VERSION : 1.9.3

This problem does reproduce with the latest release
.
OS AND HARDWARE : Windows 10 AMD64

I tried building my sum.go file using go build -buildmode=c-shared -o sum.so sum.go.
Instead of it completing, I got this error -buildmode=c-shared not supported on windows/amd64

This is the file:

package main

import "C"
import (
	"fmt"
)

//export add
func add(a, b int) int {
	var sum int = a + b
	fmt.Println("DONE")
	return sum
}

func main() {}

I expected the command to go through and create a sum.so and a sum.h file

Instead I got --> sum.go file using go build -buildmode=c-shared -o sum.so sum.go.

Im doing this so I can import my golang functions into python, is there a way to fix this? Am I using the wrong command, or the wrong file configurations? Thank you.
