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!
