Cross-compiling a Buffalo application

Just like another Go application, you can cross-compile a Buffalo application. This means it's possible to develop your app on a Mac, and compile it for a Linux target on your Mac.

GOOS and GOARCH

The Go toolchain supports cross-compilation out of the box. You just need to provide the GOOS and GOARCH env variables.

GOOS sets the target OS (e.g. linux, windows, etc.)
GOARCH sets the target CPU architecture (e.g. amd64, 386, etc.)

You can find the list of supported targets here: https://golang.org/doc/install/source#environment

Examples

Build for AMD64 Linux

$ GOOS=linux GOARCH=amd64 buffalo build

Build for ARM64 Linux

$ GOOS=linux GOARCH=arm64 buffalo build

Build for i386 Windows

$ GOOS=windows GOARCH=386 buffalo build
