• CowBuilder_+_CCache

CowBuilder is a faster pbuilder build environment, which uses CowDancer, a copy-on-write in userland system (this means it is faster ;). Used together with CCache you get a very fast system for recompiling the same packages over and over aswell.

Well, let's get to the setup. Just follow the steps outlined below:

1. • Install the required packages:
     • • sudo apt-get install cowdancer ccache
2. • Edit ~/.pbuilderrc:
     • • ## Overrides /etc/pbuilderrc # Default distribution DISTRIBUTION=feisty COMPONENTS="main restricted universe multiverse" # Repositories (add the fastest one for you)

         MIRRORSITE=http://archive.ubuntu.com/ubuntu # Bash prompt inside pbuilder export debian_chroot="pbuild$$" # Faster dependency resolution PBUILDERSATISFYDEPENDSCMD="/usr/lib/pbuilder/pbuilder-satisfydepends-gdebi" # CCache setup export CCACHE_DIR="/var/cache/pbuilder/ccache" export PATH="/usr/lib/ccache:${PATH}" EXTRAPACKAGES=ccache BINDMOUNTS="${CCACHE_DIR}"

3. • Create CCache directory (user 1234 is default inside cowbuilder):
     • • sudo mkdir /var/cache/pbuilder/ccache sudo chown 1234 /var/cache/pbuilder/ccache
4. • Create the build environment:
     • sudo cowbuilder --create --distribution feisty

After the (rather long) download and install procedure you can start compiling your own packages like this (example):

• cowbuilder cd flv2mpeg4-0+svn3/ debuild -S -sa cd .. sudo cowbuilder --build flv2mpeg4_0+svn3-1~getdeb1.dsc

The resulting package can be found in /var/cache/pbuilder/result/ . Then you can dput the package to GetDeb like this:

• mkdir -p package/{source,build} mv flv2mpeg4*.* package/source mv /var/cache/pbuilder/result/flv2mpeg4* package/build dput package/source/*.change
