Hi,
it seems that many tools started to use the core of minizip as part of their
source code. This is quite problematic for distributions since they have to
manually fix those files in case of an (security) bug. Therefore, it seems to
be better to provide a library which can be linked by all programs which need
it.
There are distributions like Gentoo and Fedora which already started to
provide such a library called libminizip [1]. Other distributions like Debian
are currently waiting for actions by upstream before starting to use
libminizip[2]. Gentoo also changed some macros which conflict with other
programs [3] in zconf.h. This made nearly everything fail which included files
from minizip and made it necessary to fix everything by hand.
Some known programs which are known to have minizip included (there are more,
but it is impossible to make a complete list and so I just mention some
prominent ones):
* cegui
* chromium
* gdal
* googleearth (ok, it will not happen that they use the distribution version)
* kicad
* mupen64plus
* R
* psi
* virtuoso
* vlc
Would it be possible to include the patch from Gentoo or a similar one with
the next distribution of zlib?
Thanks
