Création d'un environnement de cross compilation complet¶

apt-get update
apt-get install xbuilder xapt haveged
xbuild-chroot-setup precise /opt/chroots/precise-cross
sudo sbuild-update --keygen
sudo sbuild --host=armhf -d precise -c precise-amd64-sbuild

DEB_BUILD_OPTIONS=nocheck
CONFIG_SITE=/etc/dpkg-cross/cross-config.armhf
sudo dpkg --add-architecture armhf

sudo sbuild-shell precise

Et ensuite le configure marche ... jusqu'à planter sur le lancement de lrelease qui est du binaire ARMHF et donc incomprehensible par le cpu local ...
