Hi Ferran,
I have never done chroot before, so this was my first attempt. What I did was:
a) Install schroot and debootstrap
b) Creating a chroot at my mounted image
c) Edit the schroot.conf
d) Created basic installation of Ubuntu 14.04 in the chroot
But I encountered errors while trying to create a basic installation of Ubuntu
- all on GLIBC
- Failure trying to run: chroot
/home/llw1n14RTS/gemfi/x86/disks/mountpoint mount -t proc proc /proc
- mount: /lib32/libc.so.6: version 'GLIBC_2.7' not found
(required by mount)
- mount: /lib32/libc.so.6: version 'GLIBC_2.7' not found
(required by /lib/i386-linux-gnu/libblkid.so.1)
- mount: /lib32/libc.so.6: version 'GLIBC_2.7' not found
(required by /lib/i386-linux-gnu/libselinux.so.1)
- mount: /lib32/libc.so.6: version 'GLIBC_2.8' not found
(required by /lib/i386-linux-gnu/libblkid.so.1)
- mount: /lib32/libc.so.6: version 'GLIBC_2.8' not found
(required by /lib/i386-linux-gnu/libmount.so.1)
- mount: /lib32/libc.so.6: version 'GLIBC_2.7' not found
(required by /lib/i386-linux-gnu/libmount.so.1)
I can't create a basic installation of Ubuntu in my mounted image, and I can
chroot to my mounted image. All due to the issue of libc.so.6
A check in the folder /lib32, /lib64 and /lib, I found that libc.so.6 is a link
to libc-2.19.so.
I don't understand what happen. If it is link to libc-2.19.so (which is the
EGLIBC 2.19 I presume), then logically it shouldn’t have any error on GLIBC.
Really needed help here.
Thanks.
Elena

Hi Elena,
Maybe you could try to mount the image you are using to run the experiments in
FS mode, chroot to it and compile these benchmarks there.
You'll also have to mount /proc, /dev and /sys to your mounte image before
chrooting.
Hope this helps,
Ferran O.
