how should i do that, the thing is that i am working in a network linux home and i have to find a way to be make that change in my own proyect not modificating the boost/multiarray.hpp. You will have to excuse my english i am from cuba.

You can do non-instrusive serialization support. Here is what I did for boost::bitset that I keep in a header file in my hobby project. To do something similar for boost/multiarray, you would implement these same three functions with the second parameter changed to match the multiarray, and change the body so that all the relevant bits are saved. namespace boost { namespace serialization { template void save(Archive &ar, const std::bitset<Nb> &bs, const unsigned int version) { unsigned long i(bs.to_ulong()); ar << i; } template void load(Archive &ar, std::bitset<Nb> &bs, const unsigned int version) { unsigned long i; ar >> i; bs = i; } template void serialize(Archive &ar, std::bitset<Nb> &bs, const unsigned int version) { boost::serialization::split_free(ar, bs, version); } } }

i have this code but i don't know how to call it inside a class were i already have a serialize methods for other parameters of the class, i also want to make an xml output file.

#ifndef BOOST_MULTI_ARRAY_S11N_HPP #define BOOST_MULTI_ARRAY_S11N_HPP

//For serialization #include <iomanip> #include <iostream> #include <fstream>

#include #include #include #include

#include //#include

//For multi_array #include

namespace boost { namespace serialization { //----------------------------------------------------------------------------- template< class Archive, class T > void save( Archive & ar, const multi_array& t, const unsigned int /* version */ ) { unsigned int rows = t.shape()[0]; unsigned int cols = t.shape()[1]; ar & rows & cols; for ( unsigned int i=0; i

template< class Archive, class T > void load( Archive & ar, multi_array& t, const unsigned int /* version */ ) { unsigned int rows, cols; ar & rows & cols; t.resize( boost::extents[rows][cols] ); for ( unsigned int i=0; i

template inline void serialize( Archive & ar, multi_array& t, const unsigned int file_version ) { split_free(ar, t, file_version); }

I want to know how can i serialize with boost::serialization a two dimensions boost::multiarray.

You will need to implement serialization support in boost::multiarray
