Hello World

定番のHello Worldを作成してみる。まず、プロジェクトを作成する。

$mkdir -p $GOPATH/src/example/hello

いよいよ、ソースの作成だ。

package main

import "fmt"

func main() {
    fmt.Println("Hello, World!")
}

かなりシンプル。
次に実行。

$pwd
$HOME/go
$go install example/hello
$ls
bin src
$ls bin
hello
$bin/hello
Hello, World!

出来た！

We can use apt to install go.

$ sudo apt-get install golang-go

It’s easy with managing to make work space . You can use only mkdir command to make workspace.

$mkdir ~/go

And then setting workspace.

$vim ~/.bashrc
export GOPATH=$HOME/go
$source ~/.bashrc

Try to make hello world program. At first let’s make project.

$mkdir -p $GOPATH/src/example/hello

Finally programming.

package main

import "fmt"

func main() {
    fmt.Println("Hello, World!")
}

So simple. And then run.

$pwd
$HOME/go
$go install example/hello
$ls
bin src
$ls bin
hello
$bin/hello
Hello, World!

Good!
