Hi,

I have used Eigen::Matrix class in my project. Now i wants to serialize the value of it through Boost::Serialize. Can someone help me on how to achieve that.

My class is following,

class RandomNode {
private:
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive & ar, const unsigned int version)
{
   ar & is_leaf_;
   ar & depth_;
   ar & num_classes_;
   ar & num_features_;
   // Split node members
   ar & random_feature_indices_;
   ar & random_feature_weights_;
   ar & threshold_;
   ar & leftChild_;
   ar & rightChild_;

 }
bool is_leaf_;
int depth_;
int num_classes_;
int num_features_;

// Split node members
VectorXi random_feature_indices_;
VectorXd random_feature_weights_;
double threshold_;
RandomNode* leftChild_;
RandomNode* rightChild_;
 // Methods and so on
}

And i am getting the following error :


/usr/include/boost/serialization/access.hpp:118:9: error: ‘class Eigen::Matrix<double, 10000, 1>’ has no member named ‘serialize’

thanks in advance.

Regards,
Dip
