Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: serialization Group: None Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Robert Ramey (ramey) Summary: polymorphic i/o archives and stl containers problem

Initial Comment: Hello,

i downloaded 1.33.0 RC1 from

http://www.osl.iu.edu/~dgregor/boost-1.33.0/

and tried to recompile some rather large projects with it (currently using 1.32.0). Using MS VC 7.1 and GCC 3.4.4

Doesnt work for boost::serialization:

boost::archive::polymorphic_iarchive& ar boost::archive::polymorphic_oarchive& ar

It bumps on STL containers now:

boost\serialization\collections_load_imp.hpp(118) : error C2039: 'reset_object_address' : is not a member of 'boost::archive::polymorphic_iarchive'

boost\archive\polymorphic_iarchive.hpp(52) : see declaration of 'boost::archive::polymorphic_iarchive'

---- snip "collections_load_imp.hpp" ---- // map input template<class Archive, class Container> struct archive_input_map { inline void operator()(Archive &ar, Container &s) { #if BOOST_WORKAROUND(BOOST_DINKUMWARE_STDLIB, == 1) typedef BOOST_DEDUCED_TYPENAME std::pair< BOOST_DEDUCED_TYPENAME Container::key_type, BOOST_DEDUCED_TYPENAME Container::referent_type > type; #else typedef BOOST_DEDUCED_TYPENAME std::pair< BOOST_DEDUCED_TYPENAME Container::key_type, BOOST_DEDUCED_TYPENAME Container::mapped_type > type; #endif stack_construct<Archive, type> t(ar); // borland fails silently w/o full namespace ar >> boost::serialization::make_nvp("item", t.reference()); std::pair<BOOST_DEDUCED_TYPENAME Container::const_iterator, bool> result = s.insert(t.reference()); assert(result.second); // make sure we inserted a new element ar.reset_object_address(& (* result.first), & t); } }; ---- snip "collections_load_imp.hpp" ----

"ar.reset_object_address(& (* result.first), & t);" is called but not implemeted for these "polymorphic" archive types?

I only found it implemented in "basic_iarchive_impl" (and "basic_oarchive_impl" respective).

What gives? It worked for 1.32 (because there was no "reset_object_address" there).

Is there another (new) way to use polymorphic archive interfaces serializing stl containers?

A. Focht
