Are musl builds of the rust+cargo toolchain available via rustup? For running rust+cargo on Alpine.

  There's still some issues with a host musl rustc, so not yet, but we would like there to be.

    Is there a tracking bug to follow?

      My knowledge was apparently outdated! So, the bug I was thinking of was https://github.com/rust-lang/rust/issues/28667 https://github.com/rust-lang/rust/issues/28667 , which has apparently since been closed. The Alpine tracker also links to this bug: https://bugs.alpinelinux.org/issues/3949 https://bugs.alpinelinux.org/issues/3949 And in fact, https://doc.rust-lang.org/book/advanced-linking.html#linux https://doc.rust-lang.org/book/advanced-linking.html#linux has some instructions for building your own rustc in this way. I am not sure why we don't currently distribute them today, though... I will ask around. EDIT: Alex says: we don't have an issue for it specifically, no, but I think all alpine users were trying to use the llvm on the system b/c we don't work well with building an llvm against musl right now So, yeah, some small things to work out with regards to Alpine.

        I've done that once but since building rustc requires a specific nightly I'd need a glibc environment each time I want to build rustc. Replacing the glibc builds with a musl static build (not targeting but built with musl statically and no glibc requirement) would give us a single binary that works on Alpine and Ubuntu. If that's not an option I'd welcome a musl variant that's automatically installed by rustup when on Alpine or VoidLinux musl edition or any other musl linux environment.
