I have these two source files:

*;return0.asm, compiled with NASM
*;command line: nasm -fcoff return0.asm
*;
*global _return0
*_return0:      xor dx, dx
*                xor eax, eax
*                ret

and

*//ret0.cpp, compiled with GCC and linked to return0.o
*//command line:  gcc ret0.cpp return0.o -lgpp
*//
*//#include<iostream.h>
*//int main()
*{
*        
*
*        int i = extern return0();
*
*        cout<<endl<<endl<<"The number is "<<i<<endl<<endl;
*
*        return 0;
*
*}

The gcc call returns with 
*ret0.cc:undefined reference to 'return0(void)'

So my question is, how do I call a function from a different source file, in
this case, return0()?
