Cant build due to can't find crate for zerofrom_derive

[euzu]

I do not use directly zerofrom its added as a dependency from another crate.
When I try to compile with cross I get this strange error:

Any clue why this is happening ?

Can you share what you are attempting to build?

Ideally, also your output of cargo tree -e features

Building this crate locally shows no such issues for me.

[euzu]

yes it is this project

https://github.com/euzu/tuliprox/actions/runs/18169428034

[Manishearth]

Yeah, I don't know what's going on here. The crate build does work successfully above that.

I'm inclined to think this is a bug in the musl build; potentially the zerofrom_derive proc macro crate isn't being built correctly

[euzu]

Strange thing is, it worked yeaterday.

[Manishearth]

Potentially a rustc/cargo bug?

[euzu]

I dont know, it runs on local with the same settings but not on github.

I found the reason, the build cache was corrupted.
