Try:

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)
    {
            ar & boost::serialization::base_object<derived>(*this);
            ar & ptr;
            ar & ps_core_;
            
    }
}; //end of class base

  hi all,
      
      I am in learning stage of the boost serialization concept. 
      I have one small problem in my project again. Here i have to serialize a pointer of a forward declared class. i dont how to do this. Pls help me to do this. May be the solutuion is too tough, it seems to tough for me, coz i have less knowledge about the c++. 

  I am using,

  Version:1.36.0
  compiler: gnu-gcc-4.1.1-binutils-2.16.1/x86_64-pc-linux2.4/bin/g++

  my code looks like.

  class fd;

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

    
  i have done it like serialization method is

  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 & ps_core_;
              ar & boost::serialization::base_object<derived>(*this);
              
      }
       
  }; //end of class base

  Thanks in advance, Thanks for your time.

  Niranjan
