Subject: Re: [Boost-users] help needed with bzip2/zlib with boost

Hi,
i had the very same problems yesterday (but i use the gcc compiler).
You have to build the iostream library new:
http://www.boost.org/doc/libs/1_39_0/libs/iostreams/doc/index.html
To do that you have to get to boost/libs/iostream/build in a cmd and
launch bjam with following settings:
bjam "-sNO_COMPRESSION=0" "-sNO_ZLIB=0" "-sZLIB_SOURCE=C:\Dev\zlib"
if you want to use bzip2 just define the variables for bzip2.
Of course you need the files from bzip2 and zlib.
If you have recompiled iostreams you get 2 dlls one for iostreams AND
one for bzip2 or zlib link it with your programm (boost_iostreams AND
bzip2 /zlib).
I hope it helps you,
SK
