body: <p>Hello C++ and/or ROS Experts</p>
  
  <p>I just made a fresh install of Ubuntu 12.04 and ROS.</p>
  
  <p>My old installations was also on ubunru 12.04, and it worked great.</p>
  
  <p>But now when i try to make or rosmake on of my project, i get the follwing error:</p>

  <p>Do you have any idear what this mean, or how to fix this?</p>
  
  <p>I installed ROS like this, maybe i need something else?:</p>
  
  <pre><code>sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu precise main" &gt; /etc/apt/sources.list.d/ros-latest.list'
  wget http://packages.ros.org/ros.key -O - | sudo apt-key add -
  sudo apt-get update
  sudo apt-get install ros-fuerte-desktop-full
  echo "source /opt/ros/fuerte/setup.bash" &gt;&gt; ~/.bashrc
  . ~/.bashrc
  sudo apt-get install python-rosinstall python-rosdep
  </code></pre>
