I thought I should probably mention how I'm serializing this container. It is something like this: std::set<std::basic_string<wchar_t> > sMySet; template<class TArchive> void serialize(TArchive & ar, const unsigned int /* file_version */) { ar & boost::serialization::make_nvp("my_set", m_sMySet); } And my archive is an xml archive. Would it be possible that because this is a set of strings and in xml everything has to be name/value pairs the serialization library simply cannot serialize a set of strings because it does not know what name to give in the xml to each element that hold every value of the set? If that is the case how can I serialize this set? Do I have to iterate through it and serialize it myself (provide the names myself)? Once more the linker error is: error LNK2019: unresolved external symbol "void __cdecl boost::serialization::load<class boost::archive::xml_iarchive,class std::list<class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> >,class std::allocator<class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> > > > >(class boost::archive::xml_iarchive &,class std::list<class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> >,class std::allocator<class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> > > > &,unsigned int)" ... referenced in function "public: static void __cdecl boost::serialization::free_loader<class boost::archive::xml_iarchive,class std::list<class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> >,class std::allocator<class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> > > > >::invoke(class boost::archive::xml_iarchive &,class std::list<class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> >,class std::allocator<class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> > > > &,unsigned int)" Thanks -delfin

Yes and yes. I am aware boost::serialization needs to be built. If I were not building it the number of linker errors would be a lot more ;)
Anyway, I built the serialization static libs (no dll seems to be available at this time) and I'm linking against it. However I got the linker error I mentioned before. It seems for some reason I cannot serialize this container (set of wstrings). I also tried changing it to a list of wstrings and got a similar unresolved external. If I try to not serialize the container my program links perfectly.
Sorry my original post was in reply to a completely different one. That was my lazy way to get the email address in the "to" box. I changed the title but I forgot to delete the body of the previous email as I always do.
Anyway, any help you guys can give me? I can try to come up with a small example of my problem if you guys need it.
Thanks

Hello boost,
Hi,
I started using the new serialization library. I use it to serialize a class which contains, among other things, a std::set<std::basic_string<wchar_t> >
The project compiles just fine with many warnings because RTTI is not turned on but it compiles. However it does not link. I get this error:
Are you aware that unlike much of boost, the serialization library contains implementation files that must be built?
Sorry for the length of the error. Anyway, I am using VC++ 7.1. I don't know if it matters but my project has the "Treat wchar_t as built in type" option turned on.
Any idea what am I doing wrong? Thanks,
BTW, you have sent your post as a reply to a post on a completely different subject.
