rosrun cannot find executables.
I realize this question has been asked to death, but when running rosrun raspicam raspicam_node I get the message [rosrun] Couldn't find executable named raspicam_node below /opt/ros/indigo/share/raspicam.
I am running Raspbian jessie on a Raspberry Pi 2 with ROS Indigo. catkin_make_isolated was used to build the workspace. I placed the following lines in .bashrc:
source /opt/ros/indigo/setup.bash
export ROS_PACKAGE_PATH=/home/pi/ros_catkin_ws/src:/opt/ros/indigo/share:/opt/ros/indigo/stacks
export ROS_WORKSPACE=/home/pi/ros_catkin_ws
Prior to running rosrun, I enter the ros_catkin_ws directory and input source devel_isolated/setup.bash
The executable exists under ros_catkin_ws/devel_isolated/raspicam/lib/raspicam.
If I move the executable to ros_catkin_ws/src/raspicam/src, everything works fine, but I would rather it work without manually moving files.
Output of echo $ROS_PACKAGE_PATH
Before sourcing: /home/pi/ros_catkin_ws/src:/opt/ros/indigo/share:/opt/ros/indigo/stacks
after sourcing: /home/pi/ros_catkin_ws/src/image_transport_plugins/theora_image_transport:/opt/ros/indigo/share:/opt/ros/indigo/stacks
You can try
source devel_isolated/setup.bash --extendinstead. Without the extend flag, the last sourced file overwrites all of the previously loaded ones.If that does not help, please, edit your question and append the output of
echo $ROS_PACKAGE_PATHafter you source your workspace. And another thing - is the executable a Python script? If so, they have custom handling that allows you to run files directly from the source space.I added the output of echo
echo $ROS_PACKAGE_PATHbefore and after sourcing. This is clearly a problem. The script is c++ not Python.I think the
.bashrclines are not correct. Trysource /opt/ros/indigo/setup.bash; source /home/pi/ros_catkin_ws/devel/setup.bash --extend;and do NOT manually setROS_PACKAGE_PATHnorROS_WORKSPACE. And also make sure you've built your workspace withcatkin_makeand try in a new terminal.
