Hi all: I'm currently trying to compile boost 1.47. I need to use the zlib features in the ioStreams library hence am using the following command line: bjam toolset=msvc --stagedir=stage/vc/v10/32-bit -sZLIB_SOURCE="c:\progra~1\zlib" -sZLIB_LIBPATH="c:\progra~1\zlib\boost_zlib.lib" -sBZIP2_SOURCE="c:\progra~1\bzip2" --build-type=complete >boostv10.txt this fails telling me it carn't open boost_zlib.lib. it appears from the docs that this command line is correct. I'm compiling on windows xp, vc 2010. Also, whilst I think about it, without modifying the default jam file the boost.iostreams library fails to compile, the file gzio.c is no longer in the zlib distribution as of version 1.2.3.9-could this be rectified for future boost releases? Regards Sean.
