    Hi,
    I'm having trouble getting this linker bug to go away.
    I have 2 files: Socket.cpp and Socket.h. I know that these files are legitamite because my professor gave them to me during last semester.

    When I remove socket.cpp, everything compiles just fine. But with Socket.cpp, I get these errors.

    __________________________________________________ _____________

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

    Socket.h includes
    #include <WinSocket.h>
    #include <string>
    #include "ConnectionDLL2.h"


    Socket.cpp includes...
    #include "stdafx.h"
    --> Which includes
    #pragma once
    #include "targetver.h"
    #include <stdio.h>
    #include <windows.h>
    #include <iostream>
    #include <string>
    #include <list>
    #include <map>
    #include <algorithm>
    #include <queue>
    #include <process.h>
    #include <strstream>
    using namespace std;
    #include "Socket.h"


    Also note that I'm using Visual C++ 2008 (which is very similar to VC2005)

    Thanks

    ~Ben S.

    You don't have the necessary libs included for compiling the file socket.cpp
