You must define it to something. In other words, give the function some code! You are using a declaration, which allows the declaring unit to borrow that function from a library at link-time. Chances are the symbol is exported as an undefined symbol (ONLY if that unit references it, though,) as denoted by a "U" when calling nm on the output file. Define it and you will get a "T", which is what I think you want.
