Hi,

I'm trying to deserialize objects from an xml archive containing some gregorian
dates. Using VC7.1 I get the linker error:

serialization.obj : error LNK2019: unresolved external symbol "enum
boost::date_time::special_values __cdecl
boost::gregorian::special_value_from_string(class std::basic_string<char,struct
std::char_traits<char>,class std::allocator<char> > const &)"
(?special_value_from_string_at_gregorian@boost@@YA?AW4special_values_at_date_time_at_2@AB

archive_at_archive@1_at_AAVdate@gregorian_at_1@I_at_Z$0

Any ideas what's causing this?
