This small example program is not working. I have a feeling dmc does not link header files to there cpp files automaticly. If someone could clue me into what settings I need to make this test file work that would be sweet. There are 3 files: main.cpp, mine.h, mine.cpp

CODE::

//  main.cpp
//---------------------------------
#include <cstdlib>
#include <iostream>
#include "mine.h"

using namespace std;

int main(int argc, char *argv[])
{
    int x = foo();
    cout << x << endl;
    system("PAUSE");
    return EXIT_SUCCESS;
}


//mine.h
//------------------------
#ifndef _MINE_H
#define _MINE_H

int foo();

#endif


// mine.cpp
// ------------------
#include "mine.h"

int foo() {
    return 5;
}

I get this error when I try to compile with dmc main.cpp

C:\>dmc main.cpp
link main,,,user32+kernel32/noi;

Compilers does not normally include .cpp files automaically.
I C++ (and C) there is not necessarily any connection between
the name of some .h file and some .cpp file.

You need to list all the .cpp files on the commandline:
dmc main.cpp mine.cpp
