How to figure out what dependencies a binary uses


What I am trying to do is figure out what deps, well, really what files a binary uses. Like a trace or something. I tried ldd it did not give me what I was looking for. Thanks.

If the binary is running, get is PID using the "ps" command and then use "lsof" to show what files it has open. But I don't know if this is exactly what you're looking for or not.

e.g.,
Code:
ps -ef | grep bash
... say this returns "26312" ... then run:
Code:
lsof -p 26312
You will need to be root to fully trace out some processes if you don't own them.

the best thing to do would be to go to the website of the software developer, try google first and then sourceforge.net and look for the software by name. MOst packages have instructions to install from source, and with that, the needed dependencies.
good luck!

www.rpm-seek.com is a decent site to tell you what depends, supplies, etc. I dont' use rpm distros, but that site has come in handy a few times with dependencies.

Well I can see by the responses that this is an ambiguous question. I thought you were asking what files a running binary uses, and others thought you were asking what files you need to compile a specific binary. I guess you should specify (well actually, answers to both are here already!)

objdump -x /path/to/binary | grep NEEDED maybe what you are looking for...

You guys are awsome. I can peice together what I need by using the two commands below.
Thanks a million guys.

ps aux | grep <whatever> | awk '{print $2}' | xargs -n1 lsof -p > deps.out

objdump -x /path/to/binary | grep
