The sample code:
// main.go in varglobal/
package main
import(
"fmt"
"varglobal/db"
)
var MyGlobalVar string ="Any value :)"
func main(){
db.TryDisplayMyVar()
}
// db.go in varglobal/db/
package db
import "fmt"
func TryDisplayMyVar(){
fmt.Println("Value:",MyGlobalVar)
}
Results of compilation:
# varglobal/db
db/db.go:15:23: undefined: MyGlobalVar
Why can not access global var MyGlobalVar? Any idea?
According Golang docs should be possible. It works when both files are
in the same directory. But when db.go is in another doesn't work.
I tried this sample because I need to update big bunch of code
implementing one global variable from packages. Some good samaritan out
there?
