Re: Help getting started debugging Emacs on macOS Sierra

[Itai Berli]

Thanks, Tino.

I've finally managed to get gdb to work by executing the following two instructions at the gdb command prompt:

(gdb) cd ~/emacs

(gdb) file src/bootstrap-emacs

However, your suggestion to execute the following from the terminal, didn't work:

> emacs ~/emacs/src

Is there a way to configure gdb to use the above settings (cd and file) automatically?

That means, gdb doesn't know which program to debug.

Here's the complete contents of the *gud* buffer.

Current directory is ~/
No symbol table is loaded.  Use the "file" command.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 1 (main) pending.
(gdb) r
Starting program:  
No executable file specified.
Use the "file" or "exec-file" command.

Assuming your executable is at:
~/emacs/src/bootstrap-emacs
you can do in the gdb command line:
file ~/emacs/src/bootstrap-emacs

However, the Emacs source code is in ~/emacs. Maybe this is the problem? But I started Emacs from ~/emacs. How can I set
the *gud* buffer's current directory?

DUNNO why it doesn't starts at ~/emacs.
You can try from a terminal:
|> emacs ~/emacs/src
;; now call gdb
M-x gdb RET ; it should offer to debug 'bootstrap-emacs'
