Hi everyone. I'm trying to set up a retro battle station emulation machine on my old Mac mini (to save it from the trashbin since it's a Core 2 duo and I wouldn't make much use of it anyway hdhshahah) and since I've always been interested in the Dec PDP line (and the first years of the hacker culture) I was extremely happy to find a complete build for ITS on GitHub: https://github.com/PDP-10/its

But when I tried to compile it (on my linux system first) it gave me this error:

Kernel: 6.15.7-1-MANJARO gcc (GCC) 15.2.1 20250813 When trying to build with simh:

Same exact error when I tried to compile it on a server of mine, with these specs: Kernel: 6.8.0-71-generic gcc: Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0

I really have no idea what it could be. I hope I'm not asking a stupid question, but I haven't found any solutions anywhere. I obviously have all the other dependencies in place.
