I&#39;m not able to get the wubble simulation working for the ua-ros-pkg at:<br><br><a href="http://code.google.com/p/ua-ros-pkg">http://code.google.com/p/ua-ros-pkg</a><br><br>[Note: I&#39;m a new comer to ROS]<br><br>Summary of Issue:<br>
I am using the Q&amp;A Format provided by the site above. <br><br>a. What steps will reproduce the problem?<br>    1. Follow <a href="http://code.google.com/p/ua-ros-pkg/wiki/DeveloperInstall">http://code.google.com/p/ua-ros-pkg/wiki/DeveloperInstall</a>  to install uav-ros-pkg packages<br>
   2. Run roslaunch wubble_mapping simulation.launch<br><br><br>b. What is the expected output? What do you see instead?<br><br>Expected output: Runs as given in  <a href="http://code.google.com/p/ua-ros-pkg/wiki/ClassInstructions">http://code.google.com/p/ua-ros-pkg/wiki/ClassInstructions</a>.<br>

<br>Latest trunk, on Ubuntu 10.04 /Lucid.<br><br><br>d. Additional Notes?<br><br>world_common isn&#39;t there in the given files, and neither does it get generated during the build. Also, while running make-all.sh I get &#39;Built 46 packages with 1 failure&#39;. My gearbox <br>
has the following issue during the build:<br><br>==========================<br> mkdir -p build/gearbox-svn/build<br>  cd `rospack find gearbox` &amp;&amp; patch -d build/gearbox-svn/src/hokuyo_aist/python --verbose &lt; `rospack find gearbox`/aist_python_mt.patch<br>
  Hmm...  Looks like a unified diff to me...<br>  The text leading up to this was:<br>  --------------------------<br>  |--- CMakeLists.txt    2010-11-05 17:13:52.719057243 -0700<br>  |+++ CMakeLists.txt.ros    2010-11-05 17:12:30.921672551 -0700<br>

  1 out of 1 hunk ignored -- saving rejects to file CMakeLists.txt.rej<br>  done<br>===========================<br><br>I wonder whether this is causing the problem, and am not totally clear as to how to correct this.<br><br>
