Add wheels for musl linux

[Bruceforce]

Hi, first let me thank you for your awesome work.

Is it possible to add musllinux wheel builds to pypi (PEP656)?

This would be great for all alpine users since it would simplify and speed up the installation of the libsass package.

I guess here's where the wheels are built? https://github.com/sass/libsass-python/blob/main/bin/build-manylinux-wheels

I have no experience with this, but would it be easy to adapt and run a musl container to build musl wheels? There's just no standard OS as for https://github.com/pypa/manylinux as I could see?

[asottile]

yeah I haven't seen any standardization on a base image -- we could make our own but ideally someone else would do that work lol

[toabi]

Jeah. The cryptography people have their own apparently: https://github.com/pyca/cryptography/blob/main/.github/workflows/wheel-builder.yml#L34

[asottile]

yeah they have some special requirements too like rust

Just noticed, there are musllinux images there https://quay.io/organization/pypa - here: https://quay.io/repository/pypa/musllinux_1_1_x86_64?tab=tags

@asottile I think it's quite sad to see #400 closed. It would be very useful in simplifying and speeding up docker builds.

So again, would you be open for a PR for building with https://github.com/pypa/cibuildwheel?

Hello,

I'm seconding this. Musl wheels would be great.

Unfortunately I'm not familiar with either tox or cibuildwheel, so I cannot provide a PR. However, I can confirm that libsass compiles without issues on Alpine linux, provided that gcc, g++, musl-dev, and python3-dev packages are installed (some of these may be redundant)

Hope this helps.

I have created several wheels already for musl linux because I'm building some docker images with alpine and it was taking too long to install libsass without the wheel, like 55s for only install the package
You could install it from here:
https://pypi.org/project/libsass-wheel
like:
pip install libsass-wheel
I have done it with a custom dockerfile changing versions and values but now I'm using a docker bake file to build all the needed versions in parallel, so if you need something specific like a python version with a libsass version that it's not there hit me up and I could add it
