Hi there, I've been trying to build the regex library but failed miserably. The compiler always dies with an error in "regex_traits.hpp" C:\boost_1_25_0\libs\regex\build>nmake INCLUDES="-I%STL_INCLUDE%" -fvc6-stlport.mak Microsoft (R) Program Maintenance Utility Version 6.00.8168.0 Copyright (C) Microsoft Corp 1988-1998.

The error stays the same if I try the new build system with the following command line: jam -ftools/build/allyourbase.jam -sTOOLS="msvc" -sBUILD="<include>%STL_INCLUDE%" If I look at the offending line in "regex_traits.hpp" it reads const std::ctype<char>* pctype; Obviously it doesn't know that ctype lives in the std namespace. It works if I use the STL supplied by Microsoft. Does anyone else use this combination of compiler and library and managed to successfully build the regex library? Markus
