Simple package building

1. First things first, get puilder:

   apt-get install
   

2. Then build an initial image:

   pbuilder create --distribution sarge --mirror http://ftp.ch.debian.org/debian
   

3. Get package sources (.dsc, .diff.gz and .orig.tar.gz files)

4. Build the package:

   pbuilder build <package>.dsc
   

Complex package building (with dependencies)

While playing with packages, I had the following problem: packageA build a few packages, one of them packageA-dev. The next package I was trying to build package-B had a build dependency on packageA-dev. However, as packageA was not in sarge, pbuilder couldn’t satisfy the dependencies and failed.

Trying to solve this problem, I found the following workaround:

1. Create an apt repository with newly build packages

   dpkg-scanpackages . /dev/null | gzip > Packages.gz    (in /var/cache/pbuilder/result)
   touch Release
   

2. “Mount” the directory to be visible in the chrooted builder environment:

   --bindmounts "/var/cache/pbuilder"  (runtime)
     or
   BINDMOUNTS="/var/cache/puilder"   (config file)
   

3. Add the appropriate apt sources:

   --othermirror "deb file:/var/cache/pbuilder/result ./"  (runtime)
     or
   OTHERMIRROR="deb file:/var/cache/pbuilder/result ./" (config file)
   

BTW: If you’re changing the config file after you’ve build the image, you should update base.tgz file using the following command:

pbuilder update --override-config --distribution sarge

BTW: pbuilder manual can be useful.
