RE: [Boost-users] building boost on vc7.1 with stlport

I finally compiled the whole thing (by enabling wchar_t builtin support...)
and I ran into the same problem I had before: when I try to USE the regex
class in my code I get the following 2 linker errors:

html to mhtml.obj : error LNK2019: unresolved external symbol "public:
__thiscall boost::reg_expression<char,class boost::regex_traits<char>,class
_STL::allocator<char> >::reg_expression<char,class

*,unsigned int,class _STL::allocator<char> const &)"

Do I have to link manually to something? I thought that's already done in
the headers...
(and I'm still curious as to how one should build boost in vc7.1 with
stlport. Maybe someone should make a faq or something...)
