[jazzy] node not starting

[SeapathMaster]

Is this behavior also observed when using SpinVIew?
Camera works in SpinView under Ubuntu 22.04. However, in Ubuntu 24.04 the currently available versions of SpinView don't work.

Describe the bug
I installed the spinnaker-camera-driver under ROS2 Jazzy Jalisco using the standard installation method:
sudo apt install ros-jazzy-spinnaker-camera-driver
As there is no valid version for Spinnaker under Ubuntu 24.04, I followed the instruction to set the driver up for use without Spinnaker SDK. I confirmed the correct setup.
Starting the node, it throws an exception and exits with what(): Spinnaker: System instance cannot be acquired.
The spinnaker-camera-driver works with this camera on another PC with Ubuntu 22.04 and ROS2 Humble and Spinnaker 3.2.0.62 installed.

System details

• operating system/version: Ubuntu 24.04 LTS
• ROS version (please prepend to issue title in square brackets, e.g. [noetic]): ROS2 Jazzy Jalisco
• complete FLIR camera model (e.g. BFS-U3-04S2C-C): BFS-U3-31S4C

I fixed it!
It is necessary to add an environment variable:
export SPINNAKER_GENTL64_CTI=/opt/ros/jazzy/lib/spinnaker-gentl/Spinnaker_GenTL.cti

I'd propose to add this to the script linux_setup_flir or in the installation process, setting the environment variable in the local_setup files of this package, in case it isn't set already.
