Maybe it could be a stupid question, but did you created the folder with catkin_create_pkg
before?
As explained in the tutorial, it is supposed you created that folder with that command.
If you used mkdir
or something like that, ros will never recongize the right folder.
And don't forget the source devel/setup.bash
if you didn t automate the process after building your code.
EDIT:
It didn 't recognize the package in your catkin environment (your screenshot).
Please be sure that a
CMakeLists.txt
is in your beginner_tutorials
package and is correctly written. Then go into your workspace:
daniel@daniel-G74Sx:~$ cd catkin_ws
and run the command catkin_make
again.
Later on source the file devel/setup again.
It semms to me you are trying to launch the launch file from your home directory and not from the catkin workspace
can you post the command you are using; did you save the
turtlemimic.launch
file in launch folder ?screenshot of the problem
Have roscore running, made the source of setup.bash, beginner_tutorials is recognized as a package and roslaunch gives that error, any help?
