I am trying to make the very first example in serialization work: http://www.boost.org/libs/serialization/doc/index.html (A Very Simple Case) I get linker errors about missing destructor : boost::archive::detail::basic_pointer_oserializer::~basic_pointer_oserializer(void) And similar errors. It seems the implementation of this destructor, which is declared in: boost/boost/archive/detail/basic_pointer_oserializer.hpp For some reason is implemented in: boost/libs/serialization/src/basic_pointer_oserializer.cpp The first obvious question is offcourse: Why is the implementation not under : boost/boost/archive/src/basic_pointer_oserializer.cpp ? Other questen is why is the "basic_pointer_oserializer.cpp" file not listed anywhere in the jamfiles? I can only find it in the vc71 solution provided in the serialization lib. I am aware that it might work if I use the official jambuilt libraries, but we really want to use our own Cmake files instead of Jam. I suppose I could just add the files like "basic_pointer_oserializer.cpp" to my Cmake files along with others that probably contains implemetations of other linker errors I get. Just its' still strange to me why they are not needed in the original jamfiles. -Martin Lutken
