If the latter is the answer, then does:
class my_type { friend class ::boost::serialization::access; //... };
need a forward (or full) declaration for "access" before it? Or does that only apply to template functions (or is it just template operators)[1]?
If I understand this correctly, the friend declaration could be restricted to a couple of functions. But compilers are all over the place as to they way they handle this and the above is easy to remember and seems to work well. Of course, you're free to use a more elaborate one for your own classes.

No, you misunderstood. I didn't mean to ask what I should be friendly to, but can I reference "access" without preamble. (I guess you meant that I could restrict friendliness to some member functions of "access".) Could I do: // This is the first line of the file class my_type { friend class ::boost::serialization::access; //... }; or do I need to do: // This is the first line of the file #include <boost/serialization_fwd.hpp> // I'm guessing the name class my_type { friend class ::boost::serialization::access; //... }; or: // This is the first line of the file #include <boost/serialization/access.hpp> // I'm guessing the name class my_type { friend class ::boost::serialization::access; //... }; ? It's actually more of a "rules of C++" question; the section on friends in the standard isn't too clear here. -- Daryle Walker Mac, Internet, and Video Game Junkie darylew AT hotmail DOT com
