在很多时候，由于开发的方便，会有这样的场景出现，使用Mac开发或使用Windows开发，需要编译成Linux系统的执行文件，那么如何做到？Go语言提供了非常方便的命令行操作，即可实现。

1.Mac下编译Linux, Windows

# Linux
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build filename.go
 
# Windows
CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build filename.go
如: CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build -o helloworld-windows helloworld.go

2.Linux下编译Mac, Windows

# Mac
CGO_ENABLED=0 GOOS=darwin GOARCH=amd64 go build filename.go
 
# Windows
CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build filename.go

3.Windows下编译Mac, Linux

# Mac
SET CGO_ENABLED=0
SET GOOS=darwin
SET GOARCH=amd64
go build filename.go
 
# Linux
SET CGO_ENABLED=0
SET GOOS=linux
SET GOARCH=amd64
go build filename.go

4.参数说明
