zlib stopped on '__builtin_s390_vec_unpackl' requires '-mvx', after its own configure had detected vector support and defined -DHAVE_S390X_VX. Both halves were right, so it was worth measuring rather than patching: host gcc (Ubuntu) --with-arch=z13 --with-tune=z16 default -march=arch11 our gcc nothing default -march=arch5 arch5 is z900, from 2000. Arch's PKGBUILD names no s390x baseline because Arch has no s390x, so ours fell back to the oldest machine imaginable while zlib went on detecting a CPU the compiler had been told to forget. Every distribution picks one of these; this port had never said which, and silence chose 2000. z13 is what Ubuntu s390x already requires, so nothing that runs today stops. Set in two places: makepkg.conf, how this distribution is compiled, and gcc's --with-arch, what the compiler we ship assumes with no flags at all. --- FR --- zlib s'est arrêté sur '__builtin_s390_vec_unpackl' requires '-mvx', après que son propre configure avait détecté le support vectoriel et défini -DHAVE_S390X_VX. Les deux moitiés avaient raison : il fallait mesurer, pas rustiner. gcc de l'hôte --with-arch=z13 --with-tune=z16 défaut -march=arch11 notre gcc rien défaut -march=arch5 arch5, c'est z900, de l'an 2000. Le PKGBUILD d'Arch ne nomme aucune base s390x puisque Arch n'a pas de s390x : le nôtre retombait sur la machine la plus ancienne imaginable pendant que zlib détectait un processeur qu'on avait dit au compilateur d'oublier. Toute distribution en choisit une ; ce portage ne l'avait jamais dit, et le silence a choisi 2000. z13 est ce qu'Ubuntu s390x exige déjà : rien qui tourne aujourd'hui ne cesse de tourner. Posé aux deux endroits : makepkg.conf, comment cette distribution est compilée, et le --with-arch de gcc, ce que suppose le compilateur qu'on livre. Assisted-by: Claude Opus 5
