Meeting Topic

A talk on the Debian and RPM packaging systems for Linux was given by Stephen Turnbull and Scott Stone. Packaging systems allow easy installation and removal of Linux system software. The packaging systems come with powerful dependencies that inform the user what other programs are needed to ensure a functional Linux system. For example, the installation of the Japanese to English dicitionary xjdic is dependent on edict and kanjidic. An attempt to install xjdic with these packaging systems will result in a search of your system for edict and kanjidic. If the programs are not installed, the packaging system will tell you or install them for you over the Internet or from CD. The packaging systems allow the Linux user to find out information on every program on their system, learn the contents of software packages before installation, and find out what files were installed by what packages. Both rpm and dpkg come with a command line interface and a menu based interface.

How these packaging systems can be used for development of .rpm or .deb packages was also covered.
