Docker image for building portable C and C++ applications for ARM Linux systems using musl libc, with the build process managed by nixcrpkgs (credit to David Grayson).
The image comes with toolchains for armv6, armv7 (both hard-float) and aarch64
pre-built.
There's a demonstrative C application in the example folder.
Also it would be a great idea to check out nixcrpkgs' README.
(proper documentation coming soon :) )
make will build and tag an image
make run will launch an interactive Bash shell
Make sure to set the DOCKER_USER environment variable for proper namespacing!
