Hello,

I have tried to run talker.cpp file, and after running catkin_make and source the source ./devel/setup.bash. while running rosrun beginner_tutorials talker , I got following error.

~/catkin_ws$ rosrun beginner_tutorials talker
[rosrun] Couldn't find executable named talker below /home/meghana/catkin_ws/src/beginner_tutorials

Have you edited the CMakeList.txt file in order to create the executable?

could you include the log of the catkin_make? Maybe it wasn't built correctly. Also make sure that you are sourcing your catkin_ws correctly. Try source /home/meghana/catkin_ws/devel/setup.bash

Did you make the talker node? I'm assuming that you're going through the tutorials from the wiki?
