I've build boost on Windows NT4.0 with following settings: JAM_TOOLSET=VISUALC TOOLS=msvc and until now everything works fine. But when I tried to use boost::regex library I found that I got wrong libraries: I got libboost_regex.lib in four directories: 1) libs\regex\build\bin\libboost_regex.dll\msvc\debug 2) libs\regex\build\bin\libboost_regex.dll\msvc\release 3) libs\regex\build\bin\libboost_regex.lib\msvc\debug\runtime-link- dynamic 4) libs\regex\build\bin\libboost_regex.lib\msvc\debug\runtime-link- dynamic but now when I try to use boost::regex library file regex_library_include.hpp forecs linking against library with name like vc6-re300l.lib. Is there a way to get proper libraries when boost is built or to force compiler to use libboost_regex.lib during linking? Thank you in advance. Best regards Ryszard Niewisiewicz
