How would one go about obtaining all the dependencies for a package?

So to give a little background, I'm trying to pass wireshark(with a custom plugin) through my company's build system.

The build system functions inside a change root thus all the dependencies need to located somewhere inside the chroot. Wireshark has a massive dependency tree that I couldn't possibly import manually one by one.

So my question is, is there a way to conveniently import all the dependency packages somewhere on your local machine. This would mean I would just import the one folder into my change root.

Thanks,
Dave

PS: the build-system's change-root has SMART package manager installed. But the channels it comes with are local ones(very little to choose from). So an alternative solution would be import the repositories that apt-get uses into smart and then use smart to install the packages which is monumentally easier.

Hello and Welcome.
I can tell you for a fact that chasing down dependencies is no fun. Sooner or later you'll run into a circular dependency or dependencies that have, you guessed it, more dependencies! It's called dependency hell.
I think your alternate idea is probably the best way to go.Can you just direct smart to repos that have what you need?

Hmm, that's an interesting method. But how would it be used to list the repositories? Or even just the URI's for all the packages.

From what I saw it only lists the packages that are required minus the ones already on your machine.

As far as I know the repositories for apt-get are in /etc/apt/sources.list. Now I think I can figure out a way to parse the file for the URI's and use smart channel --add but I don't know what to make of some of these url's. for example:
deb [someurl] maverick multiverse
What does the maverick and multiverse stuff mean?

PS: you guys have a feature that doesn't let you post external url's without first making 15 posts. But even if you're quoting someone else's post with external-urls it will register as an attempt by you to do so...

Bump/Edit:

So I went ahead and attempted to add the apt-get repository to smart. I used this command to add the channel:

Code:

smart channel --add mydb type=apt-deb name="DEB database" baseurl=someurl distribution=maverick

And after running this:

Code:

smart update

I get a strange error inside smart's code:

Code:

Loading cache... Updating cache... ###################################################### [100%] Fetching information for 'repo'... Fetching information for 'DEB database'... -> /ubunutu/dists/maverick/Release.gpg Release.gpg ###################################################### [ 50%] -> /ubunutu/dists/maverick/Release Release ###################################################### [ 66%] Traceback (most recent call last): File "/usr/bin/smart", line 195, in ? main(sys.argv[1:]) File "/usr/bin/smart", line 168, in main exitcode = iface.run(opts.command, opts.argv) File "/usr/lib64/python2.4/site-packages/smart/interface.py", line 53, in run result = _command.main(self._ctrl, opts) File "/usr/lib64/python2.4/site-packages/smart/commands/update.py", line 78, in main failed = not ctrl.reloadChannels(channels, caching=NEVER) File "/usr/lib64/python2.4/site-packages/smart/control.py", line 359, in reloadChannels if not channel.fetch(self._fetcher, progress): File "/usr/lib64/python2.4/site-packages/smart/channels/apt_deb.py", line 226, in fetch if item.getStatus() == SUCCEEDED: AttributeError: 'NoneType' object has no attribute 'getStatus'

I have no idea what to make of this =/

PS: i had to remove some urls

If the package is accessible via rpm/yum, you can do this:

Code:

yum deplist package-name

Thanks for trying but I can get the same result from apt-rdepends. What I need is a way to download all the listed packages somewhere onto my machine. Even if it gets a list of urls for the packages, atleast that would be something I can work with.

Sorry, I though I was replying in the Red Hat / Fedora forum! Doh! My bad. Anyway, I think you can use synaptic to do that - just download the files and not install them. I use my SL6/RHEL6 system more than I do my Ubuntu systems, so I am usually thinking more in the terms of yum than aptitude and synaptic... :-)

Is apt installed?

Code:

$ whereis apt-get

Thank you guys for trying to help.

But I ended up writing a script to automatically download the required packages instead. It's worked pretty well.
