string is considered a primitive type and therefore not serializable through a pointer. (shared_ptr<string> contains a pointer to a string. Look in the documentation for serialization of pointers. You can address this by wrapping string in another class just for serialization. Robert Ramey Vjekoslav Brajkovic wrote:
Hi,
I receive a compile time error when I try to serialize shared_ptr<string> in my class. Here are the relevant parts of this class:
/////////1/////////2/////////3/////////4/////////5/////////6/////////7/////////8
#include <boost/serialization/base_object.hpp> #include <boost/serialization/shared_ptr.hpp> #include <boost/serialization/string.hpp>
class chunk_data : public chunk_metadata {
public:
chunk_data(std::string s);
chunk_data( chunk_metadata metadata, boost::shared_ptr<std::string> data_ptr);
chunk_data( boost::filesystem::path path, chunk_metadata::cuid_type chunk_id);
chunk_data( boost::filesystem::path path, chunk_metadata::cuid_type chunk_id, boost::shared_ptr<std::string> data_ptr);
virtual ~chunk_data();
template <typename Archive> void serialize(Archive& ar, const unsigned int version) { boost::serialization::base_object<chunk_metadata>(*this); ar & data_ptr_; }
boost::shared_ptr<std::string> data_ptr_; };
/////////1/////////2/////////3/////////4/////////5/////////6/////////7/////////8
And here are the relevant parts from compilation error.
invalid application of â?~sizeofâ?T to incomplete type â?~boost::STATIC_ASSERTION_FAILURE<false>â?T error: â?~struct std::basic_string<char, std::char_traits<char>, std::allocator<char> >â?T has no member named â?~serializeâ?T
I haven't found any relevant hints about this error neither in the documentation or on the boost mailing list. Also I've attached the compilation log. I would really appreciate any help.
