In the meantime, I'm experiencing a much simpler problem. Although I can serialize classes of the form boost::shared_ptr<T>, where T is a class I've defined, I get compilation errors if I try to serialize a boost::shared_ptr<int>.
How can I resolve this?
In such error messages, the first thing to look at is where the actual error happens, indicated by gcc with "instantiated for here". You'll find it's a static assertion and along with it the comment: // The most common cause of trapping here would be serializing // something like shared_ptr<int>. This occurs because int // is never tracked by default. Wrap int in a trackable type As you can then look up in the documentation, for ints the address is not serialised, as their tracking traits default to track_never, which is probably sensible. Simply wrap you int in your own class, then you are fine. And this is as efficient. Jens
