type map[string]..... is not an expression

[sandi...@gmail.com]

package core

type MyContext struct {

CurClazz          string

CurLine           int

}

--------------------------------------------------------------------------------------------------------------

package main

import (

"fmt"

"pkg/core"

)

var us = map[string]core.MyContext 

--------------------------------------------------------------------------------

I am new to GoLang. Above code is giving build error "type map[string]core.MyContext is not an expression". Can someone please help?

Your map is not initialized, do

either

  var us = make(map[string]core.MyContext)

or

  var us = map[string]core.MyContext{}
