It's literally three steps, assuming you have the equivalent of the debian "build-essential" dependencies installed on your system for cmake, compiler. It's the exact three rows of my post, pasted one at a time into the CLI. The llama-server build guide page is actually pretty good.
I mean, sure, if there's people who can't figure that out, they're probably better off using a GUI that is a wrapper on top of somebody else's precompiled llama-server, like unsloth studio or lm studio. There's a good sized market for that and I wish them well.
You're right about all of that up until the point any one of those commands doesn't work and you get a garglblargl amount of incomprehensible error messages. You've been in the sauce for so long that you've forgotten what it's like to start fresh in these things.
