx_iter.so are not essential (but you tell me)
- that g++ would need to be a variable, e.g. $(CXX)
- that -g should come from $(CFLAGS) and $(LDFLAGS) to respect custom user compile flags

I may not understand the full picture yet, but so far it seems to me that setup.py is central to packaging and installation while setup_makefile.py is not. What is your understanding, how do you use setup_makefile.py and how do you install the package?

Best, Sebastian

I read how pycxx is packaged for fedora and its using setup.py - but distutils can be imported.
I'm not sure why that is working like that. Why is distutil available on Fedora?
I will investigate and update.

Note since all the setup.py does is install files there is no need to define the compiler.
PyCXX is a template library with nothing to be compiled. That happens in the projects that use PyCXX.

distutils may be importable with 3.12 in some places but upstream https://docs.python.org/3.11/library/distutils.html are clear in "deprecated with removal planned for Python 3.12" and the official docs no longer contain a page for that package for 3.12; it's officially removed with regard to CPython upstream.

I will investigate and update.

Thank you!

Understood, yes. I was referring to setup_makefile.py there and for that file, it applies.
