Hello everybody, There a still many stuff I do not understand how to do with boost::serialization. One of them is the following : Let's say I have the following classes : struct B { int i; template<class Archive> void serialize(Archive & ar, const unsigned int version) { ar & i;} }; struct A { B const *pc; template<class Archive> void serialize(Archive & ar, const unsigned int version) { ar & pc; } }; When I try to serialize a A, I get the following error (MSVC8 beta 2): c:\boost\include\boost-1_33\boost\archive\detail\iserializer.hpp(474) : error C2440: 'reinterpret_cast' : cannot convert from 'const B **__w64 ' to 'void **' Conversion loses qualifiers c:\boost\include\boost-1_33\boost\archive\detail\iserializer.hpp(471) : while compiling class template member function 'void boost::archive::detail::load_pointer_type<Archive,Tptr>::invoke(Archive &,Tptr &)' with [ Archive=boost::archive::text_iarchive, Tptr=const B * ] Of course, if I replace B const *pc by B *pc, then the code works correctly.What can I do to serialize pointers to const data ?
