Description Dennis Schridde 2017-04-09 00:41:33 UTC

Static linking of Rust binaries is supported on the x86_64-unknown-linux-musl target only: https://doc.rust-lang.org/book/advanced-linking.html

It would be great if Gentoo would (optionally) build Rust with support for the x86_64-unknown-linux-musl target.

Please note that this is not related to bug #598892.

I think that PR covers dynamic linking with x86_64-unknown-linux-musl?  And in any case, Gentoo needs to support the additional target, before this can be used.

Building a rustc that can target musl requires having musl available for linking libstd, so that would make dev-lang/rust depend on sys-libs/musl. Unfortunately, sys-libs/musl conflicts with glibc.

not going to implement this as an additional target for ::gentoo rust, however on musl hosts rust works nowadays (rust and rust-bin) and can emit static libraries.
while not very convenient, you can have a musl chroot with rust-bin, it will produce static binaries by default.
