crossbuild

:earth_africa: multiarch cross compiling environments

This is a multiarch Docker build environment image. You can use this image to produce binaries for multiple architectures.

Supported targets

Using crossbuild

x86_64

$ docker run --rm -v $(pwd):/workdir multiarch/crossbuild make helloworld
cc helloworld.c -o helloworld
$ file helloworld
