Unable to run rviz in ubuntu 20.04.02 noetic due to error in accessing library

edit

Thank you, this launches rviz but it doesn't allow me to add the model in it.

it doesn't allow me to add the model in it.

Can you describe the steps followed by you to add the robot model into the rviz?

You are using move it packages or loading model using xacro file to view into rviz?

I'm able to launch rviz and load robot model from xacro file directly. When i use moveit to launch rviz model i get the above error: /opt/ros/noetic/lib/rviz/rviz: symbol lookup error: /opt/ros/noetic/lib/libmoveit_dynamics_solver.so.1.1.0: undefined symbol: _ZNK3KDL6Vector4NormEv

Steps followed to setup move it configuration is same as that should in this link http://docs.ros.org/en/kinetic/api/mo... but im using kuka urdf file for this.

I think you are using the wrong tutorials. 1. Try to use Ros noetic tutorials for moveit. 2. Use Xacro file instead of urdf file.

And if you want to directly launch your xacro model then follow the below step.

Follow this steps:

<launch>

          <arg name="model" default="$(find kuka_kr16_support)/urdf/__CHANGE__XACRO__FILE_NAME__"/> 
          <arg name="gui" default="true" />
          <arg name="rvizconfig" default="$(find urdf_tutorial)/rviz/urdf.rviz" />

          <param name="robot_description" command="$(find xacro)/xacro $(arg model)" />

          <node if="$(arg gui)" name="joint_state_publisher" pkg="joint_state_publisher_gui" type="joint_state_publisher_gui" />
          <node unless="$(arg gui)" name="joint_state_publisher" pkg="joint_state_publisher" type="joint_state_publisher" />
          <node name="robot_state_publisher" pkg="robot_state_publisher" type="robot_state_publisher" />
          <node name="rviz" pkg="rviz" type="rviz" args="-d $(arg rvizconfig)" required="true" />

        </launch>

Make a launch file in which robot you want to launch and change xacro file and try to launch this file.

For more details about this try to have urdf basic tutorials given in below link.

Hello @niranjan,

I think you should raise the new question with the move-it tag.
