I want to serialize an existing (low level) class which uses a `std::basic_string<unsigned char>' as member variable. Compiling the code (boost/serialization/string.hpp is included) fails with this message: /usr/include/boost/serialization/access.hpp:109: error: ‘class std::basic_string<unsigned char, std::char_traits<unsigned char>, std::allocator<unsigned char> >’ has no member named ‘serialize’ As I understand, std::string is now treated as a simple data type, but std:basic_string<unsigned char> is not. Is there already existing support for such instanciations of std::basic_string? Any hint on what I can do to get this working?
