Get GO work on Mac OS X

Install GO

For Mac OS X, just download pkg file and install it.

$GOPATH

Run GO code should setting $GOPATH first:

$ mkdir $HOME/Document/go
$ export GOPATH=$HOME/Document/go

or you should add GOPATH on .profile file on your home directory, so everytime your Mac OS X start will export the path already.

export GOPATH=$HOME/Document/go

Quick Test

Now, make your new GO project directory

$ mkdir -p $GOPATH/src/hello

and create hello.go file on that directory

$ cd $GOPATH/src/hello
$ nano hello.go

coding your hello.go like:

package main

import "fmt"

func main() {
	fmt.Printf("Hello, world. 你好，再见。\n")
}

ok, your can install and run that code:

$ go install hello
$ $GOPATH/bin/hello

command line show “Hello, world. 你好，再见。”

Great, it work!
