Shariing Public Class functions

Hello,  Im new to c++, so....  

I have 2 headerfiles, one class in each, with various public functions (Accesors etc..)  The functions corresponding with each header file are defined in thier own seperate .cpp files.  And there is a main of course.  So thats five files..  

I believe what I am trying to do is aggregation, I want to access a private value from one object to be used in a method from the other object.   So what I assumed would work is calling the public accessor method from the class that I want to retrieve the value from.  But...  I am getting the following compilation error

In function 'void feed()'
'getAttributes" undeclared (first use this function)

I have each seperate header included. so that cant be the problem.  I know the problem is when I try and call that function its not aware of its existance because I am calling it from inside another class..  My question:  Is there any way that I can allow one class to retrieve a private variable from another using the public accessor method from the class where the private value resides?

Many Thanks,
DJ.

(1) Class A has two files:
     classA.h
     classA.cpp

Class B has two files:
    classB.h
    classB.cpp

In Class B you want to access a member function of class A? It looks from the error that you don't use a variable of type B in the function inside class A. That is getAttributes cannot be called without a pointer, reference or object of type B:

    B sometB;
    someB.getAttributes(); // this should be fine.
