Utilizzare pbuilder per compilare pacchetti debian di architetture diverse
Su un host AMD64 si possono compilare pacchetti per i386 e amd64.
- Installare pbuilder
sudo aptitude install pbuilder debootstrap devscripts cdebootstrap
- Configuralo in modo da supportare più architetture e distribuzioni settando delle variabili:
cat > ~/pbuilderrc <<'EOFile'

- Creare le tarball per la chroot delle due architetture:
sudo DIST=lenny ARCH=i386 pbuilder create -debootstrapopts --variant=buildd sudo DIST=lenny ARCH=amd64 pbuilder create -debootstrapopts --variant=buildd
- 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
