Error when building PX-Ardupilot in Ubuntu 20.04 #858

Closed argenos closed 1 year ago

argenos commented 2 years ago

I'm seeing some errors similar to those reported in #699 at installation time. I am following the instructions from this wiki.

The relevant error that shows up at the make px4_sitl_default gazebo step:

[Err] [Model.cc:1157] Exception occured in the Load function of plugin with name[mavlink_interface] and filename[libgazebo_mavlink_interface.so]. This plugin will not run.

On the configuration step of grvc-ual, I've only chosen the mavros backend. This combination used to work in Ubuntu 18.04, but might be playing a role in noetic.

Any pointers as to what I may be missing? I'm not sure how @McKayCyborg solved their issue in #699

@argenos PX4 is continuously tested in CI and Ubuntu 20.04 is the best supported system. All the SITL testing is run through gazebo11 / Ubuntu 20.04

Therefore, I would say your errors are related to the project grvc-ual using, which I have no knowledge of

I'm seeing the same error as in #419 it seems. And I just noticed this could be a duplicate of #850, but I can see the iris.world file locally.

@argenos It means you are using an outdated version of PX4. Iris.world doesnt exist anymore: https://github.com/PX4/PX4-SITL_gazebo/tree/master/worlds

@Jaeyoung-Lim Hmmm, no one did cleanup. What is the current default world? http://docs.px4.io/main/en/sim_gazebo_classic/#improving-distance-sensor-performance

Are the other iris worlds around, like the hitl_iris.world mentioned in text, and the copter itself, which is mentioned in multiple places? http://docs.px4.io/main/en/sim_gazebo_classic/multi_vehicle_simulation_gazebo.html#video-multiple-multicopter-iris
