Can't start Mapviz(process died)

[Nomad-Learner]

Hi, the problem is mapviz is died on start without gui appear. My ROS is noetic, ubuntu 20.04 - WSL Is there any need for predefined config file for mapviz, does it make default on start? It seems mapviz can't load, but I'm not sure if this is the only reason. My command: roslaunch mapviz mapviz.launch

output process[rosout-1]: started with pid [4802] started core service [/rosout] process[mapviz-2]: started with pid [4808] /opt/ros/noetic/lib/mapviz/mapviz: error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file or directory process[initialize_origin-3]: started with pid [4810] process[swri_transform-4]: started with pid [4811] [mapviz-2] process has died [pid 4808, exit code 127, cmd /opt/ros/noetic/lib/mapviz/mapviz name:=mapviz log:=/home/matbi/.ros/log/924327e2-91b5-11eb-9740-2cf05d3f275f/mapviz-2.log]. log file: /home/matbi/.ros/log/924327e2-91b5-11eb-9740-2cf05d3f275f/mapviz-2*.log

The line

error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file or directory

seems to indicate you do not have the required Qt libraries installed. I suspect getting it to run in WSL might take some additional steps, but I'm not very familiar with it. Are you able to run other ROS graphical tools, like RViz?

Thank you for answer I solve the problem to use sudo strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 this command

now I can see mapviz gui

but the other problem is coming

[ERROR] [1617151593.749201500]: "map" passed to lookupTransform argument target_frame does not exist.

I can't understand what the program wants

The "map" is a tf frame that Mapviz uses to transform points from one coordinate frame into another. The standard ROS tf frames are described in https://www.ros.org/reps/rep-0105.html. In your case, the word "map" is likely the default value in the top left box that says Fixed Frame. Mapviz is basically asking for a tf frame with the name "map" to be published (because this is the frame Mapviz is trying to render the data into). If Mapviz is listening to to any data topics (marker arrays, point clouds, odometry messages), you will need to publish tf frames that link the frame id of these incoming messages to the Fixed Frame in mapviz. To learn more about tf frames, and publishing them you can look at http://wiki.ros.org/tf/Tutorials.

[jgassaway]

As a super simple "fix" to just publish a map frame and a fixed odom frame, you could run a static tf publisher: The args are: static_transform_publisher x y z yaw pitch roll frame_id child_frame_id period_in_ms

$ rosrun tf static_transform_publisher 0 0 0 0 0 0 map odom 10

This will publish a tf link with the map frame as a parent, and odom as a child, with no rotation or translation between them, at 10 Hz. Normally, this map to odom frame publishing is handled by some form of odometry measurement (wheel encoders, visual odom) for robotics endeavors, but it might help you get started.

thank you so much answering! I will try again.

@Nomad-Learner I'm curious if you managed to get everything working like you wanted.

@danthony06 I reinstalled my WSL but I cant handle my problem so I installed VMware. In Vmware, mapviz works very good Now things went well. Thank you for answering
