Hello, I run the following commands in my terminal to create the executable "gira":

mkdir -p ~/catkin_ws/src

cd ~/catkin_ws/src

catkininitworkspace

cd ~/catkin_ws

catkin_make

source devel/setup.bash

cd ~/catkin_ws/src

catkincreatepkg beginnertutorials geometrymsgs imagetransport navmsgs roscpp sensormsgs stdmsgs

I copy gira.cpp in beginner_tutorials/src and I add to CMakeList.txt:

addexecutable(gira src/gira.cpp) and targetlinklibraries(gira ${catkinLIBRARIES})

cd ~/catkin_ws

catkin_make

source devel/setup.bash

my ROSPACKAGEPATH is: /home/turtlebot/catkinws/src/beginnertutorials:/opt/ros/groovy/share:/opt/ros/groovy/stacks

rosrun beginner_tutorials gira

And does not find the executable, what am I doing wrong? Thanks for help
