z_README.md

To build a full cross compiler targeting musl Linux amd64, type this and wait. (A cup of coffee won't do. Going for a run might if you are more fit than me.)

brew install --HEAD https://gist.github.com/FiloSottile/01d2bbfaf63ae1b6e373e6bc874fefc6/raw/musl-cross.rb

You can then use x86_64-linux-musl- versions of the tools to build for the target. For example x86_64-linux-musl-cc will compile C code to run on musl Linux amd64.

The "musl" part of the target is important: the binaries will ONLY run on a musl-based system, like Alpine. However, if you build them as static binaries by passing -static as a LDFLAG they will run anywhere.

Other architectures are supported. For example to get a Raspberry Pi cross-compiler use:

brew install --HEAD https://gist.github.com/FiloSottile/01d2bbfaf63ae1b6e373e6bc874fefc6/raw/musl-cross.rb --without-x86_64 --with-arm-hf

You can also use --with-i486 (x86 32-bit) and --with-arm (ARM soft-float).
