Package Building

# Daniel Holbach's Packaging Guide
https://wiki.ubuntu.com/PackagingGuide
# Skip introduction go to /GettingStarted

# Install these apps
sudo apt-get install build-essential devscripts debhelper dh-make diff patch gnupg fakeroot \
lintian linda pbuilder

# Create your pbuilder environment (uses it's own sources; config in /etc/pbuilder/pbuilderrc)
sudo pbuilder create --distribution gutsy \
--othermirror "deb http://archive.ubuntu.com/ubuntu gutsy universe multiverse"

# Optional
Add these lines to your ~/.bashrc
export DEBEMAIL="your.email@host.com"
export DEBFULLNAME="First Last"

# Then
source ~/.bashrc

 wget ftp://ftp.gnu.org/gnu/hello/hello-2.2.tar.gz

cp hello-2.2.tar.gz hello_2.2.orig.tar.gz
apt-get source hello

cd ubuntu/hello-2.2/debian

# Now on to actually MAKING a .deb package!

# Make your build environment for hello
mkdir ~/hello-debhelper
cd ~/hello-debhelper

# Grab hello source from upstream
wget http://ftp.gnu.org/gnu/hello/hello-2.2.tar.gz

# Grab Ubuntu-ified version for comparison
mkdir ubuntu
cd ubuntu
apt-get source hello-debhelper
cd ../

# Extract hello
tar zxvf hello-2.2.tar.gz
mv hello-2.2 hello-debhelper-2.2

# Do the Debian! ### STOP HERE!!

#verify your environment variables
echo $DEBFULLNAME
  $your $name
echo $DEBEMAIL	
  yourname@gmail.com

cd hello-debhelper-2.2
dh_make -f ../hello-2.2.tar.gz

cd debian
rm *.ex *.EX

# We'll start by modifying the changelog
vi changelog  # and change the following
1. unstable should become gutsy, or whatever environment you're building for
2. Wipe out everything after Initial release (on that line)
3. Verify your name & <email@address> are correct

# For now we're copying these files, in "reality" you'd modify each one
cp ../../ubuntu/hello-debhelper-2.2/debian/copyright .
cp ../../ubuntu/hello-debhelper-2.2/debian/control .
cp ../../ubuntu/hello-debhelper-2.2/debian/rules .

# Now we create the source package
cd ..
debuild -S -k<your key ID if debuild doesn't find the env variables>

# Build the package with pbuilder
sudo pbuilder build ../*.dsc

# To see your end result
cd /var/cache/pbuilder/result/

# See how broken your .deb actually is!
cd ~/hello-debhelper/
lintian -i *.dsc

# Upgrading an existing package
cd ~/hello-debhelper
wget http://ftp.gnu.org/gnu/hello/hello-2.3.tar.gz
cd hello-debhelper-2.2
uupdate -u hello-2.3.tar.gz
# Cross your fingers, and hope a lot hasn't changed since the previous version

debuild -S
sudo pbuilder build ../*2.3*.dsc   or   ../hello-debhelper_2.3-1.dsc
If everything went well you should have 2.3 debs in /var/cache/pbuilder/result
