meson and cmake both ask the HOST where libraries go. On Ubuntu the answer is lib/s390x-linux-gnu, so five packages already in the repository ship theirs where Arch's ld.so and pkgconf never look. Measured: expat 12 lz4 6 pacman 6 pkgconf 6 zstd 12 entries Nothing failed. util-linux is where it finally shouted, and even there the rm was the first victim, not the cause. pacman is the one that matters: libalpm.so.16 landed where pacman's own binary cannot load it, and a target installed from that package has no working package manager left to repair itself with. arch-meson now states the libdir devtools has no need to state, and is reinstalled on every run -- editing the copy here changed nothing while /usr/local/bin held a stale one. Four packages call bare meson or cmake and get their own hook. util-linux's old hook chased lib64, which never existed here; it is deleted. --- FR --- meson et cmake demandent tous deux à l'HÔTE où vont les bibliothèques. Sous Ubuntu la réponse est lib/s390x-linux-gnu : cinq paquets déjà dans le dépôt livrent donc les leurs là où ld.so et pkgconf d'Arch ne regarderont jamais. Mesuré : expat 12 lz4 6 pacman 6 pkgconf 6 zstd 12 entrées Rien n'a échoué. util-linux est l'endroit où cela a fini par crier, et même là le rm était la première victime, pas la cause. pacman est celui qui compte : libalpm.so.16 atterrissait là où le binaire de pacman ne peut pas la charger, et une cible installée depuis ce paquet n'a plus de gestionnaire de paquets pour se réparer. arch-meson énonce désormais le libdir que devtools n'a pas besoin d'énoncer, et se réinstalle à chaque exécution : éditer la copie du dépôt ne changeait rien tant que /usr/local/bin en gardait une périmée. Quatre paquets appellent meson ou cmake nu et reçoivent leur crochet. L'ancien crochet util-linux poursuivait un lib64 qui n'a jamais existé ici : il est supprimé. Assisted-by: Claude Opus 5

# lz4: bare `meson setup`, so libdir lands on the Debian multiarch path.
|
|
#
|
|
# This PKGBUILD calls meson directly -- not arch-meson -- so nothing supplies
|
|
# --libdir and meson falls back to default_libdir(), which asks the HOST
|
|
# where libraries go. On this Debian-flavoured builder the answer comes from
|
|
# dpkg-architecture -qDEB_HOST_MULTIARCH, i.e. lib/s390x-linux-gnu. The
|
|
# package built, exited 0, and shipped:
|
|
#
|
|
# usr/lib/s390x-linux-gnu/liblz4.so.1.10.0
|
|
# usr/lib/s390x-linux-gnu/pkgconfig/liblz4.pc
|
|
#
|
|
# Arch's ld.so and pkgconf only read /usr/lib, so on the target every consumer
|
|
# fails to link and `pkg-config liblz4` finds nothing -- while the PKGBUILD
|
|
# still declares provides=('liblz4.so'), a promise the artefact does not keep.
|
|
# The binaries in usr/bin work, which is exactly what makes it look fine.
|
|
#
|
|
# The damage is twofold: liblz4.pc is not merely in the wrong directory, its
|
|
# body also reads libdir=${prefix}/lib/s390x-linux-gnu, so relocating the file
|
|
# would not have been enough. Setting libdir fixes both at once.
|
|
#
|
|
# Anchor on "meson setup", NOT on "meson": build() also runs meson configure
|
|
# and meson compile, package() runs meson install, and check() runs
|
|
# build/meson/programs/lz4 -- a PATH containing the word. There is exactly one
|
|
# setup, asserted below.
|
|
#
|
|
# --libdir survives the later `meson configure`, which only rewrites the
|
|
# options it is handed (-Dcontrib -Dexamples -Dprograms).
