Error Compiling on 32bit Parabola Linux with gcc

Hello, I’ve recently started playing C:DDA again on the ncurses stable release, but I’d also like to compile from source too. Sadly, I’m getting an error, and I was wondering if someone would help diagnose it for me.
I’ve been using make like so:

which then ends at:

In file included from /usr/include/c++/6.3.1/string:52:0,
from mtype.h:6,
from game.h:4,
from item_factory.h:4,

make: *** [Makefile:194: obj/item_factory.o] Error 1
make: *** Waiting for unfinished jobs…

I can try to attach the full output of make if needed, but for some reason I can’t attach the 33.8kB file, or even use a pastebin link / code tags. Hopefully it’s just some kind of spam protection on new accounts or something and I can upload it later.
Regardless, I would be extremely grateful for the help!
