Building binary packages

pbuilder setup

These comments are made on a gentoo distribution and they are based on https://help.ubuntu.com/ubuntu/packagingguide/C/gs-pbuilder.html.

Install fakeroot package

 emerge -av fakeroot

Before running pbuilder, you must fix /etc/hostname temporarily (difference between gentoo and debian environments).

 echo "sirac.geopsy.org" > /etc/hostname

Don't forget to remove that file at the end. You may encounter problems on next startup of you gentoo box. Check that hostname -f works properly. If not, check /etc/host of gentoo tree.

pbuilder does not run out of the box. Apparently, arch is not properly set and it must be forced with --debootstrapopts.

 pbuilder create --debug --distribution hardy --debootstrapopts --arch=amd64 --mirror "ftp://ftp.proxad.net/mirrors/ftp.ubuntu.com/ubuntu" --othermirror "deb http://archive.ubuntu.com/ubuntu hardy universe multiverse" --debootstrapopts --include=gpgv

Every time you touch /etc/apt/sources.list, don't forget to run apt-get update'.

To modify the build environment:

 pbuilder execute --save-after-exec your_script

apt-ftparchive is not installed with emerge, it is in /usr/local/apt and you must set paths before

export LD_LIBRARY_PATH=/usr/local/apt:$LD_LIBRARY_PATH
export PATH=/usr/local/apt:$PATH

cd softwares/packages/ubuntu
apt-ftparchive generate ../apt-ftparchive.conf
apt-ftparchive -c=../apt-release.conf release dists/hardy > dists/hardy/Release
