Hi all, I am trying to compile Boost on my Windows 2000 box, but I need to enable the zlib support in Boost.Iostreams for the project I'm working on. I read through the "Getting Started" guide and the Boost.Iostreams docs, and I have done what it says to have zlib support installed, but it's not working. I downloaded the zlib DLL from their website and extracted it to C:/zlib Here's my bjam command line: bjam "-sNO_COMPRESSION=0 -sTOOLS=vc-7_1 -sNO_ZLIB=0 -sZLIB_BINARY=zdll -sZLIB_INCLUDE=C:/zlib/include -sZLIB_LIBPATH=C:/zlib/lib" install When I do that, bjam says: "Building Boost.Iostreams with zlib and gzip support disabled. To enable zlib and gzip, consult the Boost.Iostreams documentation." I thought maybe it was a red herring, so I let the compile finish anyway. However, there's no "libboost_zlib-*" in my Boost/lib folder. Can someone enlighten me as to what I've done wrong here? I'm stumped. Thanks, Adam
