Hi,
Is it possible to have on an amd64 system, a chrooted or jailed arm64
environment? It's possible to cross-compile an arm6 environment on
amd64 and then chroot into the arm6 environment - is the same possible
for arm64? I can cross-compile arm64 like this:
# SYSROOT=/crossbuild/arm64
# cd /usr/src
# make -j32 TARGET=arm64 TARGET_ARCH=aarch64 buildworld
# make DESTDIR=$SYSROOT TARGET=arm64 TARGET_ARCH=aarch64 installworld
# make DESTDIR=$SYSROOT TARGET=arm TARGET_ARCH=armv6 distribution
# cp /usr/local/bin/qemu-aarch64-static $SYSROOT/sbin
# /usr/sbin/binmiscctl add arm64 --interpreter
"/usr/local/bin/qemu-aarch64" \
--magic
"\x7f\x45\x4c\x46\x02\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\xb7\x00"
\
--mask
"\xff\xff\xff\xff\xff\xff\xff\x00\xff\xff\xff\xff\xff\xff\xff\xff\xfe\xff\xff\xff"
\
--size 20 --set-enabled
# mount -t devfs devfs ${DESTDIR}/dev
then:
# chroot -u root $SYSROOT
then I get the following error:
chroot: /bin/csh: No such file or directory
#
so looked at the chroot, and bin/csh is there!
# ls -lah $SYSROOT/bin |less
total 9144

-r-xr-xr-x 1 root wheel 195K Feb 16 00:43 cp

what am I doing wrong?
