i have done in the following way.. even am getting some errors, did i miss any of the headers, or added extra(added extra for sure).

Any suggestions will be accepted

    #include <boost/serialization/utility.hpp>
    #include <boost/serialization/collection_traits.hpp>
    #include <boost/serialization/serialization.hpp>
    #include <boost/serialization/base_object.hpp>
    #include <fstream>
     #include <boost/archive/text_iarchive.hpp>
    #include <boost/archive/text_oarchive.hpp>
    #include <boost/serialization/assume_abstract.hpp>

class fd;

class base: class derived
{
.....
fd *ptr;
.....

friend class boost::serialization::access;
template<class Archive>
void serialize(Archive & ar, const unsigned int file_version)
{
(void) file_version;
ar & ptr;
ar & boost::serialization::base_object<derived>(*this);

}

}; //end of class base

Version::1.36.0
compliler: g++ 4.1.1....

i am getting a error :
error: forward declaration of 'struct fd'
/boost_1_36_0/include/boost-1_36/boost/serialization/access.hpp:109: error: inva
lid use of undefined type 'struct

/project/wipro_virtutech_nobackup/users/niranjan/project_new/boost_1_36_0/include/boost-1_36/boost/serialization/extended_type_info_typeid.hpp:117: note: neither the destructor nor the class-specific operator delete will be called, even if they are declared when the class is defined.

Thanks in advance.....
