Cross-compilation

Cross-compilation is the process of generating a binary executable file for a different architecture than the one on which you are working.

The main benefit that you receive from cross-compilation is that you do not need a second or third machine to create executable files for different architectures. This means that you basically need just a single machine for your development. Fortunately, Go has built-in support for cross-compilation.

For the purpose of this section, we are going to use the Go code of xCompile.go to illustrate the cross-compilation process. The Go code of xCompile.go is as follows:

package main 
 
import ( 
    "fmt" 
    "runtime" 
) 
 
func main() { 
    fmt.Print("You are using ", runtime.Compiler, " ") 
    fmt.Println("on a", runtime.GOARCH, "machine") 
    fmt.Println(&quot...
