e2fsprogs builds fuse2fs, deletes it, and repackages it. Without fuse3 on the host it was never compiled, so the delete aborted package() after a clean build -- and its sub-package declares fuse3, which this port does not ship, so even a success would have been uninstallable. Three reasons, one direction. libsasl said `libpq-fe.h: No such file or directory` about a file that is there, in /usr/include/postgresql. mysql.h is in /usr/include/mariadb, the same shape one step behind it. Two headers that exist on paths configure does not try is a queue, and this port already wrote down what a queue means: a single missing library is a host dependency, a queue of them is a feature to disable. Arch declares depends=(glibc) for libsasl and says why -- the SQL plugins are dlopened, never linked. python-audit and python-capng go the way python-brotli went, but the reason is stated differently on purpose. Cost was the argument then; measured now, python costs three packages rather than a subtree, so that argument no longer holds. The ABI does: both are cp313 wheels and Arch ships 3.14. --- FR --- e2fsprogs bâtit fuse2fs, le supprime, puis le rempaquette. Sans fuse3 sur l'hôte il n'a jamais été compilé : la suppression interrompait donc package() après une compilation propre — et son sous-paquet déclare fuse3, que ce portage ne livre pas, si bien qu'une réussite aurait été ininstallable. Trois raisons, une seule direction. libsasl annonçait « libpq-fe.h: No such file or directory » à propos d'un fichier présent, sous /usr/include/postgresql. mysql.h est sous /usr/include/mariadb, même forme un cran derrière. Deux en-têtes qui existent sur des chemins que configure n'essaie pas font une file d'attente, et ce dépôt a déjà consigné ce qu'une file signifie : une bibliothèque manquante est une dépendance hôte, une file en est une fonctionnalité à désactiver. Arch déclare depends=(glibc) pour libsasl et explique pourquoi — les greffons SQL sont chargés dynamiquement, jamais liés. python-audit et python-capng suivent python-brotli, mais le motif est énoncé autrement à dessein. C'était le coût alors ; mesuré maintenant, python coûte trois paquets et non un sous-arbre, cet argument ne tient donc plus. L'ABI, si : les deux sont des roues cp313 quand Arch livre la 3.14.

# sql.c:192:10: fatal error: libpq-fe.h: No such file or directory
|
|
#
|
|
# THE TRAP: the header is there.
|
|
#
|
|
# /usr/include/postgresql/libpq-fe.h
|
|
#
|
|
# Debian and Ubuntu put the PostgreSQL client headers in a subdirectory, and
|
|
# the PKGBUILD passes --with-pgsql=/usr/lib, which sends configure looking
|
|
# somewhere else. "No such file or directory" is true of the path it tried and
|
|
# false of the file, so the obvious move -- install libpq-dev -- changes
|
|
# nothing, because it is already installed.
|
|
#
|
|
# AND IT IS A QUEUE, WHICH IS THE REAL POINT. The same PKGBUILD passes
|
|
# --with-mysql=/usr, and mysql.h is at /usr/include/mariadb/mysql.h -- another
|
|
# subdirectory, another header that exists and cannot be found. Fixing the
|
|
# first uncovers the second. This port already wrote the rule down, in
|
|
# install_host_deps, after dbus asked for three documentation tools in a row:
|
|
# a single missing library is a host dependency; a queue of them is a feature
|
|
# that should be disabled.
|
|
#
|
|
# So the SQL auxprop plugin goes, along with the three --with-*sql flags that
|
|
# feed it. What it costs is worth stating precisely, because it is nothing:
|
|
# Arch itself declares depends=(glibc) for this package and says why in a
|
|
# comment at the top of its own PKGBUILD -- "else this would require mariadb
|
|
# and postgresql in [core]". The plugins are dlopened, never linked, so
|
|
# dropping them removes no dependency Arch was tracking and no capability
|
|
# anything in this port uses. libsasl is here because libldap wants SASL
|
|
# authentication; that is the DIGEST/GSSAPI/PLAIN side, all still enabled.
|
|
#
|
|
# Deferred, not architectural: a server that wants SQL auxprop rebuilds this
|
|
# with the include paths supplied. TODO.md records it.
