Hi all -
It's possible that I'm still doing something questionable, in which case, I hope you'll let me know. If what I'm doing is okay, perhaps there's a way to disable this warning.
I have a virtual class hierarchy which I use to pass messages via boost.mpi. These messages then perform dispatch through helper objects on either side of the communication. I want to turn off object pointer tracking, so I've set my classes via BOOST_CLASS_TRACKING(myclass, boost::serialization::track_never).
Turning off pointer tracking IS questionable if one is serializing through ponters! why not just leave it on?
If this is expected, how can I turn the warning off? If it is not expected, are there suggestions for what might be changed?
consider the following alternatives a) understand why the warning is there and ignore it on purpose. Include comments in the source code of your app explaining your decision b) enable pointer tracking c) consider different type of polymorphism - e.g. Boost.Variant which is supported by Boost.Serialzation out of the box d) experiment with serialziation via a base class reference. I don't remember of Boost.Serialization has the smarts to stay ahead of the programmer in this case. Robert Ramey
