Hi! If you are using VC7 rather VC 7.1 you of course use -sTOOLS=vc-7-stlport instead of -sTOOLS=vc-7_1-stlport. But VC7 is crap. If it is possible I strongly recommend you to upgrade to 7.1 which really works a lot of better than any release before. Also make sure you do a clean rebuild to prevent old compiler switches being stored in the precompiled header files. Boost further requires you to enable the debug mode of stl-port, if I'm not mistakes. Adding the following to stl-user-config.h solved things for me. #ifdef NDEBUG #undef _STLP_DEBUG #else #define _STLP_DEBUG 1 #endif BTW. STLPort 4.6.2 does not work well in conjunction with boost.serialize. A bug in the ostream::write method prevents it from handling writing 0 bytes correctly. Unfortunately the serializer writes 0 bytes in case of empty strings for instance. kind regards Alex

Thanks a lot for your reply! I tried your method and it works! All the compiler errors disappeared. I think the important thing is to turn the feature "stlport-iostreams" on. But the linker still asks me for something like "stlport_vc6.lib". I'm using vc7 now. And I built STLport 4.6.2 also with vc7. But the linker still asks me for something related to vc6. Does any one know the possible causes?
