Hi, Julio

Thanks for your prompt reply!

Initially, I missed to include <… map.hpp> but after adding the line. It shows somewhat different error message 

/opt/local/include/boost/serialization/access.hpp:118: error: ‘struct std::basic_string<char, std::char_traits<char>, std::allocator<char> >’ has no member named ‘serialize’

and this seems to be related to the member of "const string*".

What I'm doing is adding serialization functionality for someone else's code. This member is from the code. 
Do you think boost serialization isn't supporting such data type?

Thanks again your help!
