Hi,

i am trying to generate C++-Code using Embedded Coder and ROS-Toolbox. I am using R2022b in Ubuntu 22.04. ROS Distribution is ROS2 Humble.

But after starting code generation, i receive an error like this:

Error using tlc_c

Could not load LoadLibrary error:

Could not load library LoadLibrary error: /usr/local/MATLAB/R2022b/toolbox/ros/bin/glnxa64/../../../../sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.29' not found

I have already seen some earlier posts on familiar issues but they did not help me.

Does anybody here know a solution?

Thanks!

Hello Mirhad,

You may consider updating MATLAB to R2022b Update 2. This issue should be resolved after updating MATLAB.

Besides, noting that the recommanded Linux OS for ROS Toolbox is Ubuntu 20.04 and Debian 11 for R2022b MATLAB (link to ROS Toolbox Requirement). I would recommand to stick to the recommanded version to have a better user experience unless there is a specific reason not to. :)

Hope this helps,

Josh
