Hello, Simple example: class A { int x; }; class B { int *px; }; There exists a list of B for each A, which points to x. When now serializing B: ar & px; I get an compiletime error, that t is of non classtype 'int'. :: === consoletests, Release === ..\..\code\boost_1_35_0\boost\serialization\serialization.hpp:74: instantiated from `void boost::serialization::serialize(Archive&, T&, unsigned int) [with Archive = boost::archive::text_iarchive, T = int]' ..\..\code\boost_1_35_0\boost\serialization\serialization.hpp:133: instantiated from `void boost::serialization::serialize_adl(Archive&, T&, unsigned int) [with Archive = boost::archive::text_iarchive, T = int]' ..\..\code\boost_1_35_0\boost\archive\detail\iserializer.hpp:152: instantiated from `void boost::archive::detail::iserializer<Archive, T>::load_object_data(boost::archive::detail::basic_iarchive&, void*, unsigned int) const [with Archive = boost::archive::text_iarchive, T = int]' L:\project\consoletests\main.cpp:238: instantiated from here ..\..\code\boost_1_35_0\boost\serialization\access.hpp:109: error: request for member `serialize' in `t', which is of non-class type `int' ..\..\code\boost_1_35_0\boost\serialization\serialization.hpp:74: instantiated from `void boost::serialization::serialize(Archive&, T&, unsigned int) [with Archive = boost::archive::text_oarchive, T = int]' ..\..\code\boost_1_35_0\boost\serialization\serialization.hpp:133: instantiated from `void boost::serialization::serialize_adl(Archive&, T&, unsigned int) [with Archive = boost::archive::text_oarchive, T = int]' ..\..\code\boost_1_35_0\boost\archive\detail\oserializer.hpp:144: instantiated from `void boost::archive::detail::oserializer<Archive, T>::save_object_data(boost::archive::detail::basic_oarchive&, const void*) const [with Archive = boost::archive::text_oarchive, T = int]' L:\project\consoletests\main.cpp:238: instantiated from here ..\..\code\boost_1_35_0\boost\serialization\access.hpp:109: error: request for member `serialize' in `t', which is of non-class type `int' :: === Build finished: 10 errors, 18 warnings === This error does not refer to the class it self, but it only occurs, when serializing int* in my application.

From the docs: "By default, data types designated primitive by Implementation Level class serialization trait are never tracked. If it is desired to track a shared primitive object through a pointer (e.g. a long used as a reference count), It should be wrapped in a class/struct so that it is an identifiable type. The alternative of changing the implementation level of a long would affect all longs serialized in the whole program - probably not what one would intend.

Oh, I see. I just read all the Docs to pointers, and missed Objecttracking. thanks, Jens Weller
