Cannot run the examples launch file

[oruiz97]

I've been taking a look at this package and wanted to launch the example to start experimenting on how to use it. However I have not been able to run it. These have been my steps:

• Cloning the package into a new catkinws/src folder
• Building as stated in the readme catkin_make -DCMAKE_BUILD_TYPE=Release
• source devel/setup.bash
• roslaunch cartesian_controller_examples examples.launch

I am using ROS noetic in a debian machine. This is the error message that I get. Is there a step I am missing? I don't see any further indication of that in the readme.

Error message after launching examples.launch

Hi @oruiz97

[ERROR] [1633938021.095060858]: MultiLibraryClassLoader: Could not create object of class type cartesian_controller_base::ForwardDynamicsSolver as no factory exists for it. Make sure that the library exists and was explicitly loaded through MultiLibraryClassLoader::loadLibrary()

This indicates that the controllers' solver (which is a separate library) cannot be loaded. Could you check the following?

1) After sourcing your devel/setup.bash, what's the output of

rospack plugins --attrib=plugin cartesian_controller_base

2) After navigating into devel/lib/, what's the output of

ldd -d libik_solvers.so

The workspace built correctly, right?

Yes, no errors show up when building

[stefanscherzinger]

@oruiz97 That is somewhat unfortunate. I can't spot anything unusual. If the issue still persists, could you switch-on debug logging for the sim_hardware_interface? Maybe the whole process of loading the libraries gives more insight. I think this can be activated in rqt with Plugins -> Logging -> Logger level.

[Mohatashem]

Hello, I also tried launching the examples.launch file exactly as done by @oruiz97. I am using Ubuntu 18.04 and ROS-Melodic.

The terminal has the following output:

... logging to /home/pp1744/.ros/log/f93e2b80-4390-11ec-83f3-d03c1fd5e0d5/roslaunch-pp1744-Precision-5550-9747.log

On trying to swtich on the debug-logging for sim_hardware_interface in rqt the 'Loggers' and 'Level' sections are blank, while the terminal displays the following:

During get_service_class_by_name "/sim_hardware_interface/get_loggers":
Unable to communicate with service [/sim_hardware_interface/get_loggers], address [rosrpc://pp1744-Precision-5550:36991]

I am not sure how to proceed from here. Any ideas/suggestions are appreciated. Thank you.

[sim_hardware_interface-1] process has died

I guess at that point we need to go into debugging this thing. If you find some time, could you do the following?

1. Build your workspace with debug symbols:

   catkin_make -DCMAKE_BUILD_TYPE=Debug

2. Create a .gdbinit file in your home folder, if not already existent, and add the following:

   set pagination off

   This is helpful when spawning the node in gdb later so that you don't have to hurry before the controller manager times out.

3. Start the examples launch with debugging enabled:

   roslaunch cartesian_controller_examples examples.launch debug:=True

   This will start the sim_hardware_interface in gdb inside a screen session. It personally like that approach to pick-up the screen session in a terminal of my choice.

4. In some terminal, call

   screen -r

   This will get you inside gdb. When the program crashes, type backtrace. Could you post that output here?

[Mohatashem]

Hello, Thank you for the response. Here is the output of from screen -r followed by backtrace when the program crashes:

[stefanscherzinger]

@Mohatashem Thanks for providing the detailed output and thanks for investing your time!

That is really weird. It is still successful in constructing a boost::filesystem::path with the parent folder of the ik_solver_plugin.xml file (see code here, scroll to line 524).

However, it later fails in checking if the package.xml file in that same directory exists. But instead of just returning false, it segfaults. That's really weird.

Could you check what's going on in the following directory?

ls -l /home/pp1744/rosworkspaces/cartesian_control_test_ws/src/cartesian_controllers/cartesian_controller_base/

And get the sha1 checksum of the package.xml file?

sha1sum package.xml

Mine (master freshly downloaded) is: 163a1ad0fd56228d2e772077dd166d10bb354fb3 package.xml

[stefanscherzinger]

Thanks @Mohatashem

I'm really not sure what's happening here. Could you switch to the replace-boost-with-std branch, completely remove build and devel folders and rebuild? I replaced boost functionality with the standard in the hope of removing possible pitfalls with user-side Boost versions.

If that's not solving the issue, I need to find a way to reproduce this myself on Melodic for further debugging.

[stefanscherzinger]

@Mohatashem Did you make progress on this?

---

Edit: Please use the latest master branch.

[Mohatashem]

@stefanscherzinger Pardon me for the delayed reply. I had tried with the replace-boost-with-std a few days ago but couldn't get to reply to you. But nothing changes. I even tried the steps you mentioned for debugging and compared the terminal outputs to the older ones. the errors stay the same. I still can't seem to figure out what's wrong.

The same holds true with the latest master branch. I just tried it as well.

One additional thing, I am not sure it if it is related, but in every try so far, as the Rviz starts, the RobotModel also throws an error. See attached screenshot:

[stefanscherzinger]

@Mohatashem Thanks for the fast reply! Before continuing, could you confirm that you completely deleted both your devel and build folder?

[Mohatashem]

@stefanscherzinger Yes, of course, that's what i did before rebuilding.

[stefanscherzinger]

@Mohatashem Alright, thanks for clarifying this.

Your remark on RViz is interesting. ros_control_boilerplate should at least come up with the joint_state_controller, which should publish the joint_states for the robot_state_publisher to complete the TF tree. And the model should look normal in RViz. Maybe that points us to something general not working.

Could you outcomment the controller spawner in the launch file? Something like

        <!-- Spawn controllers -->
        <!--
        <node name="controller_spawner" pkg="controller_manager" type="spawner"
                args="- -stopped
                my_cartesian_motion_controller
                my_cartesian_force_controller
                my_cartesian_compliance_controller
                my_motion_control_handle
                my_joint_to_cartesian_controller
                joint_trajectory_controller
                "
        />
        -->

Note the whitespace in - - stopped to keep valid xml syntax.

Don't run it in debug mode for this. Use the normal mode. Let's see if this minimal setup without the cartesian_controllers works.

[stefanscherzinger]

If that doesn't change anything in RViz, which I assume, maybe some further dependencies are missing. Could you run this in the terminal where you normally build the workspace

rosdep install --from-paths src --ignore-src -y -s

and paste the output here? The -s flag only simulates the install instead of actually doing it. Then we can check if something is missing.

[Mohatashem]

@stefanscherzinger

Could you outcomment the controller spawner in the launch file? Something like

Yes, when I comment it out, the RobotModel loads fine:

And the terminal output now does show that the joint_state_controller is loaded. This is the last part of the shell:

I have not yet ran rosdep install --from-paths src --ignore-src -y -s as Rviz model seemed ok, should I still run it?

[stefanscherzinger]

@Mohatashem

[my_joint_to_cartesian_controller/controller_spawner-5] process has finished cleanly

That shouldn't load. Make sure that you do not spawn any of the controllers from the cartesian_controllers package.

But it's interesting that RViz shows the model fine.

I have not yet ran rosdep install --from-paths src --ignore-src -y -s as Rviz model seemed ok, should I still run it?

Yes, please. Let's see what that says.

[Mohatashem]

@stefanscherzinger

That shouldn't load. Make sure that you do not spawn any of the controllers.

Okay. Just to clarify, I had commented out only this i.e. the whole node tag. Now I also commented out the this i.e. everything within the group tag. The model in rviz loads fine I left this one uncommented because without it the Rviz model does not load as before.

Could you run this in the terminal where you normally build the workspace

rosdep install --from-paths src --ignore-src -y -s

No output returned, I wonder if I am doing anything wrong

pp1744@pp1744-Precision-5550:~/rosworkspaces/cartesian_control_test_ws$ rosdep install --from-paths src --ignore-src -y -s

@Mohatashem

Yes, thanks, that's right.

That's good. That means that all dependencies are already installed.

Could you now launch that stuff again with debug:=True (leaving the parts outcommented) And open rqt with the controller manager plugin?

After loading the my_cartesian_motion_controller (richt klick -> load), could you again post the output you get from the backtrace in screen from gdb?

Let's see if that again segfaults somewhere in pluginlib.

This appears exactly when I right click->load my_cartesian_motion_controller

[stefanscherzinger]

@Mohatashem

Thanks again for going through all this! It again points to some corruption from frame #2 downwards. If I were to provoke this myself, I would build and link pluginlib as a shared object to the boost system dependencies and then change the boost version to run into some ABI incompatibilities.. But on Melodic, pluginlib hasn't changed since February last year and Boost 1.65.1 seems to be the default for Bionic... weird.

As a last thing to try just in case, could you get pluginlib and build that inside the ROS workspace with the cartesian_controllers from source?

Build with debug symbols enabled:

catkin_make -DCMAKE_BUILD_TYPE=Debug

Does that reproduce the same segfault when loading the my_cartesian_motion_controller?

---

Edit: I checked the CI for Melodic and that successfully uses pluginlib version 1.12.1, which differs from the recent version 1.12.2. Before building pluginlib from source, could you check your version with

rosversion pluginlib

[Mohatashem]

@stefanscherzinger On my system the pluginlib version is 1.12.1

Again just to be sure, I am doing everything correctly, this is what I did:

1. Cloned the pluginlib (same version) to src folder of my workspace.
2. deleted the build and devel folders.
3. ran catkin_make -DCMAKE_BUILD_TYPE=Debug

Kindly, let me know did I miss anything in the steps, so far?

Moving on,

I repeated what we have done so far. I received the same segfault just as I load the my_cartesian_motion_controller:

[stefanscherzinger]

@Mohatashem Thanks for all the information.

Kindly, let me know did I miss anything in the steps, so far?

No, that was alright. I wanted to test exactly what you did. The idea was to see if we had ABI inconsistencies. They would've gone away by relinking pluginlib against the system Boost dependency. But that's not it. Unfortunately I'm running out of ideas to guide you remotely through this thing without wasting too much of your time.

there are some warnings. Wonder whether they are useful:

I wouldn't think so, no. What keeps irritating me is this in the backtrace (frame #3):

ik_solver_plugin.xml", classes_available=std::map with 0 elements)

I would expect 4 classes instead.

I'll try if I can reproduce the whole thing somehow on Melodic myself and let you know.

[stefanscherzinger]

@Mohatashem

There's one thing you could do. Could you provide the CoreDump file of the segfault? That would allow us to have a look at the exact memory state when the program crashed.

That would be like (I hope this works on 18.04):

1. Restore the examples.launch file, i.e. start everything like from a clean git clone.
2. Also remove pluginlib from the src folder
3. Remove build and devel
4. Build your workspace with debug symbols
5. In the terminal where you call roslaunch, call ulimit -c unlimited. This will allow to create core files
6. Launch everything in that terminal and wait for the segfault
7. End all ROS-related processes
8. Navigate to /var/crash and find the .crash file of the segfault
9. Unpack that to a temporary folder with apport-unpack your-crash-file tmp_folder
10. Attach the CoreDump file from the tmp_folder here to this post.

I can then debug with gdb using that core file.

[Mohatashem]

@stefanscherzinger

Unfortunately I'm running out of ideas to guide you remotely through this thing without wasting too much of your time.

No problem at all. I do understand it and I thank you so much for your time and help. I really appreciate it. As a last attempt, I have attached the file. Here is it CoreDump.zip

[stefanscherzinger]

@Mohatashem

Thanks, but that's unfortunately not the right one. Was there some other ..crash file? Something with ros_control_boilerplate_sim_hw_main or similar in its name?

We want to find the core dump for this executable:

Thread 6 "sim_hw_main" received signal SIGSEGV, Segmentation fault.

You can check the core file with the file command. The attachment gives me:

file CoreDump
CoreDump: ELF 64-bit LSB core file, x86-64, version 1 (SYSV), SVR4-style, from 'python /opt/ros/melodic/lib/rqt_controller_manager/rqt_controller_manager', real uid: 1000, effective uid: 1000, real gid: 1000, effecti
ve gid: 1000, execfn: '/usr/bin/python', platform: 'x86_64'

Additionally, could you also append the libcartesian_motion_controller.so? It should be in devel/lib/. I will be needing that for the symbols. They are normally not included in the core file.

---

Edit: The core file might also be located under /var/lib/apport/coredump.

[Mohatashem]

@stefanscherzinger Sorry for the delayed reply. For some reason, I don't seem to be getting a crash file with ros_control_boilerplate_sim_hw_main name. I started anew and everything. However I realized that in my latest try Thread 6 "sim_hw_main" received signal SIGSEGV, Segmentation fault. does not appear in the launch terminal, it only appears in the terminal of screen -r (where we do the backtrace). Even then, I couldn't find any such crash file (my /var/crash and /var/lib/apport/coredump) are both empty.

I will retry it again maybe later or tomorrow and get will surely get back to you if it is alright?

One other thing, I would like to mention is that I cloned the repo on two other systems with melodic installation and there it worked flawlessly, which is weird for me, given I usually test everything on this system before installing dependencies (if required) on the other system and deploying.

[stefanscherzinger]

@Mohatashem

it only appears in the terminal of screen -r (where we do the backtrace).

Oh, right. I forgot to mention. Please launch it normally for creating the core file. No debugging. Remember to set ulimit -c unlimited in the terminal where you launch everything. A SIGSEGV triggers a core dump. At least it just did on my 20.04 when sending a kill -11 to the process of my running sim_hw_main. gdb seems to swallow that.

will surely get back to you if it is alright?

Yes, I would like to get to the bottom of this specific problem. It might also be relevant for other people.

I would like to mention is that I cloned the repo on two other systems with melodic installation and there it worked flawlessly

That's good to hear! It also agrees with the integration test for Melodic of this repo.

[Mohatashem]

@stefanscherzinger I am really sorry, for some reason, I still cannot see the SIGSEGV triggering a core dump. Both the folders you mentioned in var are empty. Let me list the steps I followed just in case I skipped something:

1. Starting a new, I git cloned everything to src
2. I built the workspace using catkin_make -DCMAKE_BUILD_TYPE=Debug
3. Sourced the workspace source devel/setup.bash
4. Called ulimit -c unlimited in a terminal
5. roslaunch cartesian_controller_examples examples.launch in the same terminal as step 4.

I do see that [sim_hardware_interface-1] process from ros_control_boilerplate dies, but I cannot see core dump.

6. I kill the terminal to close the ROS related processes.

But there is something interesting. Here is the 'error' part from the terminal where the launch file was launched:

Edit: PFA libcartesian_motion_controller.zip

[stefanscherzinger]

@Mohatashem

Ok, let's take a different approach for creating the core file. We can do that also in gdb (I just found that out). Try to follow these steps:

1. Build your workspace with debug symbols as before
2. Launch the examples.launch file with debug:=True
3. Pick-up the screen session as before and wait for the segfault
4. In gdb, check the current directory with pwd. That's were the core file will be saved to
5. In gdb, call gcore. This will create a core file
6. Exit gdb
7. Get the core file and upload it here.

When doing that on my system, the core files from gdb end up in ~/.ros in my home directory.

Edit: PFA libcartesian_motion_controller.zip

Thanks for uploading the symbol file!

[Mohatashem]

@stefanscherzinger Thank you so much! Please find attached. If possible also kindly share any resources/link where you learnt how to debug in this manner. I am fairly new to all this core.zip

libcartesian_motion_controller.zip

[stefanscherzinger]

@Mohatashem

I had a look at the core file and there's something that might indicate a clash with two Boost installations.

Using your core file, I did the following:

1. Setup a fresh Ubuntu 18.04 in VirtualBox
2. Installed ROS (ros-melodic-desktop-full)
3. Loaded the symbols of libcartesian_motion_controller.so and the core-file
4. Checked that gdb found the relevant symbols

Step 4. included to put libcartesian_motion_controller.so into /home/pp1744/rosworkspaces/cartesian_control_test_ws/devel/lib, which I created to mimic your setup.

Going through the stack frames, I noticed that your setup uses /usr/local/include/boost/filesystem/operations.hpp, whereas a freshly installed Ubuntu 18.04 with Melodic uses /usr/include/boost.... This indicates that you have a second, non-default Boost installation under /usr/local/include. However, this include is linked against the default Boost library /usr/lib/x86_64-linux-gnu/libboost_filesystem.so.1.65.1 instead of against the local library (probably somewhere in /usr/local/lib).

To test whether this is in fact the problem, you could try two things:

1. Use the Ubuntu 18.04 default Boost installation
2. Or consistently use your second Boost installation (but don't mix them)

This answer in the ROS wiki explains how to do that.

For enforcing the default installation (1.), it might be easiest to remove your additional Boost installation under /usr/local.

For enforcing your additional installation (2.), you could probably remove build and devel and rebuild with

catkin_make -DBOOST_ROOT=/usr/local -DBoost_NO_SYSTEM_PATHS=ON

[Mohatashem]

@stefanscherzinger Yes, indeed. I first tried 2., but the I had the same issues. Then following suggestion 1.I simply removed the additional installation. And now it works fine. I have no idea how the additional installation got there in the first place. I really appreciate the time you took for helping me out on this. You've my deepest gratitude. Thank you so much!

[stefanscherzinger]

@Mohatashem You are welcome! And thanks again for hanging in there for so long and your continuous interest in getting this fixed!
