Failed to install on musl system (aipine linux)

[gspe]

I'm trying to install rust-analyzer on alpine linux docker but the installation fail with this error:

error: failed to compile `rust-analyzer v0.1.0 (/rust/rust-analyzer/crates/rust-analyzer)`, intermediate artifacts can be found at `/rust/rust-analyzer/target`

Caused by:

This is a rustc limitation, see rust#40174.

Proc macros are really convenient in chalk for deriving traits like Fold, so I don't think we'll be removing them. Also, I think rust-analyzer itself makes use of proc macros as well, so removing their usage from chalk wouldn't solve your problem.

Unfortunately, I'm really not sure there's anything for us to do here. As @detrumi said, seems like a rustc issue.

Sorry 😟
