I concede that this should be added to the documentation. Feel free to open a trac item to remind me of this.

So the solution is to wrap your int inside a class. This will give it a unique type and distinguish from all the other int instances you don't really want to track. Also you can use BOOST_SERIALIZATION to create a wrapper.

Thanks, Robert. Wasn't aware of the BOOST_SERIALIZATION macro. I'll look it up. Another question. It seems that attempts to serialize containers of pointers of any kind throw compiler errors. For example, std::vector<string> str; // compiler is ok with serializing this std::vector pstr; // compiler throws an error The documentation gave me the impression that the serialization lib would dereference the pointers correctly, and perform all the housekeeping around that. Also got the impression that nothing special had to be done for the deserialize step. Is my reading comprehension off? :) Thanks again for your help.
