robot_interface_simulator.launch doesn't find industrial_robot_simulator node

[cschindlbeck]

I get the following error for

$ roslaunch industrial_robot_simulator robot_interface_simulator.launch 
ERROR: cannot launch node of type [industrial_robot_simulator/industrial_robot_simulator]: can't locate node [industrial_robot_simulator] in package [industrial_robot_simulator]

You are probably using the package compiled from sources; make sure you have sourced the setup.bash file after compiling the package:

source $HOME/my_catkin_workspace/devel/setup.bash

[cschindlbeck]

i have done that, still not working

[gavanderhoorn]

Based on your reply to @VictorLamoine's question, I'm guessing you have a checkout of industrial_core in your catkin workspace? Have you built the workspace after cloning the package? Are you using regular catkin_make, or catkin_tools?

In general when reporting these kinds of problems (which is great, thanks for that), it's good to include as much information as possible. Especially build environment and steps to reproduce.

I use ubuntu 14.04 with ROS-indigo, industrial_core is built from source with catkin_make (no errors) git branch is indigo-devel with "Already up-to-date" Folder structure

├── catkin_ws
|   ├── devel
|   ├── build
|   └── src
|        ├── industrial_core
|        └── my_other_pkges

i have included

source /opt/ros/indigo/setup.bash
source /home/my_name/catkin_ws/devel/setup.bash

in the bashrc file

[gavanderhoorn]

Just did the following on a clean Trusty docker container:

# usual ROS apt sources, keys, etc
$ sudo apt-get install ros-indigo-ros-base

$ mkdir -p ~/catkin_ws/src
$ cd ~/catkin_ws/src

$ git clone https://github.com/ros-industrial/industrial_core.git
$ rosdep update
$ rosdep install --from-paths ~/catkin_ws/src --ignore-src

$ cd ~/catkin_ws
$ catkin_make

$ source ~/catkin_ws/devel/setup.bash

Finally:

$ roslaunch industrial_robot_simulator robot_interface_simulator.launch

It seems this is working for me.

Can you list the exact steps you take to reproduce what you are seeing?

[gavanderhoorn]

i have included

source /opt/ros/indigo/setup.bash
source /home/my_name/catkin_ws/devel/setup.bash

in the bashrc file

Ignoring the double source there, lines in your .bashrc are only executed when you start a new instance of bash (fi by starting a new terminal, or opening a new tab), or when you explicitly source ~/.bashrc. If you didn't do either of those after building your workspace, you could run into the problem you reported.

[cschindlbeck]

I have installed sudo apt-get install ros-indigo-desktop-full Might this cause the problem?

I get the following error massage after

$ rosrun industrial_robot_simulator industrial_robot_simulator

[rosrun] Couldn't find executable named industrial_robot_simulator below /home/my_name/catkin_ws/src/industrial_core/industrial_robot_simulator
[rosrun] Found the following, but they're either not files,
[rosrun] or not executable:
[rosrun]   /home/my_name/catkin_ws/src/industrial_core/industrial_robot_simulator
[rosrun]   /home/my_name/catkin_ws/src/industrial_core/industrial_robot_simulator/industrial_robot_simulator

[gavanderhoorn]

Also (but maybe unnecessary): if you can, please just use the released, binary distribution of industrial_core: those are known to work, and avoid all kinds of problems wrt dependencies and workspace layouts.

[cschindlbeck]

This fixed the problem:

chmod +x industrial_robot_simulator

[gavanderhoorn]

I have installed sudo apt-get install ros-indigo-desktop-full

Might this cause the problem?

No. It's probably a build thing.

I get the following error massage after $ rosrun industrial_robot_simulator industrial_robot_simulator ...

How did you clone the repository?

What is the output of:

ls -al /home/my_name/catkin_ws/src/industrial_core/industrial_robot_simulator/industrial_robot_simulator

[gavanderhoorn]

chmod +x industrial_robot_simulator

The fact that you need to do that points to problems with how you downloaded the sources. It'd be nice if you could tell us exactly what you did.

[cschindlbeck]

if i recall correctly (it has been a while actually)

cd catkin_ws/src
git clone https://github.com/ros-industrial/industrial_core.git
cd ../
catkin_make

Will i run into more of these problems with rights? Is sudo git clone the way to go?

[gavanderhoorn]

Is your catkin_ws on a non-Linux fs by any chance? Are you syncing dirs/files using dropbox/megasync/something else?

git clone .. should preserve permissions, and the files in the repository contain the proper permissions, so normally this should not be a problem.

[cschindlbeck]

Actually i use a vanilla Ubuntu 14.04.4, no dropbox or anything related to windows. I deleted the folder and cloned again, now it works, i probably messed up the initial clone process

thanks!

[gavanderhoorn]

Ok. Good to hear it works for you as well now.
