Forum Linux.debian/ubuntu compilation et architecture

bonjour

j'essaie de compiler la source version debian/bookworm 5.2.0-5 de libprelude a partir devuan/chimaera (debian/bullseye)
il y a 9 paquets dont un doc

j'utilise les commandes comme d'habitude:

dpkg-source -x --no-check libprelude_5.2.0-5.dsc
puis
debian/rules binary

cela bloque à la fin:

make[1] : on quitte le répertoire « /home/robertix/libprelude/libprelude-5.2.0 »
   dh_install
   dh_installdocs
   dh_ruby_fixdocs
   dh_installchangelogs
   dh_installman
   dh_python3

il semble qu'il faut spécifier l'architecture demandée
pour ma part amd64 et all

dans la ligne de commande de compilation ou dans le fichier rules ?

fichier /usr/share/dh-python/dhpython/debhelper.py
ligne 214 :
arch = environ['DEB_HOST_ARCH']

voilà le fichier rules:
