Depspec is a small program written in Python that allows you to view a Binaries Dependencies (and symbols that it exports/imports from deps), currently it supports ELF (via marienz'es elf.py) and PE (via. diSlib64). also planned is UT package files (using the parser I wrote) and while it's not really a binary format gentoo ebuilds.

Depspec is highly modeled after Dependency Walker, and was initially made as a linux-compatable alternative to it, however currently it doesn't have all the features and doesn't integrate in windows as well as dependency walker (would like to fill out most of the features, but some things (symbol demangling fex.) are a bit hard).

Requirements

depspec's code has gotten pretty old at this point and it can be tricky to pick up the dependencies on modern systems, I'm planning on either rewriting it in in rust or updading to python 3.x and gobject-introspection fairly soon. you might want to wait for that if you're using a modern OS that doesn't have the older packages listed here, hopefully editing this page is the kick in the pants I need to finish up the port

That said though to currently run depspec you'll need Python 2.5-2.7, tfplib (fetching included in the instructions below), and either:

gtk+ 2.x and pygtk
or, with the multi-frontend branch of depspec there's also a Qt4/PyQt4 frontend if you have Qt4 and PyQt4 installed and you run depspec with depspec -u qt

if you're using windows pywin32 is also needed.

Downloading

you'll need subversion (svn) and breezy (brz) to download tfplib + depspec, after you have them you can run the following commands to checkout tfplib and depspec:


				svn checkout svn://gpio.ca/tfplib/trunk tfplib


				# for the launchpad mirror

				brz branch lp:~tfkyle/depspec/multi-frontend

				# or directly from my server

				brz branch http://bzr.gpio.ca/~kyle/depspec/multi-frontend

Installing

for a premade windows binary see see Packages

if there's no Package or Standalone Binary for your OS/Distro or you want to hack on depspec you'll need to install depspec and tfplib manually.

Both tfplib and depspec use distutils so there's a couple straight-forward ways to install them, you can either:

simply python2 setup.py install in the tfplib and depspec directories (this way each time you make a change you have to run the command again to update the build, the option below can be a better option if you're working on the code and don't want to run the python2 setiup.py install each time you make a change, but otherwise it's a great option.

on unix-like systems the other option is to symlink the module directories directly into the site-packages directory, for example if you have a 32bit python 2.7 install with the site-packages directory in /usr/lib/python2.7/site-packages you could run this from within the tfplib directory:

sudo ln -s $(pwd)/tfplib /usr/lib/python2.7/site-packages/tfplib

And then for depspec you can run the set_active script which does the same thing just automatically by getting the path from python, example output:

$ bash set_active ++ pwd + sudo ln -s /home/kyle/Projects/depspec/multi-frontend/depspec /usr/lib64/python2.7/site-packages/depspec + set +x ++ pwd + sudo ln -s /home/kyle/Projects/depspec/multi-frontend/scripts/depspec /usr/local/bin/depspec + set +x ++ pwd + sudo ln -s /home/kyle/Projects/depspec/multi-frontend/data/depspec.desktop /home/kyle/.local/share/applications/depspec.desktop + set +x
it's a little verbose but it's linking the depspec modules, script and menu item instead of copying them

Packages

There's an older pre-built windows build here, it's fairly old -- from before I added the info tab, but it works for running on older windows systems without having to find a bunch of dependencies.
