Re: [Boost-users] [Boost.Iostreams] Building iostreams with zlib support

Hi Andreas,

I also got stuck when trying to use zlib in iostreams and found the 
documentation not very helpful. The "Getting started on Microsoft 
Windows" is a bit "unorganized" and outdated. That was mentioned before 
in another thread.

What worked for me was
C:\boost\boost_1_34_1\libs\iostreams\build>bjam
     "-sNO_ZLIB=0"
     "-sZLIB_SOURCE=C:\Libs\zlib123"

You have to think about the threading and linking options (look for the 
specific keywords).
Then some libs with "lib" prefix (for static linking) and without that 
prefix (dynamic linking) should be built as well as the corresponding DLLs.

When you use dynamic linking, make sure to add
BOOST_ALL_DYN_LINK to your defines.

You may also have a look at
http://www.codeproject.com/KB/tips/Building_boost_libraries.aspx
which was helpful for me.

Best regards,
