It appears that std::string* is not serializable.
I believe that it is serialzable - but it won't be tracked - which is probably not what you want.
I have need to serialize them, and I'm considering adding the old, unused code in boost/serialization/string.hpp (the stuff #if 0-ed out and marked with "left over from a previous incarnation - strings are now always primitive types") to serialize std::string*'s. I have 2 questions before doing so.
1) What is the rationale for making std::string a primitive, track_never type? After an extensive rereading of the docs, I'm left with only a hazy understanding of what the implications are for primitive vs. non-primitive status.
I used std::string in the archive header. In order to avoid a circular dependency, I made std::string primitive. I wasn't happy about this because it broke the identity between serialization::primitive and the normal usage of the phrase "prmitive type". But it was just too hard to do any other way. Maybe someday that might be looked at again.
2) Can Robert (or anyone else) give me a sense for how likely I am to get myself into trouble doing this? If it matters, I don't need to be able to read old archives containing std::string's.
I would recommend something else: class my_serializable_string : public std::string { .... }; ar << static_cast<my_serialzable_string *>(some_std_string); .... Robert Ramey
