ROS2 build error gazebo_ros_pkgs

edit

I am getting a build error gazebo_ros_pkgs from source for ROS2 Dashing on a (ubuntu 18.04) Jetson Nano hardware.

I build from source Gazebo 9.9.0 and I followed this link to build from source gazebo_ros_pkgs http://gazebosim.org/tutorials?tut=ro...

I am getting the following error below. Appreciate any help !
