GO语言使用自定义包

Windows系统下C语言中使用自定义包的方法：

首先明确GOPATH的路径，执行go env | findstr GOPATH

C:\Users\CHORDER>go env | findstr GOPATH
set GOPATH=C:\Users\CHORDER\go

C:\Users\CHORDER>

接着在GOPATH目录中创建相应的自定义包，这里定义一个example包，并创建两个源码文件src1.go和src2.go，源码内容如下：

/* C:\Users\CHORDER\go\src\chorder.net\example\src1.go */

package example

import "fmt"

func init(){
        fmt.Printf("\nchorder.net/example/src1.go init() has been called.")
}

func Src1(){
        fmt.Printf("\nchorder.net/example/src1.go Src1() has been called.")
}

/*C:\Users\CHORDER\go\src\chorder.net\example\src2.go*/

package example

import "fmt"

func init(){
        fmt.Printf("\nchorder.net/example/src2.go init() has been called.")
}

func Src2(){
        fmt.Printf("\nchorder.net/example/src2.go Src1() has been called.")
}

编写代码调用这两个包中的方法：

packge_test.go

package main

import "chorder.net/example"

func main(){
    example.Src1()
    example.Src2()
}

执行结果：

>go run packge_test.go

chorder.net/example/src1.go init() has been called.
chorder.net/example/src2.go init() has been called.
chorder.net/example/src1.go Src1() has been called.
chorder.net/example/src2.go Src1() has been called.
