[Dev-C++] Linker error Undefined Reference

[Peter S. <dy...@ya...>]

Hi,
I am trying to create a sample dll file to be read by
vb. This is just a test to see if I can do it, but if
it succeeds, I will write a true one.
The cpp file is:
#include "Sample.h"
int _stdcall sum(int a, int b)
  {
   int result;
   result = a + b;
   return result;
  }

The h file is: 
int _stdcall sum(int a, int b);

The def file is: 
LIBRARY  Sample.dll
EXPORTS
sum

When I compile I get the linker error:
undefined reference to 'sum'

Is this a bug, or are I doing something wrong?

Thank you,
Peter Stern
