As I am not good at c++, I am not sure what you mean by "link the file that
defines this function into the resulting executable". I just include the .h
file that defines the function in the main .cpp file. The compile command I
used is:

g++ sp.cpp (the main cpp file)

I guess there could be some problem here.
