I would recommend specifying your operating system.

The compiler needs to be executable. You should look up how to make a file executable for your linux distro.
I tried on: ubuntu 18.04, ubuntu 16.04 and debian 10. I gave permission to execute file. Compiler file should add himself after installing oxide?
Are your plugins loading despite the error?
No, they are not.
The error means you are running an older version of Oxide for Hurtworld. You'll need to update for the plugin compiler to download.
