Hello Michael, thanks for your reply. > You will need to have the —-target switch before the command: > > ./make.sh —-target=aarch64 build > > Don’t forget to fetch the toolchain first and you might need to install a couple of packages that will emulate this architecture. An error message should let you know if anything is missing. I did so, installed some missing packages, ran "/usr/sbin/qemu-binfmt-conf.sh", downloaded the toolchain for aarch64, and tried to start the build. Sadly, it aborts without any (obvious) error message: Packaged toolchain compilation Checking for necessary space on disk [ DONE ] Building LFS stage2 [ FAIL ] Jan 9 13:31:47: Building stage2 ERROR: Building stage2 [ FAIL ] Check /home/pmu/devel/IPFire-development/ipfire-2.x/log/_build.base.log for errors if applicable [ FAIL ] machine:/home/pmu/devel/IPFire-development/ipfire-2.x # cat /home/pmu/devel/IPFire-development/ipfire-2.x/log/_build.base.log Jan 9 13:31:47: Building stage2 That's literally it. Since make.sh does not seem to support a debug/verbose switch, and the output of "bash -x ./make.sh --target=aarch64 build" does not gives any helpful information either, I'm afraid I have to ask for help again. In case it helps: # cat /proc/sys/fs/binfmt_misc/qemu-aarch64 enabled interpreter /usr/bin/qemu-aarch64-binfmt flags: P offset 0 magic 7f454c460201010000000000000000000200b700 mask ffffffffffffff00fffffffffffffffffeffffff Thanks in advance, and best regards, Peter Müller
