Thanks for all the investigation DM! Just to clarify: From memory, I don't believe the SWORD engine actually uses the copy of zlib which is in svn. It is located at: sword/src/utilfuns/zlib I believe it is included for frontends who wish to use zlib support in the engine, but don't have zlib-devel available for their platform. I would guess BibleCS uses it. I'm quite sure if you enable zlib support (the default) on a linux box it uses your system's zlib-devel package. We could remove it and see if things still compile. :) -Troy. > >On Sep 20, 2007, at 10:02 PM, DM Smith wrote: > >> More results of exploration: >> >> At zlib.net, the home of the zlib code, there is a faq question >> regarding zip archives with a recommended solution: >> >> 11.
