Hello,
I am currently trying to serialize the classes of a project I am working on, but I ran into a few compliation errors and I am kind of stuck, so I was hoping somebody here could help me on that.
I am using the 1.43 version of the boost library and gcc 4.4.1. (I'd like to add that all the examples in and tutorials from the documentation work fine for me).
I am trying to serialize a base class called "base" and it's derived class called "de" that use a shared pointer, and afterwards test my implementation by saving the an instance of a "de" object into a text archive and then restoring it.
These is the serialization implementation for my two classes for reference:
---"base.h"-----
#include<iostream>
#include<string>
#include<typeinfo>
#include "../config.h"
#include "../population.h"
#include "../rng.h"
#include
#include
#include
#include
#include
namespace pagmo { namespace algorithm {
/// Base algorithm class.
class base;
/// Alias for shared pointer to base algorithm.
typedef boost::shared_ptr<base> base_ptr;
/// Base algorithm class.
class __PAGMO_VISIBLE base
{
public:
base();
/// Evolve method.
virtual void evolve(population&p) const = 0;
/// Clone method.
virtual base_ptr clone() const = 0;
virtual ~base();
std::string human_readable() const;
virtual std::string get_name() const;
virtual bool is_blocking() const;
protected:
virtual std::string human_readable_extra() const;
protected:
/// Random number generator for double-precision floating point values.
mutable rng_double m_drng;
/// Random number generator for unsigned integer values.
mutable rng_uint32 m_urng;
private:
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive&ar, const unsigned int version){
std::cout<< "Serializing base algorithm"<< version<< std::endl;
}
};
}} //namespaces
std::ostream __PAGMO_VISIBLE_FUNC&operator<<(std::ostream&, const base&);
--------------------
--------"de.h"------
#include<string>
#include "../config.h"
#include "../population.h"
#include "base.h"
#include
namespace pagmo { namespace algorithm {
class __PAGMO_VISIBLE de: public base {
public:
de(int, const double& = 0.8, const double& = 0.9, int = 2);
base_ptr clone() const;
void evolve(population&) const;
std::string get_name() const;
protected:
std::string human_readable_extra() const;
private:
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive&ar, const unsigned int version){
std::cout<< "Serializing de algorithm"<< version<< std::endl;;
ar& boost::serialization::base_object<base>(*this);
ar& m_gen;
ar& m_f;
ar& m_cr;
ar& m_strategy;
}
const int m_gen;
const double m_f;
const double m_cr;
const int m_strategy;
};
}} //namespaces
------------------------------
Saving works fine (and as far as I can tell, based on the documentation examples the information is saved correctly in the text archive). This is the program that I am using to save and restore from archive:
----test_serialzazion.cpp-----
#include<algorithm>
#include
#include
#include<cmath>
#include<numeric>
#include<string>
#include<vector>
#include "../src/pagmo.h"
#include<cstdlib>
#include<iostream>
#include<fstream>
#include
#include
using namespace pagmo;
void save(const algorithm::de&alg, const char* filename) {
std::ofstream ofs( filename );
boost::archive::text_oarchive oa( ofs );
oa<< alg;
}
void restore(algorithm::de& alg, const char* filename)
{
std::ifstream ifs( filename );
boost::archive::text_iarchive ia( ifs );
ia>> alg;
}
int main()
{
algorithm::de de = algorithm::de(500,.8,.8,2);
std::cout<< "Testing algorithm:"<< de<< '\n';
std::string fileName = "test.txt";
save(de, fileName.c_str());
return 0;
}
------------------
However, adding the restore function to restore the object back from the text archive results in the following compilation errors:

Any Ideea of what I am doing wrong or what am I missing? Thank you and sorry for the trouble.
