Using C++, how do I correctly inherit from the same base class twice?

Question

This is our ideal inheritance hierarchy:

class Foobar;

class FoobarClient : Foobar;

class FoobarServer : Foobar;

class WindowsFoobar : Foobar;

class UnixF         


        

Answer 1

Have a look at this search. Diamond inheritance is somewhat of contentuous issue and the proper solution dependes on individual situation.

I would like to comment on the Unix/Windows side of things. Generally one would #ifndef things out that are not appropriate for the particular platform. So you would end up with just Foobar compiled for either Windows or Unix using preprocessor directives, not UnixFoobar and WindowsFoobar. See how far you can get using that paradigm before exploring virtual inheritance.
