This patch enables building gcc-4.6.4 using gcc-2.95.3 and glibc-2.2.5 * Tweak Makefile to allow overriding NATIVE_SYSTEM_HEADER_DIR using #:makeflags * Add missing limits.h include. * Add SSIZE_MAX define. The SSIZE_MAX define has been added to Mes upstream and can be removed with the next Mes release. * Remove -fbuilding-libgcc flag, it assumes features being present from a newer gcc or glibc. * [MES_BOOTSTRAP_GCC]: Disable threads harder. Upstream status: not presented upstream. diff --git a/gcc/Makefile.in b/gcc/Makefile.in index f3cc49fdb18..bc5718fc9a6 100644 --- a/gcc/Makefile.in +++ b/gcc/Makefile.in @@ -440,7 +440,7 @@ LINKER_PLUGIN_API_H = $(srcdir)/../include/plugin-api.h LTO_SYMTAB_H = $(srcdir)/../include/lto-symtab.h # Default native SYSTEM_HEADER_DIR, to be overridden by targets. -NATIVE_SYSTEM_HEADER_DIR = /usr/include +# NATIVE_SYSTEM_HEADER_DIR = /usr/include # Default cross SYSTEM_HEADER_DIR, to be overridden by targets.

2022-01-05linux-container: Handle CLONE_NEWCGROUP and use it by default....Adds low-level support for launching Linux containers with cgroup namespaces. * gnu/build/linux-container.scm (%namespaces): Add 'cgroup. (namespaces->bit-mask): Handle it. * guix/build/syscalls.scm (CLONE_NEWCGROUP): New variable. Signed-off-by: Ludovic Courtès <ludo@gnu.org> Ryan Sundberg
2020-12-06Revert "linux-container: Correct test for unprivileged user namespace support."...This broke 'guix environment --container' on non-Debian distributions. Fixes <https://bugs.gnu.org/45066>. Reported by luhux <luhux@outlook.com>. This reverts commit 8bc5ca5160db3d82bd5b6b2b7ed80c96f42bd33e. Marius Bakke
2020-12-03linux-container: Correct test for unprivileged user namespace support....Fixes <https://bugs.gnu.org/31977>. Reported by Paul Garlick <pgarlick@tourbillion-technology.com>. * gnu/build/linux-container.scm (unprivileged-user-namespace-supported?): Return #f when the 'userns-file' does not exist. Paul Garlick
2020-10-01linux-container: Reset jailed root permissions....* gnu/build/linux-container.scm (mount-file-systems): Add 'chmod' call. * tests/containers.scm ("call-with-container, mnt namespace, root permissions"): New test. Jelle Licht
2020-09-10build: linux-container: Fix run-container....This is a follow-up of 5316dfc0f125b658e4a2acf7f00f49501663d943. Some users of run-container may expect that the container is jailed, even if there are no mounts. This is the case for some Guix tests. * gnu/build/linux-container.scm (run-container): Do not jail the container when the requested root is "/". Mathieu Othacehe
2020-09-02linux-container: Do not jail the container unconditionally....We may want to run a container inside the MNT namespace, without jailing the container. If RUN-CONTAINER is passed a null MOUNTS list, do not jail the container. * gnu/build/linux-container.scm (run-container): Do not call MOUNT-FILE-SYSTEMS if MOUNTS list is empty. Mathieu Othacehe
