HOWTO: zlib
Description: Compression library
Click here for ChangeLog
NOTE: I use GNU tar >= 1.13.25 so it's -j for .tar.bz2 files,
it's safe to assume that make, gcc, binutils, fileutils/coreutils, gawk, sed, and grep are prerequisites for almost everything

# Slackware 11.0, 12.0, 12.1, 12.2, 13.0, 13.1: zlib 1.2.3

# I have no idea why you wouldn't want to use the latest, but the other one
# is there if you need it.
# zlib 1.2.5 (latest stable)

# After upgrading the library you should restart anything linked with the
# shared library. If the machine you're upgrading is a non-server or a
# non-critical server, it might be easier to just reboot the machine in
# some cases (lots of things use zlib). To check to see if a binary is
# linked with zlib's shared library, try something like 'ldd /usr/bin/ssh' to
# look for a line of output like this:
# libz.so.1 => /usr/lib/libz.so.1 (0x40138000)
# which shows that /usr/bin/ssh was linked with the zlib shared library.
# You can also try (if you have lsof installed) 'lsof /usr/lib/libz.so'
# which will list currently running applications that have the zlib shared
# library opened.
#
# Rebuild and reinstall anything that was statically linked with zlib.
#
# You can find a partial list of apps that use zlib here:
# http://www.gzip.org/zlib/apps.gz.html
# Remove lines from the elflibs package (elflibs-* in older versions,
# aaa_elflibs-* in Slackware 10.0) that reference libraries that have been
# replaced above:
su

mv -f $FNAME ${FNAME}.`date +%Y%m%d`
