 Posted: Tue May 28, 2024 8:01 am Post subject: Versions of dependencies in ebuilds |
 |
|
Hello,
I am writing an ebuild for new Nicotine+ version.
I have searched the release notes and checked the minimal versions of dependencies and a pair of questions arose:
1. If minimal python version is 6, then should PYTHON_COMPAT be 6..12, or is it some gentoo policy to keep just three versions?
2. what is [introspection] version here?
x11-libs/gtk+:3[introspection]
I have found the version that newest release needs. Should I replace introspection with it? |

Minimum python version is 3.6, not 6, you're cover here, 3.12 is already available for Gentoo. There's no python 6. Also, there already is a nicotine+ ebuild available in the main tree. You should be able to just copy and version bump it in your local repo. Version bump means you just rename the file to contain the new version.
EDIT: just tested it, it compiled fine.

That means gtk+ needs to have introspection use flag enabled.

Georgi,
let me start by clarifying that I am writing an ebuild based on what is already available.
The ebuild in the repo is old and I want to upgrade it.
You are right about the Python version, I spelled it wrong.
What I wanted to ask about Python is if for the new ebuild I should stick to the current 10..13 versions, or to go with upstream's 6..13.
Do you know if we have a policy on it? |

setan,
Stable python is :3.10. Older versions are masked or removed, so there is no useful purpose in permitting python 3.9 and older.
If you permit python 3.13 you may hit bugs due to python 3.13 being immature.

I don't know. Objectively speaking, the earliest we have in tree is 3.8 and it doesn't seem to be masked or anything. I would go with it, it's covered by the minimum requirements, in the same time there aren't many people who still run older versions of python an a well maintained installation, if any at all. Also you're doing it for personal use so it doesn't matter really, for as long as it works.
Best Regards,
Georgi |

Specifying versions older than 3.10 in your PYTHON_COMPAT is ignored by the python eclass. You can list it if you want but it does nothing.
This is actually a good thing since Gentoo doesn't support dependencies for 3.6 either, so if you actually did support 3.6 in your ebuild then it wouldn't be able to resolve dependencies for 3.6
Older python versions are kept around and freely available for use as an *interpreter*, not as a target for building other packages with. This is helpful e.g. to python developers that want to use python 3.8 with virtualenvs and in tox or other testing tools for their own projects that still support Ubuntu Bionic.
I'm one of those python developers  so it's very nice that Gentoo does this. |
