homebrew-musl-cross

One-click static-friendly musl-based GCC macOS-to-Linux cross-compilers based on richfelker/musl-cross-make.

brew install FiloSottile/musl-cross/musl-cross

By default it will build a full cross compiler toolchain targeting musl Linux amd64.

(It takes a while, getting a cup of coffee won't do. Going for a run might if you are more fit than me.)

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. Musl is specifically engineered to support static binaries.

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

brew install FiloSottile/musl-cross/musl-cross --without-x86_64 --with-arm-hf

You can also use --with-i486 (x86 32-bit), --with-aarch64 (ARM 64-bit), --with-arm (ARM soft-float) and --with-mips.

Only tested on macOS High Sierra.
