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
dchroot: chdir: No such file or directory
dchroot: Child exited non-zero.
dchroot: Operation failed.
What could be wrong?
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

I'm having troubles using IA32 applications under debian-amd64.
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
I decided to follow FAQ with debootstrap'ing. So I run
debootstrap --arch i386 sid /emul/ia32-linux/
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
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
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.
