Use cargo-auditable with cross?

[NobodyXu]

Is it possible to use cargo auditable with cross for cross compilation?

[Shnatsel]

I've used it with cargo build --target=something-other-than-native-target and it worked fine. I haven't tried it with cross specifically. Try it and let me know if it works!

FWIW sccache required some fixes to work with cargo auditable. If cross doesn't Just Work, I'm happy to accept fixes for supporting cross or to help investigate why it fails.

Running cross with cargo-auditable gives me subcommand not found error:

❯ cargo auditable cross b --release
error: no such subcommand: `cross`

        View all installed commands with `cargo --list`

While running cross b --release directly works as intended.

Yeah, that doesn't work because you're calling it cross not cargo cross.

Hmm. I think the best way forward is to file an issue on the cross issue tracker about potentially supporting cargo auditable. Basically a call to cargo auditable sets RUSTC_WORKSPACE_WRAPPER to itself, and saves the arguments it received into an environment variable so that the wrapper then recovers it. That's basically it as far as integration is concerned.

It's also possible to use cargo auditable as a drop-in replacement for cargo, that might come in handy.

It seems that cargo-cross does not exist and the cross crate only provides binary cross.

We've identified 2 ways to do today in the linked Cross issue:

1. Use a custom docker image which overrides cargo with cargo auditable
2. Use a pre-build hook to install cargo auditable

Additionally support for Cargo subcommands is in the works in cross, which should make it even easier.

I'm going to go ahead and close this since using with cross is possible, but feel free to reopen if there's more to discuss.
