libxslt reported configure: error: Package requirements (python-3.14) were not met: Package 'python-3.14' not found with python 3.14.7 installed and /usr/lib/pkgconfig/python-3.14.pc present. The chain, none of whose links resembles the others: binutils installs libiberty.a into /usr/lib64, because s390x's default MULTILIB_OSDIRNAME is lib64, creating that path as a REAL directory. meson chooses its default libdir by inspecting the system, and 64-bit plus a real /usr/lib64 means lib64 -- a symlink does not count, which is why Arch never sees this and arch-meson passes no --libdir at all. pkgconf is a meson package, so it installed there and COMPILED IN /usr/lib64/pkgconfig as its search path. Every .pc in the distribution is in /usr/lib/pkgconfig. Fixed at all three levels: binutils pinned to --libdir=/usr/lib, the chroot's arch-meson wrapper pins --libdir lib as a backstop, and the ARTEFACT check -- which said "no Debian multiarch libdir anywhere", truthfully and uselessly -- now also counts paths under usr/lib64. --- FR --- libxslt annonçait configure: error: Package requirements (python-3.14) were not met: Package 'python-3.14' not found avec python 3.14.7 installé et /usr/lib/pkgconfig/python-3.14.pc bien présent. La chaîne, dont aucun maillon ne ressemble aux autres : binutils dépose libiberty.a dans /usr/lib64, le MULTILIB_OSDIRNAME par défaut de s390x, et crée donc ce chemin comme VRAI répertoire. meson choisit son libdir par défaut en inspectant le système : 64 bits plus un vrai /usr/lib64 donne lib64 — un lien ne compte pas, d'où le fait qu'Arch ne voit jamais cela et qu'arch-meson ne passe aucun --libdir. pkgconf étant un paquet meson, il s'y est installé et a COMPILÉ /usr/lib64/pkgconfig comme chemin de recherche. Or tous les .pc de la distribution sont dans /usr/lib/pkgconfig. Corrigé aux trois niveaux : binutils épinglé à --libdir=/usr/lib, l'enveloppe arch-meson du chroot épingle --libdir lib en filet, et le test ARTEFACT — qui répondait « aucun libdir multiarch Debian », véridiquement et inutilement — compte désormais aussi les chemins sous usr/lib64.

# Prove the repository, by installing it and running it.

#
|
|
# WHY THIS IS A SCRIPT AND NOT A PROCEDURE
|
|
#
|
|
# Sixty-eight successful builds said nothing that turned out to be true about
|
|
# whether the port worked. One chroot did -- it found the missing dynamic
|
|
# linker and the missing packages in a single run. That test was then done by
|
|
# hand, so it was not repeatable, and the next question ("is it still true?")
|
|
# had no cheap answer.
|
|
#
|
|
# It has one now. Three things are checked, and they fail for different
|
|
# reasons, so they are reported separately rather than as one verdict:
|
|
#
|
|
# 1. RESOLVE -- pacman's own dependency resolver, with --nodeps OFF. This
|
|
# is the check the bootstrap deliberately skips all the way
|
|
# through stage 1, so it is the first time anything asks
|
|
# whether the repository is internally complete.
|
|
# 2. ARTEFACT -- static audit of every package for host contamination that
|
|
# does not raise an error: Debian multiarch libdirs, files
|
|
# under /usr/local, binaries linked to libselinux.
|
|
# 3. SONAME -- every library any shipped binary ASKS for, minus every
|
|
# library the repository SHIPS. This is the check that reads
|
|
# binaries instead of declarations, and it is the only one
|
|
# that can see an under-declared dependency: kbd's loadkeys
|
|
# needed libxkbcommon.so.0 while kbd declared glibc, gzip
|
|
# and pam. RESOLVE was satisfied, the rootfs installed, and
|
|
# loadkeys could not start.
|
|
# 4. RUN -- chroot in and execute the binaries. The only check that
|
|
# can catch a missing ld.so, because a package whose
|
|
# interpreter is absent installs perfectly.
|
|
#
|
|
# Read-only with respect to repo/s390x. Wipes and rebuilds its own rootfs.
