Hi Adanna,
ddd is an X11 application, and the message you reported typically indicates
that the X11 window system is not running and ddd can find no X11 display to
which it can connect. Have you installed the XQuartz server from
https://www.xquartz.org?
FYI, ddd is now a very old application and has not run well, if at all, on
macOS systems for the last two or three major releases due to problems with the
Xt library and the difficulties which gdb (ddd's underlying debugger) now has
with macOS executables. I have not used it successfully for years, if you can
figure out how please let me know! (I figured out how to use Xcode's debugger
in standalone mode as a substitute for ddd.)

Hi, I've installed ddd via terminal (i use vim) on my Mac laptop, but each time

try to run the code, I receive the following message:

I've tried installing LessTif and uninstalling openMotif to no avail. Is the
ddd window compatible with Mac OS devices? If so, how would I be able
to run it? My software is Mac OS 10.14.5 Mojave. Thanks in advance,
