Error pertaining to 'lib_coacd.so' plugin

[HarshithaBR]

Hi Team,
After the setup of the repository, while running the python test_scene.py results in the following error in the Unity Console.

Mono path[0] = '/home/harshitha07/Documents/phyrc/RCareWorld/pyrcareworld/pyrcareworld/demo/executable/Player/Player_Data/Managed'
Mono config path = '/home/harshitha07/Documents/phyrc/RCareWorld/pyrcareworld/pyrcareworld/demo/executable/Player/Player_Data/MonoBleedingEdge/etc'
Preloaded '[libOni.so](http://liboni.so/)'
Preloaded 'lib_burst_generated.so'
Preloaded '[libassimp.so](http://libassimp.so/)'
Preloaded 'libgrpc_csharp_ext.so'
Preloaded '[liblibvhacd.so](http://liblibvhacd.so/)'
Unable to preload the following plugins:
lib_coacd.so

I have tried installing missing dependencies, and libgomp1, but still facing the above issue.

I would be helpful, if anyone can suggest a fix.

Thanks and regards

Hi @HarshithaBR could you double check if lib_coacd is in this path?

Thank you for your reply!
I have checked, to confirm that lib_coacd is in the mentioned path

Hi @HarshithaBR

Please use the following command to check if all necessary dependencies are installed. If not, please install them:

ldd /home/harshitha07/Documents/phyrc/RCareWorld/pyrcareworld/pyrcareworld/demo/executable/Player/Player_Data/Plugins/lib_coacd.so

Also, make sure the file has the proper access permissions:

chmod 755 /home/harshitha07/Documents/phyrc/RCareWorld/pyrcareworld/pyrcareworld/demo/executable/Player/Player_Data/Plugins/lib_coacd.so

If there are still errors, please send them over.

I have run the above command. There are no unresolved dependencies.

the error that is persistent is as follows

Are you using a Ubuntu or WSL?

Resolved by installing libc6-dev, and changing the permissions for libdl.so
