feature request: install missing musl deps

[ilteoood]

If I try to use a musl target like aarch64-unknown-linux-musl, the step breaks because no musl deps are not installed.
I expect them to be installed by this action, to have an easier integration

[autarch]

Could you point me at a failed run and the config for it? I also use targets like aarch64-unknown-linux-musl with this action, and it just works for me.

[autarch]

Doh, what am I saying? It just works because I install them outside the action. Heh, I forgot that for a second. Yes, I think it would make sense to have the action do this.

Here is a broken ci if you still need it: https://github.com/ilteoood/nmt/actions/runs/10536741898/job/29197263232

So I did some further investigating, and it seems like there's no need to install the musl-tools when using cross. I realized that the tests for this action were in fact not installing that package and they all passed, regardless of whether cross was used or not.

So then I went back to one of my projects that uses this action, and I removed the step to install musl-tools entirely. It still works fine - https://github.com/houseabsolute/precious/actions/runs/10548192981/job/29221794258

Looking at the output of your action, you can see that it's complaining about a package that doesn't exist, musl-gcc.

Just to clarify further, the issue is coming from your CI setup. It's not coming from actions-rust-cross. I don't think it even got to the point of executing this action.

[ilteoood]

The CI is quite standard.
I had to insert this additional step to make it work.
https://github.com/ilteoood/nmt/blob/733f2c5afc18c917db638dd43a37b5843c6ce73e/.github/workflows/rust.yml#L39

Honestly I expect the action to install these additional deps to make musl working.

[autarch]

You didn't really respond to my point. The failure you linked is erroring out because you tried to install a Debian package named musl-gcc, which doesn't exist. Do you have a failure that shows what happens when musl-tools isn't installed?

[ilteoood]

Sorry, here is the right ci with the error: https://github.com/ilteoood/nmt/actions/runs/10536709300/job/29197193762

Aha, I see. It looks like this is only an issue when the code being compiled needs gcc. In your project, the psm crate has some C code, which leads to this error.

Can you try using the musl branch of this action?

      - name: Build binary
        uses: houseabsolute/actions-rust-cross@musl
        with:
            ...

Just replace @v0 with @musl. I think that will address the issue.

[ilteoood]

Yes, it's working fine!

I just published v0.0.14, which includes this fix.
