PX4 SITL with Gazebo Harmonic — error loading libGstCameraSystem.so and EKF2 missing data

PX4 Autopilot
1

Hello! I have a question about PX4 SITL. I’ve completed the Toolchain installation, and setup PX4 with the no-sim-tools option cause I’ve already installed Gazebo Harmonic, and when I run “make px4_sitl gz_x500“ I get an error and some warnings.

Error:

[Err] [SystemLoader.cc:92] Failed to load system plugin [libGstCameraSystem.so] : Could not find shared library.

Warnings:

I am new to using gazebo with PX4-Autopilot and was wondering what can I do to solve these errors.

I am using ubuntu 24.04.5 LTS, ROS2 Jazzy and Gazebo Harmonic. Thank you!

Can you try with main? Before building run make distclean

I switched to the main branch (I was already on it), make distclean, pulled and then make px4_sitl gz_x500 and unfortunately there’s no difference :confused:

There might be other things occuring in the sim setup in the install script. Like setting env var paths for resources. I’m not at my computer to check , but if I were you I would use Claude Code to analyze the install script to help you debug the issue.

Thank you, I will try it!

Any luck? I’m running into the same issue.

I’m running Gazebo Jetty. I’ve tried installing and reinstalling PX4 and Gazebo so I may have some artifact in my environment that is now causing problems?
