Hi, I built regex as a library using the source (UNICODE char set but not with ICU support). I am able to link to the library in a console program but when I try and link to the library from an MFC project I get a bunch of unresolved errors. Here is one of them: myapp error LNK2019: unresolved external symbol "public: class boost::basic_regex<wchar_t,struct boost::regex_traits<wchar_t,class boost::w32_regex_traits<wchar_t> > > & __thiscall boost::basic_regex<wchar_t,struct boost::regex_traits<wchar_t,class boost::w32_regex_traits<wchar_t> > >::assign(wchar_t const *,wchar_t const *,unsigned int)" (?assign@?$basic_regex@_WU?$regex_traits@_WV?$w32_regex_traits@_W@boost@@@boost@@@boost@@QAEAAV12@PB_W0I@Z) referenced in function "public: class boost::basic_regex<wchar_t,struct boost::regex_traits<wchar_t,class boost::w32_regex_traits<wchar_t> > > & __thiscall boost::basic_regex<wchar_t,struct boost::regex_traits<wchar_t,class boost::w32_regex_traits<wchar_t> >

::assign(wchar_t const *,unsigned int)" (?assign@?$basic_regex@_WU?$regex_traits@_WV?$w32_regex_traits@_W@boost@@@boost@@@boost@@QAEAAV12@PB_WI@Z)

Any help would be greatly appreciated
