go语言环境

操作系统:ubuntu 64bit

依次执行(这里是在/目录下执行的)
1、sudo apt-get install bison ed gawk gcc libc6-dev make
2、apt-get install python-setuptools python-dev build-essential
3、sudo easy_install mercurial
4、hg clone -r release https://go.googlecode.com/hg/ go
5、cd go/src
6、 ./all.bash
显示：
--- cd ../test
N known bugs; 0 unexpected bugs

---
Installed Go for linux/amd64 in /home/you/go.
Installed commands in /home/you/go/bin.
*** You need to add /home/you/go/bin to your $PATH. ***
The compiler is 6g.
这表示安装完毕，但还需要把一些东西加入到PATH中去


安装完成后把一下的环境变量复制到~/bashrc文件中
export GOROOT=/go
export GOARCH=amd64
export GOOS=linux
export GOBIN=/go/bin
PATH=${PATH}:/go/bin

这样直接在终端上输入6g则会显示以下提示：

gc: usage: 6g [flags] file.go...
flags:
  -I DIR search for packages in DIR
  -d print declarations
  -e no limit on number of errors printed
  -f print stack frame structure
  -h panic on an error
  -o file specify output file
  -S print the assembly language
  -V print the compiler version
  -u disable package unsafe
  -w print the parse tree after typing
  -x print lex tokens

这表示已安装成功
