Hi! I had the same problem a few weeks ago. You've got to use the following command line. For debug libs build\bjam.exe -sTOOLS=vc-7_1-stlport "-sBUILD=<define>BOOST_NO_STD_WSTRING" "-sSTLPORT_4.6.2_PATH=D:\Alexander...." "-sstlport-iostreams=on" --with-date_time stage You need to build release libs with an extra step: build\bjam.exe -sTOOLS=vc-7_1-stlport "-sBUILD=release <define>BOOST_NO_STD_WSTRING" "-sSTLPORT_4.6.2_PATH=D:\Alexander...." "-sstlport-iostreams=on" --with-date_time stage This informations is based to 1.32, though. But I think it applies to 1.33 as well. hope this helps Alex

Hi, I tried to build Boost with VC7 and STLport 4.6.2, but failed to compile some source files of Boost.date_time. Error messages are like:

vc-C++ E:\CppLibs\boost_1_33_0\temp\bin\boost\libs\date_time\build\bo ost_date_time.dll\vc7-stlport\release\threading-multi\greg_month.obj greg_month.cpp E:\CppLibs\STLport-4.6.2\stlport\stl\_iterator_base.h(98) : error C2825: ¡°_Iterator::iterator_category¡±£ºcan not form a qualified name

And bjam failed to build DLLs

It seems that auto-linking doesn't function properly. but I can't see why. any idea about these? Thanks in advance!
