cargo install error on Alpine -- nix related?

When running cargo install ironbar on my machine, I got this error:

error: could not compile `ironbar` (bin "ironbar") due to 3 previous errors
error: failed to compile `ironbar v0.15.1`, intermediate artifacts can be found at `/tmp/cargo-installgmhXjZ`.
To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.

I then proceeded to clone the repo and build directly (cargo build --release), and it worked! I am using Alpine Linux, so not sure if there is some weirdness going on there. But just wanted to bring it to your attention. Looking forward to playing with the bar.

System information:

• Distro: Alpine Linux Edge
• Compositor: labwc
• Ironbar version: 0.15.1

Hey, the nix crate refers to *nix rather than Nix(OS). Under the hood it binds to the platform's libc library.

Am I right in thinking alpine uses musl rather than glibc? That might be the cause here, although I've no idea why it'd work installing it one way and not the other when it's compiling on your system either way.

[rgilton]

I see the same errors when trying to build on Fedora 40. Building with rust 1.78.0.

[JakeStanger]

Well I guess that rules out musl then. I've just tried in a Fedora docker container from blank and it built fine, so not sure what's going on there.

I'll have a poke around in the nix crate and see if I can see any reason that fs feature flag would get turned off.

[JakeStanger]

For some reason Rust is resolving a newer version of the nix crate than what was in the lockfile for you guys, which had breaking changes. I've updated to the latest version in the above PR which also fixes the breaking changes, so this should be resolved once that's merged.
