Registering isn't a very long operation, so if registering every time you call works for you, it would be a good solution. I believe the normal registration function would work fine here. The problem arises with the attempt to EXPORT via a unique identifier. Another way would be to use the text string which is part of typeinfo where RTTI is supported. Problem is that that creates archive portability problems. Robert Ramey.

I am not sure of my fact, but can we do it dynamically , as the macro call extended_type_info::self_register() and void extended_type_info::key_register(const char *key_). I ve read in the list some stuff about registering templates like this. template<class> struct pack; template<class T> struct pack<void (T)> { typedef T type; }; BOOST_CLASS_EXPORT( pack<void (DerivedStatus< Algo<int, double > >)>::type ); Can we mix that together to achieve this goal ? In fact, I don't care if we register the type each time we call, I know it s not optimal , but at this point I can live with it. void Add() { B<int>* objectToAdd= new B<int>(0) BoostRegister(B<int>); array.push_back(objectToAdd); } - VDB - "LNK1210: exceeded internal ILK size limit" ------------------------------------------------------------------------------ From: boost-users-bounces@lists.boost.org [mailto:boost-users-bounces@lists.boost.org] On Behalf Of Robert Ramey Sent: 11 mai 2005 02:22 To: boost-users@lists.boost.org Subject: [Boost-users] Re: Serialize templates classes > automatique exportdeclaration I don't know how to avoid this either. If you figure out how to do this let me know Robert Ramey And when i archive the array in another .cpp the exception is raised, because the class B<int> as not been exported. I would like to avoid explicitly declare BOOST_CLASS_EXPORT_GUID(B<int>, "B_int") For each instanciation of B<> somewhere in the glo bal space. ------------------------------------------------------------------------------ _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
