参考文档

https://golang.org/doc/install/source
https://golang.org/doc/install/source#environment

准备

• 使用go 1.4.3编译最新的go src
  https://storage.googleapis.com/golang/go1.4.3.linux-amd64.tar.gz
  解压到go1.4
• 环境变量

export GOROOT=$(pwd)/go
export GOOS=linux
export GOARCH=amd64
export GOROOT_BOOTSTRAP=$(pwd)/go1.4

• Clone source

$ git clone https://github.com/golang/go

• 目录结构

$ tree -d -L 1
.
├── go
├── go1.4

编译

cd go/src
all.bash

测试

新文件 ./hello.go

package main

import "fmt"

func main() {
    fmt.Println("hello world!")
}

$ go/bin/go run hello.go
hello world!
