Go语言开发环境搭建

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！
