Hi: I'[m trying to compile boost 1.45, with zlib/bzip2 support in the io streams library. My command line is: bjam toolset=msvc --stagedir=stage/vc/v10/32-bit -sZLIB_SOURCE="c:\progra~1\zlib" -sBZIP2_SOURCE="c:\progra~1\bzip2" --build-type=complete >boost.txt I get the following warning: LINK : fatal error LNK1181: cannot open input file 'boost_zlib.lib' This command line worked for compiling 1.44. Anyone got any ideas? Cheers Sean.
