Crosscompile under GoLang

Python is cool and everybody like it, but i also like the Concept of writing some Code, compile it for different Platforms and run it everywhere. Google’s Go Language got the possiblity to compile it for multiple Architectures and Operating Systems at the same time. Why not give a try … ?

Little Hello World

package main

import (
    "fmt"
    "os"
)

func main() {
    s := "world"

    if len(os.Args) > 1 {
        s = os.Args[1]
    }

    fmt.Printf("Hello, %v!", s)
    fmt.Println("")

    if s == "fail" {
        os.Exit(30)
    }
}

go.mod

module example.com/test

go 1.18

Compile and run under macOS

go build

./test
Hello, world!

CrossCompile Script

#!/usr/bin/env bash

archs=(amd64 arm64)
os=(darwin freebsd linux openbsd windows)
name="hello"

for arch in ${archs[@]}; do
  for os in ${os[@]}; do
        env GOOS=${os} GOARCH=${arch} go build -o ${name}_${os}-${arch}
  done
done

Compile it

execute it …
