[Boost-users] [Serialization]Serialization of pointer to pointers

Hi, all I'm trying to use boost library for serialization of my program which contains many custom class definitions. However, I can't figure out how to handle a class member which is *pointer to pointers* such as 'a' from the following code snippet. class B { A** a; friend class boost::serialization::access; … template<class Archive> void serialize(Archive &ar, const unsigned int version) { ar & a: …. Above code fails to be compiled with the following error message. … /usr/include/boost/archive/detail/oserializer.hpp:148:5: instantiated from ‘void boost::archive::detail::oserializer::save_object_data(boost::archive::detail::basic_oarchive&, const void*) const [with Archive = boost::archive::text_oarchive, T = A*]’ serial0.cpp:118:1: instantiated from here /usr/include/boost/serialization/access.hpp:118:9: error: request for member ‘serialize’ in ‘t’, which is of non-class type ‘A*’ Do we have a typical way to handle a such case? I spend some time to find a solution from the web and tutorials but I couldn't. I'm new to the boost library and your helps will be greatly appreciated. Thanks, Kangkook
