roswtf ERROR Communication with [/foo] raised an error
Hi there!
in the ROS architecture I developed messages are sent and received as expected but when I launch **roswtf** it tells me:
> ERROR Communication with [/foo] raised> an error
for every node in the graph. The last line says:
> ERROR The following nodes should be> connected but aren't:
with a list of every single connection in the graph.
As I said, the system works fine, "**rosnode ping** foo" works fine for every single node and if I send message from the console with **rostopic pub** I don't get any error.
Should I simply skip the errors and move on or is there a reasonable explanation? Thanks.

roswtf and rpath problems in fuerte
I recently noticed that running `roswtf` on every package that I have produces errors related to rpath and the linker. For example, following the tutorial on creating ros packages [here](http://www.ros.org/wiki/ROS/Tutorials/CreatingPackage) you create a new package by running the command
roscreate-pkg beginner_tutorials std_msgs rospy roscpp
Then if I `cd` to the `beginner-tutorials` directory, and run `roswtf`, I get the following error:
Loaded plugin tf.tfwtf
Package: beginner_tutorials
================================================================================
Static checks summary:
Found 1 error(s).
ERROR The following packages have rpath issues in manifest.xml:
* beginner_tutorials: found flag "-L/opt/ros/fuerte/lib", but no matching "-Wl,-rpath,/opt/ros/fuerte/lib"
* std_msgs: found flag "-L/opt/ros/fuerte/lib", but no matching "-Wl,-rpath,/opt/ros/fuerte/lib"
* roscpp: found flag "-L/opt/ros/fuerte/lib", but no matching "-Wl,-rpath,/opt/ros/fuerte/lib"
The question [here](http://answers.ros.org/question/10246/what-is-the-correct-usage-of-rpath-in-manifestxml/) seems to indicate that I should not be using `-L` commands within the export tag. I don't have any references to export or cpp in any of the manifests that produce these errors.
Basically every package I have written produces these same errors. What is causing this? What else should I be including in my manifest.xml?
**EDIT**
Adding the following line to the manifest (per manifest documentation) does not improve anything:

Error in ROSWTF and doubt in ROS_PACKAGE_PATH
My questions are at the end.
When i use the command to find the ROS PACKAGE PATH
sai@sai-desktop:~/fuerte_workspace$ echo $ROS_PACKAGE_PATH

My questions are
1. Initially why did the ROS_PACKAGE_PATH has such a big path?
2. Why are the errors turning up in ROSWTF?
3. The new ROS_PACKAGE_PATH which i have changed is a subset of old PATH. Is it OK to have a big path as the old one or do I have to change to new path?
Please let me know what i should do

ROS Stacks in home and file system
Hi all,
I have a ROS in my home contain RoboEarth and its dependencies and Main ROS [fuerte in Ubuntu 12.04] in file system, I need some stacks from which in my file system so I have to link between all ..
so I use overlay to create my work space and its already in home [fuerte_workspace] how to add RoboEarth and all stacks downloaded with it as once not to add one by one as it does not work

This is what my ROSWTF command returns. This is all of a sudden. We were working with the turtlebot all these days. We were experimenting with lots of new programs that we wrote. Yesterday, the turtlebot did not take goals/initial pose given it from rviz. We didn't understand why and we were confused. We saw similar errors on the internet but none helped us. We use electric.
Also, one of our programs that takes messages from a topic did not respond even after the message was successfully posted to the topic. We checked that by using rostopic echo. For the previous case, we checked that the initial pose and the goals were also reaching the topics, using the same rostopic echo. For both cases, we also checked that the nodes are listening and posting on the related topics.
Please see if you can help. I will provide other details, if necessary.
Note: TurtleBot Tele-operation works very fine.

audio_capture / audio_playback not working
I have been following the ***audio_common*** [tutorial](http://www.ros.org/wiki/audio_common/Tutorials/Streaming%20audio).
I run:
gst-launch-0.10 alsasrc ! audioconvert ! audioresample ! alsasink
and it works correctly.
When I continue the next steps,
roslaunch audio_capture capture.launch
roslaunch audio_play play.launch
no sound is played back.
When I check the topics, **/audio** is there and generating values. **rxgraph** shows them connected. But, when I run **roswtf**, I get:
> ERROR The following nodes should be connected but aren't: > \* /audio_capture->/audio_play (/audio)
I am running on Natty.
Any help is appreciated. Thanks.

groovy roswtf pythonpath errors - python libraries not built?
Hi, I've successfully installed ROS Groovy in Gentoo using the source, and I've completed the beginner tutorials successfully. When it came to the roswtf tutorial, I got all these errors about PYTHONPATH inconsistencies. The output is here: (http://)bpaste.net/show/93407/
It seems to suggest that the python libraries for many packages were not built.
Am I correct in this understanding?
What could I have done while building from source to ensure that the python libraries were built?
Also, about the ROS_PACKAGE_PATH errors - do I need to worry about them?
Looking forward to your help.
Thanks.

ROS Beginner Tutorials: Examining the Simple Service and Client (python) - need some help
Hey guys,
I'm following the **ROS Tutorials** and, using the *Python* language, I'm currently having some issues trying to solve the item **Examining the Simple Service and Client** item ([link text](http: // www.ros .org/wiki/ROS/Tutorials/ExaminingServiceClient)).
When I try to run the **server** (the first step in the tutorial), I get the following message:

And then my Terminal window gets blocked. Before that, when I compiled the code (from the previous tutorial: http :// www.ros .org/wiki/ROS/Tutorials/WritingServiceClient%28python%29) everything seems to work fine:

ROS Beginner Tutorials: Examining the Simple Service and Client (python) - need some help with Client 2
Hey guys,
I'm following the **ROS Tutorials** and, using the *Python* language, I'm currently having some issues trying to solve the item **Examining the Simple Service and Client** item (http ://www.ros .org/wiki/ROS/Tutorials/ExaminingServiceClient). I was already having a problem with the server in this tutorial, but it was solved in another thread (in [link text](http://answers.ros.org/question/70546/ros-beginner-tutorials-examining-the-simple-service-and-client-python-need-some-help/))
My situation is the following:
- I run `roscore` in a terminal
- I run the server (`rosrun beginner_tutorials add_two_ints_server.py`) in another, getting `Ready to add two ints.`
- But when I try to run the client (`rosrun beginner_tutorials add_two_ints_client.py 1 3`), I get the following:
[rospack] Error: stack/package beginner_tutorials not found
Running `roswtf` gives me the following:
viki@ROS:~/catkin_ws/src/beginner_tutorials/scripts$ roswtf
Package: beginner_tutorials
Cannot find dependencies for package [beginner_tutorials]: missing beginner_tutorials

roswtf says rosinstall missing
I started to go through the ROS tutorials and I reached roswtf. Now it says that it cant find the rosinstall python module, but it is installed. Not sure if I ever going to need rosinstall, but right now this warning just bothers me. Is it possible to know why roswtf says there is a problem? Or can I suppress the warning?
I'm running Ubuntu 12.04 with ROS Hydro.

I installed rosinstall_shellcompletion with pip, maybe that caused some nasty stuff under the roof.
