Hi, I am following the tf tutorial.

Maybe because I installed the ninja, there is something different with the tutorial.

after I create the ros package with

catkin_create_pkg learning_tf tf roscpp rospy turtlesim

with catkin make and source dev/setup.bash. then type roscd learning_tf. the terminal led me to


I suppose roscd should led me to /catkin_ws/src/learning, right?

Then everthing is wrong, I can catkin_make or catkin_make_isolate the learning_tf package.

But the launch file will loop into the /install_isolate/share/learning_tf to find the binary files. But there are not in there. (the binary files located in the devel_isolate instead).

Thank you
