Well, you certainly don't provide enough information for anybody to  
help you here... However, some general remarks:

First: .h files are not "linked", they are "included". Fundamentally  
different concepts.
Second: In which file are Exp::Exp(double) and Exp::execute() defined  
(NOT declared)?

It looks to me as if you're not linking against the file where those  
functions are defined. Now, this can be an object file or a library.  
 From what you describe above I can't tell.
