Hello,
I want to add serialization support to the Eigen2 matrix class. It
works well (at least at compile time) until I try to serialize a
shared_ptr.
boost::shared_ptr<MatrixXd> shape;
template <typename Archive>
void serialize(Archive& ar, const unsigned int version) {
ar & BOOST_SERIALIZATION_NVP(shape);
};
I receive a long error message that begins with the first error:
/usr/local/include/boost/type_traits/has_new_operator.hpp: In

Has anybody a hint for me what is missing in the matrix class?
second, could anybody please explain to me what
BOOST_SERIALIZATION_SHARED_PTR does and when I have to use it (only
saw it in the demo file).
Thank you,
Best regards
Stefan
