go语言 windows 32位编译环境搭建
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C:\go，解压后的目录结构如下：
C:\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
注：
set GOROOT=C:\Go
setx GOROOT "%GOROOT%" -m
setx path "%path%;%GOROOT%\bin" -m
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
C:\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，源码见"附一 helloworld.go"，
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。
C:\go\test>go build helloworld.go
C:\go\test>helloworld.exe
hello, world
C:\go\test>
附一 hello.go
package main //独立运行的文件必须是package main
import "fmt"//实现格式化的I/O
func main(){
fmt.Print("Hello,Wrold!\n");//打印输出Hello,Wrold!
}
附:编译环境批处理文件及hello.go源代码！
