Re: using IA32 chroot: Exec format error
Oh, one more issue related to IA32 chroot'ing. When I run 'dchroot -c ia32 -d openoffice' like suggested in the FAQ, I get $ dchroot -c ia32 -d openoffice (ia32) openoffice dchroot: chdir: No such file or directory dchroot: Child exited non-zero. dchroot: Operation failed. What could be wrong? Thanks, Max Max wrote: Alex, that's it!!! Thank you for your right guess! This needs to be added to FAQ. Now I've got chroot'ing as well as direct running some ia32 binaries to work.

First, I installed ia32-libs with apt-get. I noticed that ia32-libs description/docs do not mention 'chroot' at all but claim that ia32 Linux applications can be executed on 64-bit systems. So I hoped that I would be able just run ia32 binaries as promised. But in reality I got cannot execute binary file errors. Next I tried to get into ia32 enviroment with `chroot /emul/ia32-linux/' command but it didn't work saying that '/bin/bash' is missing. I checked ia32-libs package and indeed it did not provide '/bin/bash'. I decided to follow FAQ with debootstrap'ing. So I run debootstrap --arch i386 sid /emul/ia32-linux/ ftp://ftp.debian.org/debian It did a lot of checking/installing/validating/extracting but finally ended up with the following chroot: cannot run command `mount': Exec format error W: Failure trying to run: chroot /emul/ia32-linux mount -t proc proc /proc umount: /emul/ia32-linux/dev/pts: not found umount: /emul/ia32-linux/dev/shm: not found umount: /emul/ia32-linux/proc/bus/usb: not found umount: /emul/ia32-linux/proc: not mounted So debootstrap installed a lot of IA32 stuff including '/bin/bash' but that stuff still does not work. In particular, chroot'ing now reports # chroot /emul/ia32-linux/ chroot: cannot run command `/bin/bash': Exec format error The same error appears on attempts to run any other application with 'dchroot'. At the same time 'file /emul/ia32-linux/bin/bash' reports /emul/ia32-linux/bin/bash: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.0, dynamically linked (uses shared libs), stripped which looks OK to me. So I got stuck. Please advise. Thanks, Max -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

It looks like a hospital invervention went horribly wrong, and I can only hope the child will recover from this. During surgery, the child for some reason was too excited, the doctor's knife may have slipped, and the operation failed. It's hard to tell exactly what went wrong without more details. Alternatively, it could just be a permissions issue -- the user's home directory must be mounted in /etc/fstab along these lines: /home/ilona /var/chroot/sid-ia32/home/ilona none bind 0 0 Otherwise openoffice can't write to the .openoffice for that user.
