Four packages -- m4, libtool, groff, libnghttp2 -- failed in prepare() on fatal: unable to access 'https://github.com/...': Could not resolve host Failed to clone 'gl-mod/bootstrap' a second time, aborting Arch takes its sources from git and these fetch gnulib as a submodule, so a chroot with no resolv.conf cannot start the build at all. The retry line is what makepkg prints; the reason sits one line above it. Six more stopped on wget, which links libnettle.so.8 -- Ubuntu's soname, where ours is .9. Our gnutls is already a stage-2 package and correctly wants .9; wget was the last thing holding the old one, and gnulib's bootstrap fetches translation catalogues WITH wget, so the tool it needed to fix itself was itself. It joins libxml2 in STAGE2_HOST_EXTRACT: the host, which has a working wget, runs prepare(); the chroot compiles. Also fixed: my own ca-certificates hook left build() containing nothing but a comment, which bash reports as a syntax error on the closing brace. --- FR --- Quatre paquets — m4, libtool, groff, libnghttp2 — ont échoué dans prepare() sur fatal: unable to access 'https://github.com/...': Could not resolve host Failed to clone 'gl-mod/bootstrap' a second time, aborting Arch tire ses sources de git et ceux-là récupèrent gnulib en sous-module : un chroot sans resolv.conf ne peut pas même commencer. La ligne de reprise est ce qu'affiche makepkg ; la raison est juste au-dessus. Six autres se sont arrêtés sur wget, qui lie libnettle.so.8 — le soname d'Ubuntu, quand le nôtre est .9. Notre gnutls est déjà un paquet d'étage 2 et demande bien .9 ; wget était le dernier à retenir l'ancien, et le bootstrap de gnulib récupère les catalogues de traduction AVEC wget : l'outil dont il avait besoin pour se réparer était lui-même. Il rejoint libxml2 dans STAGE2_HOST_EXTRACT — l'hôte, qui a un wget valide, exécute prepare() ; le chroot compile. Corrigé aussi : mon propre hook ca-certificates laissait build() avec un seul commentaire, ce que bash signale comme une erreur de syntaxe sur l'accolade. Assisted-by: Claude Opus 5 |

Arch Linux s390x
A port of Arch Linux to IBM s390x mainframe architecture with systemd support.
Boots a full Arch Linux system on IBM mainframes (or QEMU s390x emulation) using a hybrid build: cross-compilation for the kernel, native s390x compilation on z/VM for userspace.
Quick Start
make container # build dev container (first time)
cp .env.example .env # configure z/VM access
make all # build kernel + initramfs + systemd
make test-systemd # boot it
What Works
- Arch Linux kernel 6.18.6-arch1 with Arch patches, cross-compiled
- Initramfs via modified mkinitcpio
- Static busybox built natively on z/VM, 2.3MB
- Root filesystem with ext4, switch_root to real rootfs
- Systemd as PID 1
Pacman, bash, and GNU coreutils are not yet ported.
Build System
The build uses two tiers:
Cross-compilation (x86_64 host): Kernel is built in a Fedora 43 container with s390x-linux-gnu-gcc. Initramfs is generated with a patched mkinitcpio that handles cross-architecture binary injection.
Native compilation (s390x z/VM): Busybox and systemd must be built on real s390x hardware. The z/VM system runs RHEL 9.6 with GCC 11.5.0. Scripts handle SSH deployment and retrieval automatically via .env configuration.
