Build the Workspace
For Jade
I did the following in the Jade environment - when bashrc had the following.
source /opt/ros/jade/setup.bash
mkdir -p ~/catkin_ws/src cd ~/catkin_ws/src/ catkin_init_workspace cd .. catkin_make . devel/setup.bash echo $ROS_PACKAGE_PATH cd src/ catkin_create_pkg follow std_msgs rospy roscpp cd .. catkin_make . ~/catkin_ws/devel/setup.bash
For Indigo
Experiment - setup.bash add this workspace to ROS_PACKAGE_PATH in a particular shell. I did the above the Indigo environment - when bashrc had the following.
source /opt/ros/indigo/setup.bash
echo $ROS_PACKAGE_PATH /opt/ros/indigo/share:/opt/ros/indigo/stacks:/home/eepp/ros_packages . devel/setup.bash echo $ROS_PACKAGE_PATH /home/eepp/catkin_ws_indigo/src:/opt/ros/indigo/share:/opt/ros/indigo/stacks
