This is already posted in serverfault - and may be more apprpriate there. Reworked a bit from the orginal posting.

We have a product built on CentOS 4 32-bit Linux that runs unmodified on 32- and 64-bit CentOS/RHEL 4 and 5 and SLES 10. It also runs unmodified on SLES 9 64-bit. [SLES 9 32-bit requires a different libstdc++.]

The name of the main binary executable is 'flume'

Yesterday we tried to put this on 64-bit Ubuntu 10 and, even though the file is there and the right size, we get:

-bash: ./flume: No such file or directory

'file flume' shows it to be a 32-bit ELF (can't remember the exact output and the system is on an isolated network)

If put into /usr/local/bin, then 'which flume' returns: /usr/local/bin/flume

The file is marked as executable (did 'chmod +x flume') and lsattr shows no problems with attribute bits.

I was not able to try 'ldd flume' yet. I have also not tried 'strace flume'. Currently I am with an air conditioning failure. [It's been that kind of week!]

I now suspect that some library is not there.

This is a profoundly unhelpful message and one I have never seen before.

Is this peculiar to Ubuntu or perhaps just to this installation.

We gave up and moved to a RHEL 4 system and everything is fine. But I sure would like to know what causes this.
