Hello all.

I've been trying to get back into ROS but I keep having this issue of roscd not finding catkin_ws. I went as far as removing the catkin_ws folder and copying everything from the Catkin tutorial on how to setup a workspace but still the same results. These are the steps I took:

david@davidsPro3:~$ source /opt/ros/indigo/setup.bash

david@davidsPro3:~$ mkdir -p ~/catkin_ws/src

david@davidsPro3:~$ cd ~/catkin_ws/src

david@davidsPro3:~/catkin_ws/src$ catkin_init_workspace

Creating symlink "/home/david/catkin_ws/src/CMakeLists.txt" pointing to "/opt/ros/indigo/share/catkin/cmake/toplevel.cmake"
david@davidsPro3:~/catkin_ws/src$ cd ~/catkin_ws/

david@davidsPro3:~/catkin_ws$ source devel/setup.bash

david@davidsPro3:~/catkin_ws$ echo $ROS_PACKAGE_PATH

/home/david/catkin_ws/src:/opt/ros/indigo/share:/opt/ros/indigo/stacks

david@davidsPro3:~/catkin_ws$

Once done I opened a new terminal and ran roscd with the results below:

david@davidsPro3:~$ roscd catkin_ws

roscd: No such package/stack 'catkin_ws'

david@davidsPro3:~$ 

david@davidsPro3:~$ roscd

david@davidsPro3:/opt/ros/indigo$

I also did this followed by sourcing

Running command: "make -j4 -l4" in "/home/david/catkin_ws/build"

Thanks for and help and suggestions on why this is not working?

Doesn't roscd only work on package? catkin_ws is a workspace not a package.

Not sure why things were not working originally when I was trying to roscd to beginner_tutorials as I was doing everything in one terminal and I was sourcing at the end. Regardless it is working now (I assume I was mistyping something). Thanks for the assistance.

Check this for roscd. The roscd command works fine. Roscd allows you to change directories using a package name, stack name, or special location.

roscd: No such package/stack 'catkin_ws'

The catkin_ws you are trying to find with the roscd is not a package, but contains packages if you have built some. So if in your catkin_ws/src directory are built packages you can roscd them.

Don't forget, after each build you do at your workspace (catkin_make) to source the devel/setup.bash to have better use of the roscd command.

Hi David!

1) Whenever you open a new terminal you have to run the command:

source ~/catkin_ws/devel/setup.bash

so the current shell knows the address to your catkin_ws. Doing that everytime you open a new shell can be (IT IS) boring. The workaround is adding the forementioned line in the very end of your ~/.bashrc file, as suggested by the ROS tutorial.

1) I believe the roscd command works with packages, not workspaces. Then, let's say you created a package named "tutorial" in ~/catkin_ws/src/ (see the command catkin_create_pkg for package creation), the roscd command would work this way:

~$: roscd tutorial

Hope that helps!

Me too I have some problem with roscd. In .bashrc I have this lines:* source /opt/ros/kinetic/setup.bash source ~/catkin_ws/devel/setup.bash source ~/tutorial_ws/devel/setup.bash But the command "roscd tutorial_ws" doesn't work (I have 2 workspaces catkin_ws and tutorial_ws).

Those are the commands and errors I get in the Terminal: *as@as-Inspiron-1545:~$ echo $ROS_PACKAGE_PATH /home/as/tutorial_ws/src:/opt/ros/kinetic/share as@as-Inspiron-1545:~$ roscd tutorial_ws roscd: No such package/stack 'tutorial_ws' as@as-Inspiron-1545:~$ roscd catkin_ws roscd: No such package/stack 'catkin_ws' as@as-Inspiron-1545:~$


If anyone can clarify would be grateful.
