gnat is a toolkit for using gonative and gox to do cross-compilation in Go.
If everything is set up correctly, you should be able to cross-compile test/main.go on Ubuntu (linux) and have it run properly on Mountain Lion/Mavericks (darwin).
"Cross-linking cgo": https://groups.google.com/forum/#!msg/golang-nuts/2XoGUvBalcw/ErSWiTlO17kJ (golang-nuts)
First, clone gnat:
$ git clone https://github.com/robertkrimen/gnat.git
Then, make sure you have gonative installed. If you have go installed, you can do:
$ go get github.com/inconshreveable/gonative
Or, download a binary:
Last, run setup:
$ ./setup
Now you have a standalone cross-compiling environment in $HOME/.gnat
Create a symlink for $HOME/.gnat/gnat somewhere in your $PATH (or create an alias for it).
Run the gonative go with gnat
$ gnat go env
Use gnat compile as a compilation shortcut:
# The following are equivalent:
$ gnat compile ...
$ gnat gox -os="darwin linux freebsd windows" -arch="386 amd64" ...
The gnat go has a separate $GOPATH:
$GNAT_GOROOT/gopath
By default, gnat will include your existing $GOPATH after this one. To avoid this behavior, set $GNAT_GOPATH to null (or something else entirely):
$ GNAT_GOPATH= gnat ...
