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 <boost/archive/text_oarchive.hpp>#include <boost/archive/text_iarchive.hpp>and the macroBOOST_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 toinclude 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..
The most recent version of the library has macroBOOST_CLASS_EXPORT_KEY and macroBOOST_CLASS_EXPORT_IMPL to help with this issue. Check the most recent documentation. Robert Ramey
