Gazebo failure

[rdesc]

Hi, I can't get gazebo to launch correctly.

I get the following error:
libGL error: MESA-LOADER: failed to retrieve device information

I'm on Ubuntu 20.04 and Nvidia driver version 510.

That's an error but searching for it suggests that it should be more of a warning than an error: https://forums.raspberrypi.com/viewtopic.php?t=193902

There's not enough information to reproduce your problem in this. As this seems to be more of a request for help on usage versus a bug report. Please ask on answers.ros.org with a full description of your system, the fully command line options that you're using as well as the whole console output of your run so we can try to see what the underlying error is.

Thanks, I managed to resolve the issue via exporting some variables:

# for future use - to support multiple Gazebo versions
export GZ_VERSION=garden

# not usually required as should default to localhost address
export GZ_IP=127.0.0.1

# ensure gazebo finds the config for this installation
export GZ_CONFIG_PATH=\
$HOME/gz_ws/install/share/ignition

# ensure the model and world files are found
export GZ_SIM_RESOURCE_PATH=\
$HOME/gz_ws/src/asv_wave_sim/gz-marine-models/models:\
$HOME/gz_ws/src/asv_wave_sim/gz-marine-models/world_models:\
$HOME/gz_ws/src/asv_wave_sim/gz-marine-models/worlds
