I'm having almost the same problem trying to build it via crossdev (i.e. "i686-pc-linux-gnu-emerge --buildpkgonly dev-lang/rust"): Finished release [optimized] target(s) in 1364.29 secs Copying stage1 rustc from stage1 (x86_64-unknown-linux-gnu -> x86_64-unknown-linux-gnu / x86_64-unknown-linux-gnu) Copying stage2 std from stage1 (x86_64-unknown-linux-gnu -> x86_64-unknown-linux-gnu / x86_64-unknown-linux-gnu) Copying stage2 test from stage1 (x86_64-unknown-linux-gnu -> x86_64-unknown-linux-gnu / x86_64-unknown-linux-gnu) Copying stage2 rustc from stage1 (x86_64-unknown-linux-gnu -> x86_64-unknown-linux-gnu / x86_64-unknown-linux-gnu) Copying stage2 compiler (x86_64-unknown-linux-gnu) Build completed successfully in 1:33:07 >>> Source compiled. >>> Test phase [not enabled]: dev-lang/rust-1.19.0 >>> Install rust-1.19.0 into /usr/i686-pc-linux-gnu/tmp/portage/dev-lang/rust-1.19.0/image/ category dev-lang !!! dobin: build/i686-unknown-linux-gnu/stage2/bin/rustc does not exist !!! dobin: build/i686-unknown-linux-gnu/stage2/bin/rustdoc does not exist There seem to be two separate problems here - rust's build system ignores cross compilation (it always builds for the host target), and the ebuild uses hardcoded platform triples (causing the dobin error).
Can you try this with a recent 1.26 version? Support for arm should be much better now.
Going to call this fixed, please reopen if you still see issues.
