[Boost-users] boost and zlib on win

Hello I've been trying to get boost compiled with zlib on windows. I have win xp, MSVC 2005. Boost is located in c:\cpp libraries\boost Zlib is located in c:\cpp libraries\zlib123 I have tried to build boost iostreams with running bjam from libs\iostreams\build as instructions say.. The command line I used: bjam toolset=msvc "-sZLIB_SOURCE=C:\cpp libraries\zlib123" when I do this it seems like nothing is properly built. The result I get says: ..failed updating 12 targets.. skipped 16 targets... I wonder what am I doing wrong? I want to build boost iostreams so that I can use them with bzip.. Thanks for help Regards
