When I run catkin_make, talker listener all files are linked and showed build target talker listener 100%. But when i want to run this using rosrun it says "couldn’t find executable named talker". I have changed the code in CmakeLists.txt

Maybe you are missing a path setting. Try the following in your workspace

$ source devel/setup.bash # In bash, run setup.XXXX to match the shell you are using.

I did that. i noticed that listener and talker executable file are being created in build folder. is that okay? Or those file should be created in devel folder?

This is correct. When you build, the executable will be created in build. As a side note, this was during development.

You can set up the installation setting and install the executable elsewhere.

@miura Did you notice the description says he used catkin_make? Therefore, the executable should be somewhere in catkin_ws/devel/lib/.

@Mike Scheutzow Thank you for pointing this out. I must have made a mistake with build and devel.
