A Go compiler wrapper that speeds up the process of cross-compiling for many operating systems and architectures.

goc

A simple wrapper to run your Go builds with, supporting multiple threads for multiple builds at once.

This tool was primarily built for use with CI (such as Drone, GitLab CI, etc) and building many releases at once, but it will work wherever you want it to.

Usage

Instead of go build, you use goc. The GOOS and GOARCH env variables can be set to multiple, comma separated items.

Example source build command:

go build -o goc

Resulting command: GOOS=windows,linux,drawin GOARCH=386,amd64,arm64 goc -o goc

This will generate binaries for Windows, Linux, and MacOS, with whichever architectures are supported on each OS.

If you wish to change how goc outputs binaries (for example, output to folders for each OS) you can use the GOBINARY environment variable:

GOBINARY="{os}/{name}_{os}_{arch}"

Output

All compilation is logged to the console when complete. There is an additional output format available which contains information like os, arch, size, and hash for each file accessible by setting GOC_OUTPUT to either - (stdout) or a file name/path.

Credits

across was the inspiration for this, as well as some of the base code, however I wanted to do it a bit differently.

Caveats

Builds requiring native code/gcc are not supported, there are other programs for this.
