I just updated one of our robots to 4.2.1 and getting this error with the latest updates when trying to connect ROS to the robot:
Exception: libfranka: Incompatible library version (server version: 5, library version: 4).

Versions:

  • Robot: 4.2.1
  • franka_ros from ROS repo: 0.8.2
  • libfranka from ROS repo: 0.8.0

We are aware of this. There will be an update for libfranka (0.9.0) on github today. You should be able to link this against the franka_ros repo. There will also be an additional update to franka_ros in the beginning of next week.

Good to hear 👍

Will you also push a new deb package and when?

marcbone commented

You mean over the ros package system? Yes, but not today. Also we cannot control when the ros maintainers will distribute it to end-users. This could take a few weeks. However, you can create your own debian package in the meantime:

git clone --recursive https://github.com/frankaemika/libfranka
cd libfranka
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_TESTS=OFF ..
cmake --build .
cpack -G DEB
sudo dpkg -i libfranka-0.9.0-amd64.deb

@simonbogh I assume this ticket is solved for you. Feel free to reopen when the problem persists

I am getting the same exception error currently. Could you post more detailed instructions as to how to ensure the versions are correct? I am selecting the correct robot firmware option of '4' during the installation.

See https://frankaemika.github.io/docs/compatibility.html. In the next version of libfranka you will be displayed this link when you get this error.

Hi, I have built libfranka 0.8.0 in a container and am trying to run the container connected to a robot that runs server version 4 (4.0.2). Technically according to the compatibility document both of these are version 4. However I still get the following error when trying to run the ros control node.

Libfranka: Incompatible library version (server version: 4, library version: 5). Please check https://frankaemika.github.io for panda system updates or choose a libfranka version that uses the server version 4 from the...

Any ideas as to what I may be missing here?

Did you perhaps install it manually via Github and forgot to update its submodule?

I met the same problem and fix the problem by installing it manually via Github.
The reason is pip install only install pre-compiled content. After updating libfranka, you need to compile and package it yourself.

git clone --recurse-submodules git@github.com:pantor/frankx.git
cd frankx
mkdir -p build
cd build
cmake -DBUILD_TYPE=Release ..
make
make install
And install frankx via
pip install .

Problem Solved! Enjoy!
