[Boost-users] [regex] Unresolved external symbols under VC7.1 w/ dynamic linking

Hello, when I define the symbol BOOST_DYN_LINK (in my project settings) I get the following linker errors in MSVC 7.1: FilterDlg.obj : error LNK2001: unresolved external symbol "wchar_t * boost::re_detail::wide_lower_case_map" (?wide_lower_case_map@re_detail@boost@@3PA_WA) FilterDlg.obj : error LNK2001: unresolved external symbol "private: static unsigned short * boost::w32_regex_traits<wchar_t>::wide_unicode_classes" (?wide_unicode_classes@?$w32_regex_traits@_W@boost@@0PAGA) When linking Boost.Regex statically, everything is ok. I am using /Zc:wchar_t ("Treat wchar_t as Built-in type") in my project settings. Any ideas what's going wrong? Regards, Klaus
