[Boost-users] Serialization: multiple definition of 'boost::archive::detail::init_guid...

Hi guys...I've found on google some people with the same problem, but all of them have a partial solution... In practice this error happens where I include a .h file which contain the directive #include #include and the macro BOOST_CLASS_EXPORT() in more than one .cpp file... I have the necessity to serialize/deserialize in more than one .cpp file and at these points I have to include the .h which contains the polymorphic struct that I have to serialize/deserialize. So the partial solution proposed from others to put all the the include in a single file, is not praticable for me.. Do you know another solution?thank you very much... Bye..
