[Boost-users] Using regex

I've tried using the regex library in msvc, but keep getting unresolved external errors.. I have; #define BOOST_REGEX_NO_LIB #include using namespace boost; Whenever I do a: regex e(".*test.*"); I keep getting a: 1>test.obj : error LNK2019: unresolved external symbol "private: class boost::basic_regex > & __thiscall boost::basic_regex >::do_assign(char const *,char const *,unsigned int)" (?do_assign@?$basic_regex@DU?$regex_traits@DV?$w32_regex_traits@D@boost@@@boost@@@boost@@AAEAAV12@PBD0I@Z) referenced in function "public: class boost::basic_regex > & __thiscall boost::basic_regex >::assign(char const *,char const *,unsigned int)" (?assign@?$basic_regex@DU?$regex_traits@DV?$w32_regex_traits@D@boost@@@boost@@@boost@@QAEAAV12@PBD0I@Z) Yeah I know it's long, but that's the msvc error ;) Any ideas why it won't work?
