Re: DDD 3.3.12 (i386-apple-darwin20.1.0) gets Xt error

[William Oquendo]

Hi, I was never able to make ddd run on my mac. And even running gdb is difficult, with the code signing and so on. Apple is really pushing lldb. When I need to use ddd and its plotting capabilities, I use a linux virtual machine. Sorry for not giving a solution. Just wanted to share my experience with you.

Greetings!

I'm brushing off my assembly language skills by building a Forth
interpreter from scratch on my Mac (V. 11.6).  The commands to build the
executable are:

nasm -g -f macho64 -o forth.o forth.asm
ld -macosx_version_min 11.0.0
-L/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib -lSystem
-o forth forth.o

After a few days with lldb (which runs very nicely on that executable) I
decided to give ddd a try.  I ran "brew install ddd" and that ran
cleanly. Then when I tried to debug my NASM assembly language program
with "ddd forth" (and also just "ddd"), I got this:

======
$ddd forth

"ddd --manual" actually worked but I couldn't figure out how to navigate
it (I haven't used GNU's info format in a couple of decades--sorry).
