Incompatible library version (server version: 5, library version: 4) #240

Closed simonbogh closed 2 years ago

simonbogh commented 2 years ago

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:

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 2 years ago

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

The new libfranka version is now on github

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

alison-bartsch commented 2 years ago

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.

marcbone commented 2 years ago

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!
