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

I'm going to have to make a note in the documentation about this, since it comes up frequently. Compression filters are disabled whenever you set the variable NO_COMPRESSION, *even if you give it the value 0*. In retrospect, I probably should have given the value 0 special treatment; I'm reluctant to change it now, however, since this is one library feature that's hard to test. Please try omitting -sNO_COMPRESSION=0 and see what happens. -- Jonathan Turkanis www.kangaroologic.com
