everyone. I have a problem with golang 's build.
The details:
I have a folder named "12" and creating a go source file named 12_test.go. Codes are below:
package main
import "fmt"
func main() {
fmt.Println("Hello world")
}
.Then typing "go build 12_test.go". Something going wrong:
"go build command-line-arguments: no buildable Go source files in D:\12"
So,Could someone tell me why? Thanks and apology for my poor English.
