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
