This is what my debugger says, but I can't find the problem.

You posted the wrong part of the program. The problem is with the two classes you have defined. Just declare the class destructor as virtual and the error will be fixed.

Holding.h:15: warning: `class Holding' has virtual functions but non-virtual destructor
In file included from p6.cpp:12:
Recording.h:13: warning: `class Book::Recording' has virtual functions but non-virtual destructor
p6.cpp:90: error: expected `}' at end of input
Book.h:14: warning: `class Book' has virtual functions but non-virtual destructor

The numbers that I have bolded are line numbers. Unfortunately, the way you posted your code there is no way of knowing which lines they refer to. I suggest you modify your post real quick to make the numbers meaningful.

Once you find the correct lines, the errors should be easy enough to fix, they're pretty elementary.

[edit]
AD covered your other issue. Fix the warnings about non-virtual destructors and the others may correct themselves.

Sorry, I didn't realized that I also cut off the header part. Here's the correct code with a synced error message.

The error is that you haven't defined any default constructors or any destructors. It is not a direct syntax issue, you can't just read through the code and see it.

Like AD said previously, and the warnings you received indicate, you need to properly declare and define/implement your destructors. Make sure you declare them as virtual.

class exBase {
  int anIntMem;
public:
  exBase(): anIntMem(0) {} //default constructor
  virtual ~exBase() {} //virtual destructor
};
class exDerived : public exBase{
  double aDblMem;
public:
  exDerived(): aDblMem(0.0) {} //default constructor
  virtual ~exDerived() {} //virtual destructor
};

Have a look at this for more info.
