CROSS_COMPILE.md

Cross Compiling

Cross compilation is currently described for Linux only. All the commands below rely on the host platform being linux/amd64: this is currently enforced by the Dockerfile. If you are not on a linux/amd64 system, have a look at Multi-platform builds.

Create Docker images for (cross-)compiling

Target Linux x86_64

docker build \
  --build-arg TARGET=x86-64-linux-gnu \
  --build-arg GOARCH=amd64 \
  --build-arg GOAMD64=v1 \
  --build-arg CC=gcc \
  -f Dockerfile.build \
  -t go-librespot-build-x86_64 .

Target Linux on Raspberry Pi 1 / Zero

docker build \
  --build-arg TARGET=arm-rpi-linux-gnueabihf \
  --build-arg GOARCH=arm \
  --build-arg GOARM=6 \
  --build-arg CC=arm-rpi-linux-gnueabihf-gcc \
  -f Dockerfile.build \
  -t go-librespot-build-armv6_rpi .

Target Linux ARM32 (Raspberry Pi 2 and above)

docker build \
  --build-arg TARGET=arm-linux-gnueabihf \
  --build-arg GOARCH=arm \
  --build-arg GOARM=6 \
  --build-arg CC=arm-linux-gnueabihf-gcc \
  -f Dockerfile.build \
  -t go-librespot-build-armv6 .

Target Linux ARM64

docker build \
  --build-arg TARGET=aarch64-linux-gnu \
  --build-arg GOARCH=arm64 \
  --build-arg CC=aarch64-linux-gnu-gcc \
  -f Dockerfile.build \
  -t go-librespot-build-arm64 .

Use the images built above to (cross-)compile

cd into the root of the go-librespot source code and run on of the following statements.

Target Linux x86_64

docker run --rm -u $(id -u):$(id -g) -v $PWD:/src -e GOOUTSUFFIX=-x86_64 go-librespot-build-x86_64

Target Linux on Raspberry Pi 1 / Zero

docker run --rm -u $(id -u):$(id -g) -v $PWD:/src -e GOOUTSUFFIX=-armv6_rpi go-librespot-build-armv6_rpi

Target Linux ARM32 (Raspberry Pi 2 and above)

docker run --rm -u $(id -u):$(id -g) -v $PWD:/src -e GOOUTSUFFIX=-armv6 go-librespot-build-armv6

Target Linux ARM64

docker run --rm -u $(id -u):$(id -g) -v $PWD:/src g-e GOOUTSUFFIX=-arm64 go-librespot-build-arm64
