I am using Windows XP + VC6. My compiler complained about "LINK : fatal error LNK1104: cannot open file "libboost_regex-vc6-mt-sgd-1_32.lib" when using "Debug Multithreaded" run-time library! I alos got a similar error with "Multithreaded" run-time library, but OK with other types of run-time librares.

What is the matter? plase help me. Thank you very much!!

That is one of several regex lib variants that get build when you build Boost, so it should be in your boost-install-path/lib directory. John.
