Error with go cross-compilation: unsupported GOOS/GOARCH pair linux /amd64

I'm trying to cross-compile go code on windows, targeting linux machine. I have used simple go code to determine target os/platform,

package main

import "fmt"
import "runtime"

func main() {
        fmt.Printf("OS: %s\nArchitecture: %s\n", runtime.GOOS, runtime.GOARCH)
}

Running above code gives me 

OS: linux
Architecture: amd64

hovever when I try to cross compile on windows (using JetBrain's Goland IDE) with

> go version
go version go1.9.2 windows/amd64

using GOOS=linux ;GOARCH=amd64 environment flags, I get following error

cmd/go: unsupported GOOS/GOARCH pair linux /amd64

I am new to golang, so I might be missing something simple, but this error got me stuck. Any help appreciated...

Solution

  • It looks like your GOOS is getting set to "linux " (with an extra space at the end), not "linux".
