go windows 32位环境搭建

go windows 32位环境搭建

网上讲go语言编译环境搭建的文章不少了，搭建环境本身也相对简单，本文主要是提供一个可下载的地址，因为刚开始我找了好几个地址都没能下载到想要的版本，

这个地址是刚试过能访问的：http://code.google.com/p/go/downloads/list

Downloads页面有下面这些go语言开发包，这里我们选择下载go1.0.3.windows-386.zip：

go1.0.3.darwin-386-signed.pkg	go1.0.3.darwin-386.pkg	go1.0.3.darwin-386.tar.gz
go1.0.3.darwin-amd64-signed.pkg	go1.0.3.darwin-amd64.pkg	go1.0.3.darwin-amd64.tar.gz
go1.0.3.freebsd-amd64.tar.gz	go1.0.3.linux-386.tar.gz	go1.0.3.linux-amd64.tar.gz
go1.0.3.src.tar.gz	go1.0.3.windows-386.msi	go1.0.3.windows-386.zip
go1.0.3.windows-amd64.msi	go1.0.3.windows-amd64.zip

下载下来之后go环境的配置比较简单：

1 解压压缩包到go工作目录，如解压到E:\opensource\go\go，解压后的目录结构如下：

E:\opensource\go\go
├─api
├─bin
│ ├─go.exe
│ ├─godoc.exe
│ └─gofmt.exe
├─doc
├─include
├─lib
├─misc
├─pkg
├─src
└─test

2 增加环境变量GOROOT，取值为上面的go工作目录

3 Path环境变量中添加";%GOROOT%\bin"，以便能够直接调用go命令来编译go代码，至此go编译环境就配置好了

4 测试go编译环境，启动一个cmd窗口，直接输入go，看到下面的提示就是搭建成功了

E:\opensource\go\go>go Go is a tool for managing Go source code. Usage: go command [arguments] The commands are: build compile packages and dependencies clean remove object files doc run godoc on package sources env print Go environment information fix run go tool fix on packages fmt run gofmt on package sources get download and install packages and dependencies install compile and install packages and dependencies list list packages run compile and run Go program test test packages tool run specified go tool version print Go version vet run go tool vet on packages Use "go help [command]" for more information about a command. Additional help topics: gopath GOPATH environment variable packages description of package lists remote remote import path syntax testflag description of testing flags testfunc description of testing functions Use "go help [topic]" for more information about that topic.

5 编译helloworld测试程序，go语言包中test目录带有helloworld.go测试程序，直接调用"go build helloworld.go"就生成了"helloworld.exe"可执行程序，运行一下这个程序看到了我们期望的hello,wolrd。

E:\opensource\go\go\test>go build helloworld.go E:\opensource\go\go\test>helloworld.exe hello, world E:\opensource\go\go\test>
