Thanks, Paul. Do you use macOS? I read that Macs don't use gdb natively, but instead an alternative called LLVM. At any rate, gdb is not installed on my system. I can download and install it, but I'm a little hesitant, as I'm afraid it might clash with LLVM.

All the scripts finished successfully. In the end I was able to start the
Emacs GUI from the command line by running

open nextstep/Emacs.app

You've gotten up and running, so it sounds like all you need to do is to learn how to debug.

I normally use gdb under Emacs to debug Emacs. To do that, I run Emacs in the source directory, type the command "M-x gud-gdb RET bootstrap-emacs RET" to get GDB running on a subsidiary instance of Emacs, type the GDB command "b Fexpand_file_name" to plant a breakpoint in (say) Fexpand_file_name, and then type the GDB command "r" to run the Emacs being debugged.
