Regex boost 1.33 - (mingw/w32) linking problem

Hi, I compiled the regex library with: bjam.exe -sTOOLS=mingw -sMINGW_ROOT_DIRECTORY=D:\Dev-Cpp When linking my project with the generated library (libboost_regex-mgw-d-1_33.lib), I get: ../sources/cmdline.o(.text+0x6fe9): In function `_tcf_1': d:/Dev-Cpp/Bin/../lib/gcc/mingw32/3.4.2/../../../../include/c++/3.4.2/bits/basic_string.h:257: undefined reference to `boost::re_detail::cpp_regex_traits_implementation<char>::init()::null_string' ... etc.... Does that mean I should try using STLPort or ? Regards, Arno
