rosdep update</pre>
</div>
<p><tt class="docutils literal"><span class="pre">sudo</span> <span class="pre">rosdep</span> <span class="pre">init</span></tt> will create a <a class="reference external" href="sources_list">sources list</a>

<h2>Updating rosdep<a class="headerlink" href="#updating-rosdep" title="Permalink to this headline">¶</a></h2>
<p>You can update your rosdep database by running:</p>
<div class="highlight-python"><pre>rosdep update</pre>
</div>

<div class="section" id="installating-rosdeps">
<h2>Installating rosdeps<a class="headerlink" href="#installating-rosdeps" title="Permalink to this headline">¶</a></h2>
<p>rosdep takes in the name of a ROS stack or package that you wish to
install the system dependencies for.</p>
<p>Common installation workflow:</p>
<div class="highlight-python"><pre>$ rosdep check ros_comm
All system dependencies have been satisified
$ rosdep install geometry</pre>
</div>
<p>If you’re worried about <tt class="docutils literal"><span class="pre">rosdep</span> <span class="pre">install</span></tt> bringing in system
dependencies you don’t want, you can run <tt class="docutils literal"><span class="pre">rosdep</span> <span class="pre">install</span> <span class="pre">-s</span> <span class="pre"><args></span></tt>
instead to “simulate” the installation. You will be able to see the
commands that rosdep would have run.</p>
<p>Example:</p>
<div class="highlight-python"><pre>$ rosdep install -s ros_comm
#[apt] Installation commands:
sudo apt-get install libapr1-dev
sudo apt-get install libaprutil1-dev
sudo apt-get install libbz2-dev
sudo apt-get install liblog4cxx10-dev
sudo apt-get install pkg-config
sudo apt-get install python-imaging
sudo apt-get install python-numpy
sudo apt-get install python-paramiko
sudo apt-get install python-yaml</pre>
</div>
<p>You can also query rosdep to find out more information about specific
dependencies:</p>
<div class="highlight-python"><pre>$ rosdep keys roscpp
pkg-config
$ rosdep resolve pkg-config
pkg-config
$ rosdep keys geometry
