make px4_sitl_rtps gazebo delivers Protocol Buffer error

[tamasso-parec]

I'm on Ubuntu 20.04 trying to follow the procedure described in here to work with ROS2. I have ROS2 Foxy installed by following the procedure from the ROS website.

I am performing the Sanity Check and failing at the very first step. I cloned the repository for PX4-Autopilot: git clone https://github.com/PX4/PX4-Autopilot.git --recursive And used the script provided: bash ./PX4-Autopilot/Tools/setup/ubuntu.sh

Once I try to run: make px4_sitl_rtps gazebo

The build fails right away and I obtain an extremely long output that I attach here: Output_error.txt. The first few lines read:

The line: "This file was generated by an older version of protoc which is incompatible with your Protocol Buffer headers. Please regenerate this file with a newer version of protoc. " is recurrent in the error message and I am not sure if that is the source of the error or just a consequence.

Thank You for any help You can give me.
