executable script gives error "file not found"
Hullo there, I've been setting up a debian box to be a clone of several other like boxen. The new box has amd64 architecture and the old i386. Apart from that they are all still on debian sarge, 2.6 kernels. One thing all the boxen have in common is that they share files over an nfs mount from a server. Some of the files are binary executables. Now, on the new box, they simply won't run: I get the error balloon@capirossi:~$ /home/balloon/bin/balloon-audio-off bash: /home/balloon/bin/balloon-audio-off: No such file or directory The same error appears when running it as root. The file is executable. The selfsame file also runs no problem from the other computers using it. All I know about the file is that it invokes the bash shell and that it is sending data to the parallel port. I put together a test bash script to idiot check bash and that ran ok. I'm baffuffled. Thanks, Jenny

It sounds as if the #! at the beginning of the script is pointing at the wrong location for bash (or at least a wrong location for something). Look at the first line of /home/balloon/bin/balloon-audio-off and see if what it points at exists (and is executable) on the system where it fails to run. -- Chris Green (chris@halon.org.uk)

Thanks, Chris. I can't see inside the file, but I did do a 'which bash' on the new box and on the one on which the script runs, and both return the same: balloon@capirossi:~/bin$ which bash /bin/bash ls -l /bin/bash -rwxr-xr-x 1 root root 729640 2005-05-02 23:39 /bin/bash Is this an adequate test? Thanks, Jenny

Hmmm -- how come you can't see inside the file? Whatever the reason, it would be worth going to some trouble to make it possible to read the file yourself, otherwise you could spend a lot of time shooting in the dark. Good luck again!

That's a possible source of the problem. However, messages like bash: /some/program: No such file or directory can arise whenever something within /some/program fails to find a file or directory it is looking for, and what that "something" is may not be obvious. The only sure way to track down this kind of thing is to work explicitly through the script, and observe which part of it is going wrong! Good luck, Jenny!

What do "file /home/balloon/bin/balloon-audio-off" and "ldd /home/balloon/bin/balloon-audio-off" and "uname -a" say? I suspect your issue is that you're trying to run an i386 binary on an amd64 machine in 64bit mode and that won't work unless you're running it in a chroot AIUI.

Orrrrrrr... apt-get install ia32-libs Should weork for that case, assuming that doesn't use any other libraries. HTH, HAND. -- Brett Parker

Ha ha ha! I just found out that AIUI is an acronym for As I Understand It rather than some weird chroot Artificial Intelligence UI. Still, you'd all be disappointed if I did a post without something idiotic in it :-) Jen
