Golang go build executable files under different systems

Golang supports the cross-compilation function of generating executable programs for another platform under one platform

 go build, Is a very commonly used command, it can start compilation and compile our package and related dependencies into an executable file

//查看环境变量
go env

 *note*

Two important environment variables GOOS and GOARCH

GOOS refers to the target operating system:

darwin

freebsd

linux

windows

android

dragonfly

netbsd

openbsd

plan9

solaris

GOARCH refers to the architecture of the target processor:

arm

arm64

386

amd64

ppc64

ppc64le

mips64

mips64le

s390x

The effective combination of GOOS and GOARCH supports the generation of multiple executable programs   https://golang.org/doc/install/source#environment

The valid combinations of $GOOS and $GOARCH are:

$GOOS	$GOARCH
aix	ppc64
android	386
android	amd64
android	arm
android	arm64
darwin	amd64
darwin	arm64
dragonfly	amd64
freebsd	386
freebsd	amd64
freebsd	arm
illumos	amd64
js	wasm
linux	386
linux	amd64
linux	arm
linux	arm64
linux	ppc64

Compile 64-bit executable programs for Linux and Windows platforms under Mac:

$ CGO_ENABLED=0  GOOS=linux    GOARCH=amd64 go build main.go
$ CGO_ENABLED=0  GOOS=windows  GOARCH=amd64 go build main.go

Compile 64-bit executable programs for Mac and Windows platforms under Linux:

$ CGO_ENABLED=0  GOOS=darwin   GOARCH=amd64 go build main.go
$ CGO_ENABLED=0  GOOS=windows  GOARCH=amd64 go build main.go

Compile 64-bit executable programs for Mac and Linux platforms under Windows:

$ SET CGO_ENABLED=0  SET GOOS=darwin3 SET GOARCH=amd64 go build main.go
$ SET CGO_ENABLED=0  SET GOOS=linux   SET GOARCH=amd64 go build main.go
