Hi, I am using ROS Indigo. The problem is very simple. I unset the CMAKE_PREFIX_PATH variable. I source /devel/setup.bash. I get an unwanted prefix /home/<user-name>/devel added to my CMAKE_PREFIX_PATH.

echo $CMAKE_PREFIX_PATH
/home/<user-name>/devel:/home/<user-name>/catkin_ws/devel:/opt/ros/indigo

I didn't do any changes to devel/setup.bash or devel/setup.sh. What could be the cause? and How to avoid it?

Thank you.

I would like to filter named log using its name. I cannot able to find that option in rqt_console. The rosconsole man page mentions, named logs will be output to a logger named ros.<package-name>.<name>. How to view this logger from console? PS: I am using launch scripts.

My launch file spawns a ros qt node. After launching, i tried to quit using ctrl+c, but the ros qt node is not terminating. Few other nodes are also present in the launch file with required == "true", When any of that node terminates, launch process tries to kill the ros qt node, no success in the first attempt, but after that it escalates to SIGTERM and then the node terminates. I tried to check the signal sent by the launch process, by writing a signal handler inside ros qt. But no signal is caught when launch initiates the first kill attempt.

@SL Remy I can create a single launch file for executing multiple modules. But i feel the approach of individual launch files is better than single big launch file.

@SL Remy But few modules requires a common node to run. So if that node is executed by the first launch file, then subsequent launch file terminates it by restarting the same node.

@SL Remy I think of adding separate launch files for each modules. So i can run the modules separately or combined (By executing each launch files in sequence).

Hi, how to check in the launch file (inside the node tag), whether that node is already running?
