Hi all,
I'm having trouble with Boost's serialization library that I'm trying to integrate with an existing class hierarchy that used MFC toolkit as the archiver.
It seems that when a serializable class defines a specialized save (or load or serialize for that matter) in addition to the generic method, the serialization library gets confused and ends up not identify properly that the hierarchy of serializable classes uses multiple inheritance and in particular diamond-shaped inheritance.
I've reproduced the problem using the test_diamond code example provided with Boost 1.43 using MS VC 9.0 by adding a save method specialized for archive::text_oarchive to the derived1 class defined in test_diamond.cpp. The following diff shows the implementation of this specialized method:
Without looking at this particular case, I would note that 1.44 - next release contains changes and a new test test_diamond_complex which improves support in this situation. Robert Ramey
