Additional details

lightgbm3-sys is a binding library to LightGBM, which uses CMake at least 3.28:
https://github.com/microsoft/LightGBM/blob/602528315c6d5e4ae1e8f5de106cf56cf5869b16/CMakeLists.txt#L26

Could you upgrade to 3.28+ as well?

We're using a docker container to build the docs.

You can add any ubuntu package to the package list and it would be used for new builds after the image is deployed.

i didn't check details, right now we're on ubuntu jammy in that image,

not sure if the cmake version you would need is available in jammy?

[syphar]

Just checking, jammy doesn't have it, the next LTS (noble) has it.

An ubuntu release upgrade on the crates-build-env would then be the solution, though that's a bit of work.

For anyone that might take on the work, this is the PR from last time for reference: rust-lang/crates-build-env#120

[Mottl]

Denis, thanks for the explanation!
I added CMake 3.30.2 to Dockerfiles. Please check it out:
rust-lang/crates-build-env#150

@Mottl

I'm sorry if I wasn't clear enough in my messages above.
Right now we only accept standard ubuntu packages into the builder image due to the maintenance / security burden.
So upgrading to the latest LTS is the way to solve this issue.

An alternative is to work on #315 (allow custom docker images), but my hunch is that upgrading the main build env is less work.

[Mottl]

Okay, Denis, make sense. I will try to find time to upgrade Dockerfile to 24.04

[Mottl]

This commit updates images to 24.04:
rust-lang/crates-build-env#151

[syphar]

since rust-lang/crates-build-env#168 we're now on ubuntu noble, so I assume cmake is fine too.

Feel free to ping me here or on zulip if you need a rebuild of a release.
