# Many instructions from: https://github.com/japaric/rust-cross

# 1. Need C cross toolchain + libraries:
# sudo apt install gcc-arm-linux-gnueabihf libc6-dev:i386 *armhf
# See: https://github.com/japaric/rust-cross/blob/1573dbba707e588bd2715934670dffc480bc3da2/.travis.yml#L26

# 2. Cross-compiled std crate:
# rustup target add armv7-unknown-linux-gnueabihf

# 3. Build the GameShell image (requires Docker installed)
docker build -t sunjay/caves-armv7-unknown-linux-gnueabihf-sdl2 -f docker/armv7-unknown-linux-gnueabihf/Dockerfile docker

# Build the project for that platform
# https://github.com/rust-embedded/cross
# cargo install cross
cross build --target=armv7-unknown-linux-gnueabihf --verbose $*

# Now the target directory (or just the executable) can be copied over and run
