[Boost-users] Installation building errors on win with vc71stlport

Hi, I'm trying to install Boost on windows xp with stlport and Visual Studio .Net 2003. When building it with "bjam "-sTOOLS=vc-7_1-stlport" install" I'm obtaining errors that seems like: vc-C++ bin\boost\libs\date_time\build\boost_date_time.dll\vc-7_1-stlport\debug\threading-multi\greg_month.obj greg_month.cpp C:\Documents and Settings\BOUJAC00\Bureau\boost_1_32_0\boost\lexical_cast.hpp(150) : error C2679: binary '>>' : no operator found which takes a right-hand operand of type 'boost::date_time::date_names_put::string_type' (or there is no acceptable conversion) with [ Config=boost::gregorian::greg_facet_config, charT=wchar_t, OutputIterator=std::ostreambuf_iterator> ] The log of the build is include in log2.txt. Somebody have an idea of what I'm doing wrong? Thanks in advance JA
