Ubuntu Go语言安装记录

参考地址：http://golang.org/doc/install.html

 

一些区别：

 

amd64   (a.k.a.  x86-64 );  6g,6l,6c,6a

The most mature implementation. The compiler has an effective optimizer (registerizer) and generates good code (although  gccgo   can do noticeably better sometimes).

386   (a.k.a.  x86   or  x86-32 );  8g,8l,8c,8a

Comparable to the  amd64   port.

arm   (a.k.a.  ARM );  5g,5l,5c,5a

Incomplete. It only supports Linux binaries, the optimizer is incomplete, and floating point uses the VFP unit. However, all tests pass. Work on the optimizer is continuing. Tested against a Nexus One.

 

 

安装必要依赖：

$ sudo apt-get install bison gawk gcc libc6-dev make python-setuptools python-dev build-essential

 

    安装Hg：

$sudo easy_install mercurial

 

    获取go源码：

$ hg clone -u release https://go.googlecode.com/hg/ go

 

   安装：

$ cd go/src
$ ./all.bash

 

    看到如下信息就是安装成功：

--- cd ../test
0 known bugs; 0 unexpected bugs

ALL TESTS PASSED

---
Installed Go for linux/amd64 in /home/zc/opt/go.
Installed commands in /home/zc/opt/go/bin.
The compiler is 6g.

 

    验证：

$ cat >hello.go <<EOF
package main

import "fmt"

func main() {
fmt.Printf("hello, world\n")
}
EOF
$ 6g hello.go
$ 6l hello.6
$ ./6.out
hello, world
$

go lang 更新：

$ cd go/src
$ hg pull
$ hg update release
$ ./all.bash
