Two failures three packages apart, both from the same place: our pacman package ships Arch's configuration verbatim, and Arch's is for x86_64. libxml2/meson.build:1:0: ERROR: Unable to detect linker for compiler `cc ... -march=x86-64 -mtune=generic ...` configure_chroot fixed CARCH, CHOST, MAKEFLAGS and OPTIONS and left CFLAGS alone. They are emptied rather than translated, because that is what stage 1 used -- the host's makepkg.conf has no CFLAGS line at all -- and 179 working packages are the evidence. s390x tuning is a deliberate later choice. Emptied by APPENDING, not commenting. The first attempt put a # in front of each assignment, and CFLAGS spans several lines: commenting the first left the continuations active and the quote unbalanced, so makepkg would not start. Then readline. Its .pc says `Requires.private: termcap` and this repository ships tinfo.pc; nothing provides termcap.pc. Nothing failed at build time -- a .pc is data, and pkg-config only follows Requires.private when a consumer asks. The first consumer to ask was libxml2, in the chroot, one stage and three packages from the cause. --- FR --- Deux échecs à trois paquets d'écart, de la même origine : notre paquet pacman livre la configuration d'Arch telle quelle, et celle d'Arch vise x86_64. libxml2/meson.build:1:0: ERROR: Unable to detect linker for compiler `cc ... -march=x86-64 -mtune=generic ...` configure_chroot corrigeait CARCH, CHOST, MAKEFLAGS et OPTIONS, et laissait CFLAGS. Ils sont vidés plutôt que traduits, car c'est ce qu'a utilisé l'étage 1 — le makepkg.conf de l'hôte n'a aucune ligne CFLAGS — et 179 paquets fonctionnels en sont la preuve. Le réglage pour s390x est un choix ultérieur délibéré. Vidés par AJOUT, non par commentaire. La première tentative mettait un # devant chaque affectation, et CFLAGS s'étend sur plusieurs lignes : commenter la première laissait les continuations actives et le guillemet déséquilibré, si bien que makepkg ne démarrait plus. Puis readline. Son .pc dit « Requires.private: termcap » alors que ce dépôt livre tinfo.pc ; personne ne fournit termcap.pc. Rien n'échouait à la compilation — un .pc est une donnée, et pkg-config ne suit Requires.private que si un consommateur le demande. Le premier à demander fut libxml2, dans le chroot, à une étape et trois paquets de la cause. Assisted-by: Claude Opus 5

# CMake Error at Source/QtDialog/CMakeLists.txt:33 (message):
|
|
# Error when bootstrapping CMake:
|
|
#
|
|
# cmake-gui is a Qt application. Arch lists qt6-base in makedepends and builds
|
|
# it; this port has no Qt and will not grow one to give a bootstrap a dialog
|
|
# box. Same reasoning as pinentry's Qt front end, and the cost is the same
|
|
# thing: a graphical program nothing here can display.
|
|
#
|
|
# WHY cmake IS IN STAGE 1 AT ALL, since it is worth being clear that this is
|
|
# not scope creep: four PKGBUILDs call cmake directly, and stage 2 rebuilds
|
|
# every package inside a chroot that has to contain the build systems. cmake
|
|
# is a tool the REBUILD needs, not a dependency of anything in the repository
|
|
# -- which is why the dependency resolver never asked for it.
|
|
#
|
|
# --sphinx-man and --sphinx-html stay: sphinx-build is installed, and the man
|
|
# pages are worth having.
|
|
#
|
|
# The makedepends entry goes with the flag. Nothing checks it under --nodeps,
|
|
# but a package declaring a build dependency it does not use is the same
|
|
# untruth as gcc-libs declaring libhwasan -- and leaving it would tell the
|
|
# next reader that Qt was needed here.
