ubantu上编辑windows程序

命令简记

cd $GOROOT/src

cp -r $GOROOT /root/go1.4

CGO_ENABLED=0 GOOS=windows GOARCH=amd64 ./make.bash

操作记录

cd $GOROOT/src

测试

package main

import (
    "io/ioutil"
)

func main() {
    content := "看到有很多动物在天上飞，作为一只兔子，我也为此努力了大半生..."

    //如果文件a.txt已经存在那么会忽略权限参数，清空文件内容。文件不存在会创建文件赋予权限
    ioutil.WriteFile("./a.txt",[]byte(content),0777)
}

前面是用root用户设置的，编译时可以用普通用户

hongyun@ubuntu:/export/wks/go/dbm_go/src/test/fil$ CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build ioutil.go 
hongyun@ubuntu:/export/wks/go/dbm_go/src/test/fil$ ll
total 1632
drwxrwxr-x  2 hongyun hongyun    4096 12月  3 14:33 ./
drwxr-xr-x 18 hongyun hongyun    4096 12月  3 14:19 ../
-rwxrwxr-x  1 hongyun hongyun 1656320 12月  3 14:33 ioutil.exe*
-rw-rw-r--  1 hongyun hongyun     341 12月  3 14:29 ioutil.go

将程序放到windows上，执行后会在当前目录下生成一个文件

别名

alias win="CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build "

这样编译windows程序就方便多

hongyun@ubuntu:/export/wks/go/dbm_go/src/test/fil$ win ioutil.go 
hongyun@ubuntu:/export/wks/go/dbm_go/src/test/fil$ ll
