Install docker and docker-compose

Docker Docs

Clone Repo

git clone https://github.com/casonadams/cross-compiler-rs.git

Usage

Build base images

Buid base image

cd cross-compiler-rs
docker-compose build lede

Copy source to Projects

• Repos can be cloned here
• Projects dir is a shared volume so any editor can be used to edit the code. Then run the docker container to build when ready.

Start container

Start docker to build rust application

docker-compose run lede

Build rust application for mipsel musl

cd ~/Projects/example
cargo build --release --target=mipsel-unknown-linux-musl
mipsel-openwrt-linux-strip target/mipsel-unknown-linux-musl/release/<bin_file>
