The message of the first command (roslaunch usv_sim airboat_scenario1.launch parse:=true) is not an error. It is just an warning that the parsing ended.
Can you verify if there is a hidden folder (named .uwsim) in your home directory? If there isn't, move the folder from usv_sim_lsa to your HOME folder. To do that, just run the following command: mv .uwsim ~
Regards, Marcelo
Following your steps, I finished "Compile the stack". However, when I tried to run a scenario:
roslaunch usv_sim airboat_scenario1.launch parse:=trueThe Terminal reports: ================================================================================*REQUIRED process [scene_to_spawner-2] has died! process has finished cleanly log file: /home/dai/.ros/log/76c6172c-1d54-11e9-80aa-000c29a4b4cb/scene_to_spawner-2.log Initiating shutdown!**Could you please give me some possible suggestions?
Then I have tested another command line:
roslaunch usv_sim airboat_scenario1.launch parse:=falseMore warnings and errors appear:Warning [parser.cc:778] XML Element[wind], child of element[link] not defined in SDF. Ignoring[wind].

The windows of gazebo came out first and shut down auto.
At the real first time, I have once wait to see a 3D simulated scenario with some buoys in two rows.
By the way, the following command line was also not work for me.
./install_usv_sim
