Here is a version of the RoT MUD source code, version 1.4 with OLC, that compiles for me on Ubuntu 22.04.3 LTS.
It seems MUD resources are growing very thin these days. I’d like to remedy that if possible. If my brain doesn’t find something else to fixate on for a while.
I’ve included a README file in the main folder that outlines the couple of minor changes I made.
