Incompatible library version #310

Closed HukoOo closed 1 year ago

HukoOo commented 1 year ago

Hi,

I have installed franka libraries to Ubuntu 20.04, installed ROS Noetic and libfranka.

When I try to launch in franka_control, I get the following error: [ERROR] [1671433188.939110450]: FrankaHW: Failed to initialize libfranka robot. libfranka: Incompatible library version (server version: 6, library version: 5). Please check https://frankaemika.github.io for Panda system updates or choose a libfranka version that uses the server version 6 from the table at https://frankaemika.github.io/docs/compatibility.html .

version of libfranka and franka_ros are same with 0.10.0

and when I check version in the DESK, I can get following : Version 5.2.1 516a2e7aaa

What might be the problem?

Kind regards, `

You are not using libfranka 0.10.0 (then you would have library version 6). I guess you installed franka-ros over ROS, right? This will also install ros-noetic-libfranka which is version 0.9. I guess that this is shadowing your libfranka 0.10 version. You have to remove the other version of libfranka with "sudo apt remove ros-noetic-libfranka" and then compile franka_ros from source

The ros-noetic-libfranka and compiled libfranka were installed together.

I deleted the noetic-libfranka and solved it.

Thank you.
