librespot/contrib/Dockerfile

# Cross compilation environment for librespot
# Build the docker image from the root of the project with the following command :
# $ docker build -t librespot-cross -f contrib/Dockerfile .
#
# The resulting image can be used to build librespot for linux x86_64, armhf and armel.
# $ docker run -v /tmp/librespot-build:/build librespot-cross
#
# The compiled binaries will be located in /tmp/librespot-build
#
# If only one architecture is desired, cargo can be invoked directly with the appropriate options :
# $ docker run -v /tmp/librespot-build:/build librespot-cross cargo build --release --no-default-features --features "alsa-backend"
# $ docker run -v /tmp/librespot-build:/build librespot-cross cargo build --release --target arm-unknown-linux-gnueabihf --no-default-features --features "alsa-backend"
# $ docker run -v /tmp/librespot-build:/build librespot-cross cargo build --release --target arm-unknown-linux-gnueabi --no-default-features --features "alsa-backend"
#
