Re: [Boost-users] [Boost.Serialization] shared_ptr compile-time error.

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 #include #include

class chunk_data : public chunk_metadata {

public:

chunk_data(std::string s);

chunk_data( chunk_metadata metadata, boost::shared_ptrstd::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_ptrstd::string data_ptr);

virtual ~chunk_data();

template <typename Archive> void serialize(Archive& ar, const unsigned int version) { boost::serialization::base_object(*this); ar & data_ptr_; }

boost::shared_ptrstd::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_stringâ?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.
