can't run zed ROS wrapper sample

hey,
I wrote this comment under another topic but it seems better to write it separately here…
I am trying to view the depth map using zed ROS wrapper program but I am getting an error.
I followed the Jetsonhacks tutorial on youtube and also the steps on GitHub but I can’t get the depth map
what may be the problem?

this is the steps that I did:

ubuntu@tegra-ubuntu:~$ mkdir catkin_ws
ubuntu@tegra-ubuntu:~$ cd catkin_ws
ubuntu@tegra-ubuntu:~/catkin_ws$ ls
ubuntu@tegra-ubuntu:~/catkin_ws$ mkdir src

Hi HAMDA_ALA,

I saw you also post question in following topic:
https://devtalk.nvidia.com/default/topic/779315/jetson-tk1/jetson-tk1-opencv-and-ros/3

Would you please help to confirm the ROS and OpenCV have been installed well? Any other application can be launched normally?

Thanks

sudo apt-get install ros-indigo-tf
source ~/catkin_ws/devel/setup.bash

^ you can add that line to your .bashrc file. so you dont have to source the workspace everytime you open a new terminal

After you do those two, catkin_make again and the problems listed above should be resolved
