This howto explains how to rebuild yourself software that is packaged in ubuntu. Reasons for rebuilding a package that is already in ubuntu:

• apply a patch
• use a version that doesn't have a .deb
• use different build options, in the uncommon case optional features were disabled.

This is roughly based on BuildingWineFromSource. It is the basic commands needed for the simple cases. Not everything is simple, so it may or may not work for any one package. Once you are fluent with this you may want to contribute your packages, or even package software that never was in ubuntu. For more information about this, see the Masters of the universe site, and the MOTU school there.

Install the build dependencies

The purpose of this step is to install any dependencies necessary to the build process.

sudo apt-get build-dep <package>
sudo apt-get install build-essential fakeroot devscripts

Download the source

mkdir src; cd src
apt-get source <package>
cd <newly created dir> 

At this point, I generally do the "Build Time!" process now to make sure everything is in order. Sometimes the reason you're building from source is because you need to patch the stock release. Now is when you do that.

patch -p1 < SomePackagePatch.patch

For the bold, using the vanilla source isn't hard. If you are lucky, there is a debian dir that has everything you need to just do Build Time! otherwise, I have been able to copy the debian/ dir to the source tree and build from there. (how dangerous is this?) Be sure to update debian/control so that your new package gets a proper version number. This will prevent it from being upgraded to the original ubuntu version. This command will do it semi-automatically:

debchange -i

Change version number in the first line to something like 0.8.3-svn-158, or like <previous-version>.customised.1; then add some comment.

Build time!

dpkg-buildpackage -rfakeroot -us -uc -b

Install the new deb

The build process will create one or more .deb(s) in the parent directory. Install the new package. (package name may be funky - if you got this far you can figure it out.)

sudo debi

Clean up

Once you're satisfied that <package> is working properly, you can now clean up the files used for building, as this frees up quite a bit of disk. Of course, deleting make's working files will mean that if you need to rebuild, make will have to start right from the beginning.

used this for: wine pidgin gocr spe mplayer maintains the debian/ dir as part of it's source, so no need for apt-get source mplayer and shuffling files around, just

 svn co svn://svn.mplayerhq.hu/mplayer/trunk
cd trunk
dpkg-buildpackage -rfakeroot -uc -b

Script that tries to do the whole process, you need to tweak the few things at the top. I left in what works for various packages I have used this on.

# updeb.sh
# updates a deb.  well, makes a deb from current source.

sudo apt-get --assume-yes build-dep $PACKAGE
apt-get source $PACKAGE
# cd into the apt-got dir.

cd $PACKAGE* 
exit
# hide the apt-got source
# mv $SRCDIR $SRCDIR.apt-got
# get working copy
$GETSRCCMD
# bump the version number
# if this is not done, the new deb will be the same version as the current, so won't install. ($0 is the name of this script)
debchange --nmu $0
# build the .deb
dpkg-buildpackage -rfakeroot -uc -b
# install the deb. 
# using this command, on your own :)
echo sudo gdebi $PACKAGE*.deb
