(i.e. precise > instructions) On Debian/Stretch, the dance is as follows: * Install QEMU, especially qemu-user-static, and make sure your kernel supports ARM architecture format (we need /proc/sys/fs/binfmt_misc/qemu-arm) * Setup the chroot environment via 'debootstrap', like in https://elinux.org/Raspbian (s/wheezy/stretch/g) This assumes you are on an ARM host, for cross-running we need some additional steps... * Of course, you cannot just like that run arm binaries on your x86 host, so in the above manual, before chrooting into the Raspbian env, copy /usr/bin/qemu-arm-static (qemu-user-static package) from the host system into usr/bin/ of the chroot environment * Before chrooting, I usually bind-mount /proc, /sys, /dev, /dev/pts from the host into the chroot env * On Debian, you can now chroot into the Raspbian chroot and the binaries therein are run via QEMU and the kernel's foreign architectures support. On host systems like Arch, it might be necessary to do configuration work to get QEMU flying (just heard of it, never tried it) HTH, Christian -- kernel concepts GmbH Christian Hilberg Hauptstrasse 16 firstname.lastname@example.org D-57074 Siegen Tel: +49-271-771091-11 http://www.kernelconcepts.de/ Fax: +49 271-338857-29 HR Siegen, HR B 9613 Geschäftsführer: Ole Reinhardt
