Hey Mentors, I've just started making my own deb packages and I'm struggling to get them working properly. You'll have to excuse my lack of technical knowledge, as I've only been programming for a few months. I'm doing this as a learning task with a view to becoming a contributer / maintainer in the future.
To start with, I've made a basic python script that produces a simple GTK based GUI from a text file: <code> #!/usr/bin/python # Code Name: gtk-link-lizard # Created By: Jim Frize, <http://sonodrome.co.uk> # Copyright (C) 2011 Jim Frize, <[email protected]> # Licence: GTK Link Lizard is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.

Add commands to compile the package here touch build-stamp clean: dh_testdir dh_testroot rm -f build-stamp # Add commands to clean up after the build process here dh_clean install: build dh_testdir dh_testroot dh_prep dh_installdirs # Add commands to install the package here mkdir -m 755 -p /usr/share/gtk-link-lizard-1.4 mkdir -m 777 -p ~/Documents/gtk-link-lizard-1.4 install -m 755 $(CURDIR)/gtk-link-lizard.py /usr/share/gtk-link-lizard-1.4 install -m 755 $(CURDIR)/link-lizard-icon.png /usr/share/gtk-link-lizard-1.4 install -m 777 $(CURDIR)/links.txt ~/Documents/gtk-link-lizard-1.4 install -m 755 $(CURDIR)"/GTK Link Lizard.desktop" /usr/share/applications binary-indep: build install #

dh_perl dh_installdeb dh_gencontrol dh_md5sums dh_builddeb binary-arch: build install # Build architecture-dependent files here binary: binary-indep binary-arch .PHONY: build clean binary-indep binary-arch binary install </code> So, I've used this rules file to make a deb package which will install properly on my system, the files all copy/install in the right place and the program functions properly. I do want the package to automatically add the desktop launcher to the gnome menu system, but I'm yet to get that to work. desktop launcher: <code> #!/usr/bin/env xdg-open [Desktop Entry] Version=1.0 Type=Application Terminal=false Exec=/usr/share/gtk-link-lizard-1.4/gtk-link-lizard.py Name=GTK Link Lizard Icon=/usr/share/gtk-link-lizard-1.4/link-lizard-icon.png </code> Another thing I'm not able to do is build a package that removes all it's files on uninstall, it will uninstall from synaptic, but all the files remain. Also from Ubuntu software center the package cannot be uninstalled only reinstalled. The last issue to point out is the fact that the package will not install properly on my other system (Ubuntu 10.04, Linux kernel 2.6.32-28-generic and GNOME 2.30.2), it works fine on my main system which is running Ubuntu 10.10, Linux kernel 2.6.35-25-generic and GNOME 2.32.0. When I try to install it on my other system none of the files copy over and none of the directories are created, the only files that are copied properly are the documents that install a folder and files in the destination path usr/share/doc. Obviously I'm not getting how this is all supposed to work, I've been search and reading for about 3 days now but I'm struggling to find the right info (probably due to my lack of technical knowledge and my unfamiliarity with various terms and nomenclature). I'd appreciate some help demystifying the packaging process, plus I'd like to know of any glaring omissions in my code or any tips tricks that might make my package better.
