I'm trying to get F18 running on the globalscale mirabox.
It comes preloaded with Debian Squeeze. As a first step I've tried
downloading the generic
rootfs from the
https://fedoraproject.org/wiki/Architectures/ARM/F18/Remixes page; I've
tried both the arm and armhfp versions, and even tried an armv5 kirkwood
rootfs.
All of them behave the same. I unpack the rootfs into /mnt/f18, and then
try to chroot into
it. The first two or three times I try it, it comes back with either
"Illegal instruction" or
"Segmentation fault", but after a few times I successfully get into the
chroot. Then for pretty
much every command inside it's the same thing. First few times it runs
it fails with one of
the two errors above, then it starts working and appears to keep working
for an indeterminate
amount of time.
I've tried to start rebuilding rpms from source in the chroot but things
never work long enough
to get anything built.
I've also (and this part is probably off-topic) tried building rpms from
the debian environment,
and that's failing because gcc gives an error when explicitly compiling
for armv7:
$ gcc -c ui.c -march=armv7
ui.c:1: error: target CPU does not support ARM mode
Additionally, I've tried building gcc 4.8.0 from source, and that errors
out with:
../.././gcc/config/arm/neon.md: In function 'const char*
output_1551(rtx_def**, rtx)':
../.././gcc/config/arm/neon.md:3953:1: internal compiler error: Illegal
instruction
[(set_attr "neon_type" "neon_shift_2")]
^
../.././gcc/config/arm/neon.md:3953:1: internal compiler error:
Segmentation fault
