emacs gdb layout

emacs gdb layout

[Ritchie]

After start gdb inside emacs with option "--annotation=3 --fullname",
I ran gdb-many-windows to get the gdb layout which contains the local
variable buffer, stack frame buffer and breakpoint buffers. However
these buffers do not show anything as I run debugger. In order to get
local buffer to display local variable values, stack frame buffer to
display stack status and break point display current breakpoint info
as I run the debugger, what am I missing?

Thank you in advance

The gdb option is "--annotate=3" so this wouldn't run at all.  Gdb should
start woth only one of these options and with M-x gdb it should be
"--annotate=3" for the graphical interface.  For text mode, i.e, like
Emacs 21, use M-x gud-gdb which will give you "--fullname".

I suggest uou read the debuggers section of the Emacs manual.

Sorry, that was a typo, what I had in my .emacs originally was
(setq gud-gdb-command-name "gdb --annotate=3 --fullname")
which I think is correct.

The version I'm using is Carbon Emacs  (emacs 22)

> I suggest uou read the debuggers section of the Emacs manual.

I read the manual, but it didn't work out very well. The manual says
"If gdb-many-windows is non-nil, then M-x gdb displays the following
frame layout "

but when I have the following lines in my .emacs:

(setq gdb-many-windows t)
(setq gdb-use-separate-io-buffer t)

and run M-x gdb, i still just get the simple layout. I have to bring
out the default
frame layout by giving another two M-x gdb-many-windows. The first one
is to
disable it, the second one is to enable it again, and then the frame
layout will
show up. So I just remove the (setq gdb-many-windows t) from .emacs,
and
run it manually everytime after I start gdb.

my problem is that in those buffers, locals, stack, breakpoints, there
is nothing
displayed as I run the program in gdb. In the manual, it just tells
you how to use
the buffer, e.g. click on a variable in local buffer to change the
value, but in mine,
it doesn't display any local variables, even if there is in the code.
Here is the screenshot:

http://cs655-1.ias.csusb.edu:8080/~zcai/layout.png

I'm not sure if it is normal but it would be nice if I could get it to
work like yours.

Did you give any commands for those buffers to display the contents?

And by the way, here is my configuration for gdb in my .emacs :

;; ===================================================================
;; Add color to the current GUD line (obrigado google)
;; ===================================================================

(defvar gud-overlay
  (let* ((ov (make-overlay (point-min) (point-min))))

    ov)
  "Overlay variable for GUD highlighting.")

(defadvice gud-display-line (after my-gud-highlight act)
           "Highlight current line."
           (let* ((ov gud-overlay)
                  (bf (gud-find-file true-file)))
             (save-excursion
                 (set-buffer bf)
                   (move-overlay ov (line-beginning-position) (line-
end-position)
                                   (current-buffer)))))

(defun gud-kill-buffer ()
  (if (eq major-mode 'gud-mode)
    (delete-overlay gud-overlay)))

(add-hook 'kill-buffer-hook 'gud-kill-buffer)

I don't understand how you reach that conclusion.  Generally you shouldn't need
to change the value of gud-gdb-command-name unless your executable has a
different name.  It should work for you if you leave it at it's original value
"gdb --annotate=3"

No, it won't if you use undocumented settings.

Try cleaning everything out.

(caveat, I use emacs 23 ut I'm fairly sure it worked in Emacs 22 like
this too).

I, using the code from here :

http://richardriley.net/default/projects/emacs/dotprogramming#sec-1.2

run gdb which then prompts (search for f12)

"gdb --annotate=3 progname"

And I get something like:

good luck!

--annotate=3  & --fullpath are _SORT_ of incompatible.
If you invoke GDB with both the options (i.e fullpath and annot =3)
the annotation level is _SILENTLY_ set to 1, you can check this by
trying "gdb> show annotation". With the annotation set to 1 (albeit
silently) your local,stack etc window cannot be displayed.My advice
would be try giving up the need to specify --fullpath along with
annotation=3, read up on GDB/M1 and experiment :)

Just do away with the need of specifying --fullpath and let
annotation=3 as is.

Where did fullpath come into it? Did I miss a post in the thread or did
you spot something elsewhere?

After start gdb inside emacs with option "--annotation=3 --fullname",


--fullname As in the first post .

Re: emacs gdb layout

[Ritchie]

Thanks guys. I kind of messed up. After removing "--fullname" option,
everything works like a charm.
