@bozkurthan exactly, this is how I got it to work. @hamishwillee Here is what I meant by
sudo: The error in the code above is caused by the fact thatlibgazebo_gst_camera_plugin.sogazebo model or its px4 mixers are missing. This can be caused by one of the following reasons:The entire model located at
Firmware/tools/sitl_gazebo/models/typhoon_h480/is missing or is not added to$GAZEBO_MODELS_PATHand$GAZEBO_PLUGIN_PATH. The solution is to make sure you have them under the specified directory and addexport GAZEBO_...commands to your~/.bashrcto make sure nothing override them.A symlink between your built folder directory
/Firmware/build/posix_sitl_default/tmp/rootfs/etcand the directory containing the model’s mixers located at/Firmware/ROMFS/px4fmu_common/init.d-posix/6011_typhoon_h480was not created due to the lack ofsudoprivileges, which was indicated by the shared error message below. A simple fix is to create those links only once usingsudoand then the warning message can be neglected and won’t result in your code termination. Another solution is obviously to create that link manually.Side note: most of the installation instruction for px4 assumes that you are the
sudouser, for example, you would see something like “install the pacakge:apt-get install blablabla”, with nosudo. – Haya
