Hello, I tried to modify one of those tutorials of `actionlib` and when i do `catkin_make` the output is this:
-- Using these message generators: gencpp;genlisp;genpy
-- Generating .msg files for action control/Control /home/robot/Desktop/gamma/src/control/action/Control.action

The action file contains this:
#Twist defined in action
float64 x_angular
---
float64 y_angular
---
float64 z_angular
---
float64 x_linear
---
float64 y_linear

float64 z_linear
What could be happening here?
Thanks beforehand!
