Hi,
 
I built Boost 1.47.0 with ZLIB  and BZIP2 support the same way, i.e. defined the same environment variables.  I also discovered that I could define the same variables on the bjam command line using the “-s” option which I didn’t like because you ended up having to issue a very long bjam command.
 
According to comments in $BOOST_INSTALL_DIR\libs\iostreams\build\Jamfile.v2, the same variables can be setup as ‘path-constant’s in either Boost’s root Jamfile or in user-config.jam which didn’t make sense because the values of some of the variables aren’t paths.  I thus tried using ‘constant’ both in $BOOST_INSTALL_DIR\Jamroot or $BOOST_INSTALL_DIR\user-config.jam and both didn’t seem to work.
 
What is the correct way of setting up these variables other than defining environment variables or adding them to the bjam command line?

Kind regards,
Leo

If something needs to be built into boost, I could probably do that (I don't currently for MPI, but this sounds more generally useful).  However, if this is just a matter of throwing windows binaries for bz2 and zlib in with a bunch of boost libraries, that doesn't seem right.  Is there any documentation on this? I glanced around a bit but didn't see much.

For windows these are built for convenience so that zlib and bz2 are
packaged along with the boost libs since it is not terribly common to
have them available on all windows boxes.  You just have to tell bjam
to build them when building the rest of the code; they are optional
and not built by default.

You are correct but I have never seen bzip2 or zlib included in the boost libraries. I have generally built them separately and then added the following settings to my boost build:
 
set BZIP_PATH=C:\Users\amaclean\wherever\bzip
set ZLIB_PATH=C:\Users\amaclean\wherever\zlib
rem Setting environment for building iostreams with bzip and gzip.
set NO_COMPRESSION=0
set NO_BZIP2=0
set BZIP2_SOURCE="%BZIP_PATH%\bzip2-1.0.6"
set NO_ZLIB=0
set ZLIB_SOURCE="%ZLIB_PATH%\zlib-1.2.5"
 
Maybe they should be included in boost and only used in windows builds.

If you look in the iostreams documentation, in particular the installation section, it talks about widows, bzip2  and zlib.
What I do is to use the latest zlib and bzip sources and put them in a folder and then set the appropriate environment variables as outlined in the iostreams documentation before building.
Of course if you are using dlls then you need to build the zlib dlls as iostreams will need the import library in this case. I just use cmake to do this (for the appropriate compiler).
 
I have attached a windows command file that may be of use to you.
 
Regards
