Dear All,

I tried to create a catkin ws using catkin init then enter catkin build and I got the following error:

emeric@emeric-desktop:~/catkin_planning_ws$
ls src hector_navigation  waypoint_ctl
emeric@emeric-desktop:~/catkin_planning_ws$

Besides I do not understand why the workspace is set to /home/emeric and not /home/emeric/catkin_planning_ws ? Because the build and devel directories are created in /home/emeric.

Can you tell me what I am missing here?

Thank you very much

I'm not sure if I got your problem, but, you can init a catkin workspace using this:

First, create a folder where it'll be your workspace folder and your source folder:

$ mkdir -p my_workspace/src

After that, go to my_workspace folder and run it:

$ catkin_make

And done. Now it is just going to src folder and run it:

$ catkin_create_pkg pkg_name roscpp rospy etc

@Teo Cardoso, thank you for your answer, but actually what I do not understand is even if I am using catkin_make, when I look at the messages, I have a workspace : /home/emeric and not /home/emeric/catkin_planning_ws (in my case) - so I have a build and devel space created on my home directory...
