Can you specify what exactly you want to publish? Or add some piece of code to understand the need.

@gvdhoorn: Actually, I have faced somewhat same problem that I fixed with the same as I mentioned above. If you think it

Hi @hakimROS, can you provide the link of the tutorial that you are going through?? And mention the points as well that

if you advertise a topic like node.advertise<camerainfo>("camera_info", 1); , so in CameraInfo class, there is more than one data types are available like uint32, string etc.

Hi, you can publish even more than two data types but it depends on what you want to send.

Ok, thanks. I will try without changing manually the path of ros.

Ok, thanks. I will try to do it without manually changing the path.

Sorry,I think my earlier comment is not clear enough. So clearing it. ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:~/<path_to_work_space_of_ros>

and then $ source ~/.bashrc

But it worked for me.

Hi, add the following lines to the .bashrc file as well as update the current bash shell with it so that we don't get any build errors.

#Update ROS path to ROS environment export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:~/ROS_WS $ source ~/.bashrc

just replace ROS_WS with your ros work space directory.

Hi nansmallgong, can just show me your launch file?

Hi ryanhowarth, just add required="true" in your tag.

Hi g.bardaro, check the 2nd answer on http://answers.ros.org/question/25018... It worked for me.

Hi Ma8sa,

DSO missing is a run time error. So just check your make file where you are linking the library from. And correct it.

So I followed one step that I have mentioned in my answer and now it is working properly and shutting down too.

Hi rbbg,

Thanks for responding. Actually I tried with the above step that you shared, but when I was calling ros::shutdown(), the node was being stopped but roslaunch was existing. Hence I was not able to come out of the program.

I found the solution. I added the required="true" option to one of the <node> tags in my launch file. e.g. <node ns="stereo" pkg="uvc_camera" type="tara_node" name="uvc_camera" output="screen" required="true">

Hi I am new in ROS. In my program, I am launching a launch file and through which my .cpp file is executing. In this .cpp, I check for a condition, if it doesn't satisfy I have to terminate the program. To terminate this I have tried ros::shutdown() but it not working enough. How should I terminate this.

Thanks a lot for your help.
