Struct in library

[szczudlo6]

It is possible to inlude struct in library? When i try to do it then occurs error  "ambiguous call to overloaded function with the same parameters".

See below example.

#property library
#property version   "1.00"
#property strict

#include <clsStruct.mqh>

bool CheckCurrentCandle(int Candle) export
{ 

   strGlobal arr[1]; <- struct in clsStruct file
   int mn = arr[0].magicnumber = 123;
   
   
   if (mn==Candle)
   {    
      return(true);
   }   
   return(false);      
}
