coreaudio-sys 0.2.5 failed to build

[mitchmindtree]

Crate name:

coreaudio-sys 0.2.5

Build failure link:

https://docs.rs/crate/coreaudio-sys/0.2.5/builds/264503

Additional details:

The crate used to fail as expected when publishing previous versions, however with 0.2.5 I attempted to fix the Cargo.toml metadata to select the correct target for building coreaudio-sys docs for x86_64-apple-darwin. The crate seems to build successfully for the same target in our github action, but fails on docs.rs.

I've opened an issue at RustAudio/coreaudio-sys#40 with more details/thoughts. Any advice on how we might go about fixing the build would be greatly appreciated!

A big difference from your CI build is that docs.rs is always cross-compiling from linux, you are only able to control the target not the host. So there would need to be a way to get the required header files on the Ubuntu image used for the build.

Ahh I see!

It looks like we might benefit from solving RustAudio/coreaudio-sys#38 and updating our docs-check action to cross-compile from Ubuntu to match the docs.rs approach.

Thanks for the tip!

docs.rs is always cross-compiling from linux,

This would be good to document, a lot of our build failures have been coming from this.

@mitchmindtree are you still planning to work on this?

[mitchmindtree]

I have no plans related to this at the moment, though I believe it is still an issue for coreaudio-rs and coreaudio-sys. I do still have a WIP PR at coreaudio-sys which I'd be more than happy for someone to take over RustAudio/coreaudio-sys#38. I don't mind if you wish to close this due to inactivity. I'll leave a note at the PR recommending someone take over.

@jyn514 one thing that might be useful is if you could link to the CI/script that docs.rs uses to cross-compile for macOS from Linux. This way we can check the coreaudio-sys CI matches, uses the same versions/SDK, etc.

[jyn514]

@mitchmindtree you can replicate it by running docs.rs itself locally: https://forge.rust-lang.org/docs-rs/add-dependencies.html#testing-the-image

There's also an unofficial script, but it's not tested: https://github.com/Nemo157/dotfiles/blob/master/bin/cargo-doc-like-docs.rs
