Dear boost-users, I am trying to use the compression filters with boost.iostreams. I'm following the instructions here http://www.boost.org/doc/libs/1_47_0/libs/iostreams/doc/index.html?path=7 for building, this is my command line (from libs/iostreams/build): "../../../bjam" -sZLIB_SOURCE="C:/Documents and Settings/bradburnd/My Documents/Development/SDK/zlib/1.2.5" I get the following error: ..\..\..\libs\iostreams\src\zlib.cpp(20) : fatal error C1083: Cannot open include file: 'zlib.h': No such file or directory I checked my zlib install location and the zlib.h is at the correct location. Based on what I see in the documentation I don't see why this shouldn't be working. Is there something I'm missing? I am using Windows XP, msvc-9.0 boost 1.45 Best Regards Daniel Bradburn
