Su un host AMD64 si possono compilare pacchetti per i386 e amd64.

Installazione e configurazione di Pbuilder
- Installare pbuilder
sudo aptitude install pbuilder debootstrap devscripts cdebootstrap
- Configuralo in modo da supportare più architetture e distribuzioni settando delle variabili:

EOFile
- Creare le tarball per la chroot delle due architetture:
sudo -i
DIST=wheezy ARCH=amd64 pbuilder --create --debootstrap debootstrap --debootstrapopts --keyring=/usr/share/keyrings/debian-archive-keyring.gpg
sudo DIST=lenny ARCH=i386 pbuilder create -debootstrapopts --variant=buildd sudo DIST=lenny ARCH=amd64 pbuilder create -debootstrapopts --variant=buildd
Aggiornamento della tarball image
- Prima di ogni build, è meglio aggiornare la relativa immagine ad esempio con:
sudo DIST=lenny ARCH=i386 pbuilder update
Compilazione di un pacchetto con file .dsc
- Ipotizzando di avere già un pacchetto da compilare con un file .dsc, invece di usare dpkg-buildpackage, usare:
sudo DIST=lenny ARCH=i386 pbuilder build iptables-initd_1.0.0-4.dsc
- I pacchetti risultanti saranno in
/var/cache/pbuilder/lenny-i386/result/
- Se si devono utilizzare delle opzioni da passare dpkg-buildpackage, usarle così:
export DEBFULLNAME="Gabriele Vivinetto" export DEBEMAIL=gabriele.mailing@rvmgroup.it sudo DIST=lenny ARCH=i386 pbuilder build --debbuildopts -kF6D289F6 -tc pigz_2.1.6-1.dsc
Compilazione di un pacchetto per backport
- Prelevare i sorgenti con:
dget http://ftp.de.debian.org/debian/pool/main/a/amanda/amanda_3.2.1-1.1.dsc
- Oppure manualmente dalla pagine del pacchetto source di packages.debian.org
- A questo punto proseguire come al punto precedente
Compilazione di un pacchetto con sorgenti
- Utilizzare pdebuild, che produce i .dsc, e poi proseguire
sudo DIST=squeeze ARCH=amd64 pdebuild sudo DIST=squeeze ARCH=amd64 pbuilder build iptables-initd_1.0.0-5.dsc
