I have a program that runs on RHLE4 and not on OPEN SUSE 10.1. I can not see
why the program doesn't run on SUSE there are no error messages. What I
would like to know is what command I can type in to see what libraries the
program use, so I can compare the libraries between the different operating
systems.

Thanks in advance

Have you tried running it in a terminal?

There are three ways in which a library can be used:

- Statically linked. This would mean the library is part of the
executable, and thus wouldn't pose any problems in your case.

- Dynamically linked, by the compiler. This can be examined with
"ldd /usr/bin/program".

- Dynamically linked, by the program itself. This is done with the
dlopen() function call. If you want to find this, run the
program with "strace /usr/bin/program | grep dlopen".

Good luck on your hunt!

Hi Sybren

Thank you for the quick reply. I did run the program in a terminal, no
errors.

I believe strace logs to stderr, so it would have to be:

strace /usr/bin/program 2>&1 | grep dlopen

It would help if you told us what the program is?

It is nxplotadmin for NX from UGS.
