@johnburkhard is that the only output you're seeing, or is it getting past the stage where it creates the "cmake-build-debug" directory? Are you running Linux?

Aha, try running make from the top directory, not from in the src directory.

If you run make install, it'll compile the binaries and put them in the install/bin dir (useful if you want to execute either using gdb). If you run make with no target, it'll start doorman & xania both up. At which point you'll be able to telnet to port 9000. And if you run make stop, it will shut them both down.
And if you did want to execute 'xania' using a debugger, due to a quirk of history, its current working directory must be the 'areas' directory when doing that (this is something the regular startup scripts take care of normally). We'll probably make that a bit easier at some point.

There's a bunch of other things that are not documented yet either, e.g. how to create/cobble together an Immortal character (any character level 92 to 100) for development or experimental purposes. We can look into adding some tips of that sort soon.

That ought to be fixed now (I hope!!) We're still in the process of making it work nicely with all the warning on. Please let us know: right now it's building on GCC 7.5.0 for production (old!) but I've had it building on my Ubuntu 20.04 recently.
We should update the CI to build on a few other compilers...I'll open an issue :)

Scratch that! Was able to repro with a release mode build on another machine! Thanks - will fix!
