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
