This repo contains a single Dockerfile for building an image capable of cross-compiling for ARM targets using musl libc. The final container includes rustc + standard libraries and cargo.

Standard Docker build applies:

docker build --tag arm-musl-rust .

Start the build and go enjoy a quality 8 hours of sleep.

To use the container, change to the root directory of the Rust code you want to build. Then execute:

docker run -v $(pwd):/source --rm -it arm-musl-rust

From there, the usual Rust cross-compiling rules apply. The following targets are available:

arm-unknown-linux-musleabi
arm-unknown-linux-musleabihf
armv7-unknown-linux-musleabihf

GCC cross compilers for the architectures are in /usr/local and are named:

arm-linux-musleabi-gcc
arm-linux-musleabihf-gcc
armv7-linux-musleabihf-gcc
