R2025a Ros2 Jazzy Ubuntu LIBSTDC++ error help!

Hello,

I am fairly new to ROS2 and Linux in-general, so bear with me. I am trying to update a robotics software stack from a previous version of MATLAB running on Ubuntu 22.04.5 and ROS2 Humble to R2025a MATLAB running on Ubuntu 24.04(.3 i believe, I am writing this away from my computer so apologies) and using ROS2 Jazzy. Additionally, I have the simulink, control system toolbox, MATLAB coder, MATLAB compiler, requirements toolbox. ROS toolbox, and simulink coder toolboxes installed.

I have gotten R2025a installed withinUbuntu 24.04, as well as ROS2 Jazzy, onto a virtual machine through Quickemu. However, recently I have been stuck on the following errors and have yet to find a working solution.

First, I got a few unrecognized custom message type errors which I attempted to fix by utilizing ros2genmsg, and then refresh_custom_msgs, but was then hit with the following –

>> refresh_custom_msgs

I have tried installing new GCC versions but to no avail, alongside many other things. Any help would be greatly appreciated!

It would be of interest to put a breakpoint at line 73 of ros.internal.utilities.checkAndGetCompatibleCompilersLocation and check to see what was stored in matlabLIBSTDCXXVersionNum
