A Go script that could replace your Makefile.

• Automated versioning of produced binaries.
• Parallel cross compilation for all target platforms.

This script is meant to live in your project's root and used with go run make.go.

• go run make.go builds a versioned binary for the current platform.
• go run make.go -os windows -arch amd64 builds a versioned binary for a specific platform.
• go run make.go --release builds versioned binaries for all target platforms.
• go run make.go --clean removes produced binaries.

Having quite a few Go projects that produce a single binary, I was looking for a good way to have automated versioning and easily produce binaries for all the platforms that I want to support. Of course, Go can easily cross compile binaries and by using --ldflags when building we can also add a version to our produced binary. Naturally I wrote a Makefile that did all this.

But then I thought, how would this look if it was written in Go?

• Your project has a non trivial building procedure that could benefit from being expressed in robust Go code.
• You want the increased portability of Go.
• You like writing Go!

This is by no means a generic script that can be used without modifications but you can use it as a starting point. The idea is to have a make.go specific for your project that could act as your build script and possibly do other more complex stuff. The source code is public domain so if you find the content useful and want to use it as a starting point, simply copy make.go, modify it and extend it according to the needs of your project.

Now I am not suggesting that you should go and replace all your Makefiles with Go scripts. I wrote this as an experiment for my specific case, I thought the code might be useful to others and decided to share it. If a Makefile or other script gets the job done then you should use that.

• A Makefile or other script.
• Gox, my personal favorite cross compile tool.
• Mage, make.go on steroids.

If you would like to add to this basic make.go, you are welcome to do so.

The source code is public domain.
