Hello,

I just installed ROS and I'm following the beginner tutorial to get familiar with ROS. I've done until step 4 in "Creating a ROS msg and srv", I don't have any problem in the previous steps but when I try "catkin_make" it fails and I can't find the problem. Thank you for your help. Cheers, Carlos This is the message returned in the terminal:
