Le moteur distribué de recherche Yacy sur Raspberry:

• Running YaCy on Raspbian
  • et Debian Java Package
• Oracle JRE for ARM

• ARMv7 Processor rev 5 (v7l)

Je à suivre Installation of YaCy on Debian et hop, après de longue minutes d'installation, ça fonctionne

Après installation, les dossiers et fichiers importants sont:

• l'application:
  • /usr/share/yacy
• Les données:
  • /var/lib/yacy
• Les fichiers de configuration:
  • /etc/yacy/
  • /etc/yacy/yacy.conf is created using the /usr/share/yacy/defaults/yacy.init file on the first run.
• Les logs:
  • /var/log/yacy/

Avec ejdk-8u71-linux-armv6-vfp-hflt.tar.gz

Peut être continuer l'analyse à partir de https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=548729 avec l'outil readelf (package elfutils).

Après quelques minutes (de mise en route ?), ça ne plante suavagement:
