I am using ROS Jade on Ubuntu 14.04.

My ROS setup has been working fine, but I recently installed java as required for the openni installation, and installed the openni along with files needed for the kinect camera. Now I have a particular launch file that errors with message of not being able to find the nodes. Here is the output from the launch file:

... logging to /home/billy/.ros/log/17d5e0de-1c3a-11e7-8d67-100ba9588b18/roslaunch-billy-ThinkPad-T420-4123.log

I have properly sourced devel/setup.bash. I have deleted the entire build and devel folders and remade them using catkin_make.

The packages are found using rospack find

billy@billy-ThinkPad-T420:~/catkin_ws$ rospack find serial_port_sender
/home/billy/catkin_ws/src/serial_port_sender

I have verified the build folder has the files after making.

Each of the nodes called in this launch is complied from source (these are my nodes). The launch file for launching the navigation stack is the same folder as this laucnh file and it works as usual.

I have verified the ROSPACKAGEPATH is correct:

billy@billy-ThinkPad-T420:~/catkin_ws$ echo $ROS_PACKAGE_PATH
/home/billy/catkin_ws:/home/catkin_ws:/opt/ros/jade/share:/opt/ros/jade/stacks

The detailed message from the log file may help you understand but I wasn't able to get anything useful from it:

And the content of the launch file is here.

<launch>

<node pkg="xv_11_laser_driver" type="neato_laser_publisher" name="xv_11_node" output="screen">
    <param name="port" value="/dev/ttyUSB0"/>
    <param name="message_logging" value="0"/>
  </node>

  <node pkg="cmd_publisher" type="cmd_publisher" name="cmd_publisher" output="screen">

serial_port_node
  <node pkg="serial_port_sender" type="serial_port_sender" name="serial_port_sender" output="screen">
  </node>

robot_state_node
  <node pkg="robot_state_machine" type="robot_state_machine" name="robot_state_machine" output="screen">
  </node>


</launch>

As noted before, this launch file and the other nodes are unchanged from when it was working.

I can see the the executable files in the devel folder as shown:

billy@billy-ThinkPad-T420:~/catkin_ws/devel/lib/robot_state_machine$ ls
robot_state_machine

but rosrun does not work as shown:

billy@billy-ThinkPad-T420:~/catkin_ws$ rosrun robot_state_machine robot_state_machine[rosrun] Couldn't find executable named robot_state_machine below /home/billy/catkin_ws/src/robot_state_machine
[rosrun] Found the following, but they're either not files,
[rosrun] or not executable:
[rosrun]   /home/billy/catkin_ws/src/robot_state_machine
[rosrun]   /home/billy/catkin_ws/src/robot_state_machine/include/robot_state_machine

I see rosrun isn't looking in the devel folder, but don't know enough about ROS to be sure that's an issue.

What am I missing? Thanks in advance for your help.
