Go跨平台交叉编译执行程序

Go作为跨平台的编程语言，与其他跨平台语言相比，它还多了一个跨平台编译的神奇操作

跨平台编译语法

Windows

SET CGO_ENABLED=0
SET GOOS=os
SET GOARCH=arch
go build

CGO_ENABLED这个参数默认为1，开启CGO。 需要指定为0来关闭，因为CGO不支持交叉编译。
GOOS 设置系统类型,可选值: linux ,windows ,darwin ,freebsd
GOARCH 设置底层架构,常用选值: arm64,amd64

Linux&&Mac

export CGO_ENABLED=0 
export GOOS=os 
export GOARCH=arch 
go build

实践

Windows编译

To Linux X86

SET CGO_ENABLED=0
SET GOOS=linux
SET GOARCH=amd64
go build

To Linux Arm64

SET CGO_ENABLED=0
SET GOOS=linux
SET GOARCH=arm64
go build

Linux编译

export CGO_ENABLED=0 
export GOOS=linux
export GOARCH=arm64
go build

效果
