Created attachment 813817 [details] output of emerge --info hey there, I wonder what kind of rust host does the rust team want to see running on armv7+musl in the future? right now, it does default to the glibc rust host: [build] build-stage = 2 test-stage = 2 doc-stage = 2 build = "armv7-unknown-linux-gnueabihf" host = ["armv7-unknown-linux-gnueabihf"] target = ["armv7-unknown-linux-gnueabihf"] cargo = "/usr/lib/rust/1.63.0/bin/cargo" rustc = "/usr/lib/rust/1.63.0/bin/rustc" rustfmt = "/usr/lib/rust/1.63.0/bin/rustfmt" incremental = false default-linker = "armv7a-unknown-linux-musleabihf-gcc" parallel-compiler = false [dist] src-tarball = false compression-formats = ["xz"] [target.armv7-unknown-linux-gnueabihf] ar = "armv7a-unknown-linux-musleabihf-ar" cc = "armv7a-unknown-linux-musleabihf-gcc" cxx = "armv7a-unknown-linux-musleabihf-g++" linker = "armv7a-unknown-linux-musleabihf-gcc" ranlib = "armv7a-unknown-linux-musleabihf-ranlib" llvm-libunwind = "no" crt-static = false (I removed non relevant parts for an easier read, full config.toml will be attached)

nothing changed in this area with rust-1.64, eclass (rust-toolchain) forces this because we have no installer. currently we use this as reference https://forge.rust-lang.org/infra/other-installation-methods.html so if this page does not have musl installer we force glibc host. as for the future, a variant of this https://github.com/gentoo/gentoo/pull/20727 will be implemented, currently in progress. you'd be able to set any rust triplet in make.conf, and ours will come from profiles. support for extra triplets on some profiles is also planned (like thumb-neon on arm in addition to regular host)
and ofc rust-toolchain will be reworked or obsoleted completely. it's inflexible.
