Rviz crashing while trying to create target

[VictorGiraud]

Rviz crash when I try to create targets.

How to reproduce :
roslaunch ur10_moveit_config demo.launch
Add the handEyeCalibration of moveit_calibration gui
Either click on create target button or add an image topic

The error printed :

[rviz_softmanbot_HP_Z2_Tower_G5_Workstation_104184_6014999650425201243-4] process has died [pid 104204, exit code -11, cmd /opt/ros/noetic/lib/rviz/rviz -d /home/softmanbot/catkin_ws/src/fmauch_universal_robot/ur10_moveit_config/launch/moveit.rviz __name:=rviz_softmanbot_HP_Z2_Tower_G5_Workstation_104184_6014999650425201243 __log:=/home/softmanbot/.ros/log/e40cab08-a9b9-11ec-9038-99fad0a21714/rviz_softmanbot_HP_Z2_Tower_G5_Workstation_104184_6014999650425201243-4.log].

I also cannot find the related log file, as described by other users here
https://answers.ros.org/question/53108/cannot-find-log-files/

I tried debugging, it seems to be the call of
board->draw(image_size, image, separation_, border_bits_)
that crashes (handeye_target_arucco.cpp, line 158)

Ubuntu 20.04 is used with Noetic. Moveit built from sources.

Found the issue : Opencv version conflict, as described here :
https://answers.ros.org/question/289090/how-to-specify-my-own-opencv3-for-cv_bridge/

Couldn't make it work with my opencv source build, so I uninstalled it, build moveit and reinstalled. Seems to work.

@VictorGiraud glad things worked out for you. Would you like to close the issue?

@VictorGiraud glad things worked out for you. Would you like to close the issue?

I think so, although it might need a fix or a compilation warning, this is some really niche case.

Hi,

I have the same issue, but I don't want to mess with my opencv installation since it's connected to so many other things on my workstation. Is there any other fix to this?

Everything else seems fine. I'm able to find the target, collect samples by moving the robot around, but the minute I take the 5th sample, it crashes with the following error:

[rviz_Whisler_196549_2156718789477154300-10] process has died [pid 196622, exit code -11, cmd /opt/ros/noetic/lib/rviz/rviz -d /home/user/catkin_ws/src/fmauch_universal_robot/ur3e_moveit_config/launch/moveit.rviz __name:=rviz_Whisler_196549_2156718789477154300 __log:=/home/user/.ros/log/0a010c50-0775-11ed-b89e-bf81ec93277c/rviz_Whisler_196549_2156718789477154300-10.log].

The error is uninformative and so are the logs connected to this. This is my setup:

On the HandEye Calibration window, I tried using "manipulator" as the planning group, and just to test, "endeffector" as planning group and both fail with the same error. Please help. Thanks in advance.

-11 means it is segfaulting. Can you get a stack trace?

Hi @tylerjw ,

I tried looking through all the log files to get some clue about this, but there's no file by this name "rviz_Whisler_196549_2156718789477154300-10*.log" that shows up in this error. I tried to generate it multiple times, but in vain.

I tried running it in gdb, but then the rviz gui won't open, defeating the whole purpose. I also tried obtaining core dumps as mentioned here, but I don't see any /home/.ros/core files or folders. Kindly help.

[tylerjw]

Here are some better instructions for getting back traces: https://navigation.ros.org/tutorials/docs/get_backtrace.html

The reason you are not getting core dumps is you probably haven't enabled them. You can do that with this command:

ulimit -S -c unlimited

@tylerjw , I was finally able to get some backtrace with gdb. This is right after it crashes:

@tylerjw it works now!! :D

This is the problem. The fix mentioned in that comment worked perfectly!

You may close this issue, but I would suggest updating the readme or something. Thanks for all the help! :)

[tylerjw]

Oh, cool.

Hi @tylerjw ,

I have the same issue here. The rviz crashed after I selected the image topic. The different thing is my OS is ubuntu18 and it doesn't have buggy library libopenblas. And here is my backtrace with gdb.

Hey did anyone solve this issue by any chance ?
