[ros-dev] Unable to get wubble launch working with ua-ros-pkg

[GANESH KUMAR]

I'm not able to get the wubble simulation working for the ua-ros-pkg at:

http://code.google.com/p/ua-ros-pkg

[Note: I'm a new comer to ROS]

Summary of Issue:
I am using the Q&A Format provided by the site above.

a. What steps will reproduce the problem?
    1. Follow http://code.google.com/p/ua-ros-pkg/wiki/DeveloperInstall  to
install uav-ros-pkg packages
   2. Run roslaunch wubble_mapping simulation.launch


b. What is the expected output? What do you see instead?

Expected output: Runs as given in
http://code.google.com/p/ua-ros-pkg/wiki/ClassInstructions.

Observed output:
--------------
while processing
/opt/ros/cturtle/stacks/ua-ros-pkg-read-only/arrg/wubble_world/wubble_environments/launch/empty_blocks_world.launch:
while processing
/opt/ros/cturtle/stacks/ua-ros-pkg-read-only/arrg/wubble_world/wubble_environments/launch/world_common.launch:
Invalid roslaunch XML syntax: [Errno 2] No such file or directory:
u'/opt/ros/cturtle/stacks/ua-ros-pkg-read-only/arrg/wubble_world/wubble_environments/launch/world_common.launch'
------------

c. What version of the product are you using? On what operating system?

Latest trunk, on Ubuntu 10.04 /Lucid.


d. Additional Notes?

world_common isn't there in the given files, and neither does it get
generated during the build. Also, while running make-all.sh I get 'Built 46
packages with 1 failure'. My gearbox
has the following issue during the build:

==========================
 mkdir -p build/gearbox-svn/build
  cd `rospack find gearbox` && patch -d
build/gearbox-svn/src/hokuyo_aist/python --verbose < `rospack find
gearbox`/aist_python_mt.patch
  Hmm...  Looks like a unified diff to me...
  The text leading up to this was:
  --------------------------
  |--- CMakeLists.txt    2010-11-05 17:13:52.719057243 -0700
  |+++ CMakeLists.txt.ros    2010-11-05 17:12:30.921672551 -0700
  --------------------------
  Patching file CMakeLists.txt using Plan A...
  Reversed (or previously applied) patch detected!  Assume -R? [n]
  Apply anyway? [n]
  Skipping patch.
  Hunk #1 ignored at 41.
  1 out of 1 hunk ignored -- saving rejects to file CMakeLists.txt.rej
  done
===========================

I wonder whether this is causing the problem, and am not totally clear as to
how to correct this.


Thanks!
