Create Ubuntu DEB package from a Qt application

Setting up the environment
sudo apt-get install build-essential devscripts ubuntu-dev-tools debhelper dh-make diff patch gnupg fakeroot lintian pbuilder
sudo apt-get install cdbs


Pbuilder lets you build in a clean, chroot environment, ensuring 
all dependencies are present. Create a file .pbuilderrc

nano .pbuilderrc

and fill it with

COMPONENTS="main restricted universe multiverse"

Then construct the base environment (note: it can take a long time)
sudo pbuilder create


#Export Info Variables
export DEBFULLNAME="VORNAME NACHNAME"
export DEBEMAIL="MAIL@ADRESSE"

#create orig file and debian Folder
dh_make -s -p appname_0.1 -c gpl2 --createorig
#remove crap files
rm debian/*.ex debian/*.EX
rm debian/README.Debian
rm debian/README.source


Then save the debian/rules file with these contents

#!/usr/bin/make -f

include /usr/share/cdbs/1/rules/debhelper.mk
include /usr/share/cdbs/1/class/qmake.mk


#debian/changelog example

Add the following Lines to your .pro-file in the parent directory

TARGET = <application>
target.path = /usr/bin
INSTALLS += target
optional: add supplementary files to the installation

data.path = /usr/share/<application>/data
data.files = data/*
INSTALLS += data

Building the package
alternative version of an existing package (will be uploaded without the .orig.tar.gz file): 
debuild -S -sd

brand new package with no existing version in Ubuntu's repositories (will be uploaded with the .orig.tar.gz file): 
debuild -S -sa
