not sure about this. i dont know the difference between arm targets

[Myriad-Dreamin]

We ran into some errors in #884. After diff typst CI scripting with ours, I guessed we should change targets supported by cross.

this can help with rhel. but i heard that some libc function in musl is inefficient. we can observe if there is any slow down after changing this.

Besides installing the musl toolchain, testing the *-musl requires more configs, like [target.x86_64-unknown-linux-musl.linker] in .cargo/config.toml. So the cargo test fails. See the poc changes below (you might need to choose cargo / cross according to the matrix.cross variable):

      - name: Test tinymist
        run: |
-          cargo test --profile=gh-release --workspace --target ${{ matrix.rust-target }}
+          cross test --profile=gh-release --workspace --target ${{ matrix.rust-target }}

Maybe we can just use cross for testing, and get rid of dealing with the complex configs and toolchain installation...

Seems that cross-testing *-musl targets would also require vendored openssl.

Seems that build_alpine is similiar (same?) with build linux-x64 now?

[Myriad-Dreamin]

@Coekjan I've run cross test ... --features vendor-openssl, it now at least starts successfully, but it seems to be failing when downloading packages.

called `Result::unwrap()` on an `Err` value: MalformedArchive(Some("failed to create `/.cache/typst/packages/preview/tidy/0.3.0`"))

Seems that build_alpine is similiar (same?) with build linux-x64 now?

Pretty same. Now they built the same target. The only difference is in that build alpine is built in an alpine image. I suspect whether we can remove it right now, but I would rather not touching them until release 0.12.4.

[Myriad-Dreamin]

I'll close it and leave this issue for next release.
