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

[Rodayo]

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?

Check this thread.

[Rodayo]

Check.

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:

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

And after running this:

smart update

I get a strange error inside smart's code:

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:

yum deplist package-name

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...

[fanderal]

Is apt installed?

 $ whereis apt-get

[Rodayo]

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.
