setuptools required to build, but is not instralled by default on newer Debian

[VanessaE]

I recently reinstalled my system in order to upgrade to Debian testing/"Trixie" (as "Bookworm" was gradually degrading from "stable" to "stale" and some stuff I rely on had quit working, as is so often the case with Debian), and for whatever reason, Printrun didn't want to build, until I found that setuptools doesn't get installed by default.

A simple python3 -m pip install setuptools after doing the requirements.txt step resolved it, after which setup.py build_ext --inplace was able to do its job normally.

This suggests to me that setuptools should either be added to requirements.txt, or setup.py should explicitly check for and install it when needed. Or at the very least, the need for it should be mentioned in the README.

Since Debian testing doesn't give the OS itself a version number, I'll have to just say that at the time this happened (a bit less than two weeks ago), I had just finished the OS install maybe an hour or two prior.

This system uses Python 3.13.2.

Here's the full log of a successful build/install, with setuptools added in where I installed Cython, for reference:

Hi @VanessaE, thanks for reporting this. Could try installing the "new way" and see if setuptools gets installed? I mean running (venv) $ python -m pip install . instead of the old python3 -m pip install -r requirements.txt. This "new way" should install both setuptools and Cython on its own because it uses pyproject.toml which lists both as build dependencies.

[VanessaE]

Nope, that method is also not sufficient to bring in setuptools or Cython.

Thanks. That's weird. It was supposed to work like that. I'll try to reproduce this and come back to you.
