Re: How to suppress the "multiple definitions of symbol"

[address@hidden]

why dont u try something like this
this is done with all headers

#ifndef __HEADER_IDENTIFIER__
#define __HEADER_IDENTIFIER__

#include <iostream>

// class definitions
//function definitions


#endif

This would automatically take care of duplicacy.
