The Hello World Debian Package

Debian package "hello-world"

In order to package a dummy "hello-world", it's assumed that you have the required software to do it installed and that you follow all the needed steps. It's also assumed that you are running an operating system that allows .deb package installation.

For the impatient, download file hello.tar.gz (contains the necessary files to the "hello-world" package) and go straight ahead to build process section.

Contents of hello.tar.gz: 

• changelog - Contains information about version number, revision, distribution, and urgency. (More info).
• compat - Specifies the compatibility mode. Nowadays, it goes from 1 (default) to 9, each one specifying particular behaviour of some of the tasks execute in particular targets of the build process. (More info).

• copyrights - Contains information about copyrights and licences associated both to the "program" files and package related files (More info).
