Fix compilation error with recent ncurses versions
LINES/COLS is no longer a variable in ncurses, but is implemented as functions returning the resp values. Therefore they can not be assigned values anymore. Fix the code to use local variables instead. Also fix problems with ncursesw (addwstr) and add logic for font location in openSUSE.
Does not work for me:

Also as you can see the ./configure called some command badly
Can you please build against https://github.com/drmpjz/cmatrix once more? This should fix the issue during configure (there was an extra q at the end of a line, need to get a new keyboard, the escape key doesn't always work :-( )
Not sure this will fix the addwstr error for you. My fix addresses the ncurses/ncursesw case, while from the output above it looks like you don't have a ncurses at all. But maybe I am confused, you never know :-) Can you please try a man addwstr from a terminal? Does it return something at all? If so it should list the relevant include file in the synopsis. Can you post this here please?

In the future, will just make listings suffice?
The autoreconf issues are something you need to check on your end (you seem to be on a newer version of auto tools). Once we found a working link, please run autoupdate on your end to get rid of the warning (and I will check on my end if it still works with the older version of autotools. I'll check the missing symbols later. Still have a long run on my todo list for today :-)
I am not sure what you mean by autoreconf issues and a working link. It's my first time working with autotools. Ii'm on version 2.71.
I run autoupdate and here's what it changed:
$ diff configure.ac configure.ac.bak

I'll check the missing symbols later.
No problem and thank you!
Can you please try once more? And if you don't mind telling, what distro (and version) are you building on?
I am running Gentoo 2.15 on amd64 with the profile default/linux/amd64/23.0/split-usr/desktop
Ncurses is
sys-libs/ncurses-6.4_p20240414:0/6::gentoo USE="cxx gpm profile (split-usr) stack-realign (tinfo) verify-sig -ada -debug -doc -minimal -static-libs -test -trace" ABI_X86="(64) -32 (-x32)"
Here's the build log:
autoreconf -i
