How to attach some gdb variant within emacs?

How to attach some gdb variant within emacs?

[Max]

Hi all,

I need to use one variant of gdb for debugging. I thought it could be
attached into my emacs(latest cvs version) with the setting of the
variable
gud-gdb-command-name(with --fullname or --annotate=3). However, it
does not work. The command for gdb has no response at all. I tried it
on the older emacs(21.3) and there is no problem in this hack. Could
someone tell how to solve this?

Thanks a lot,

Max

Forgot to say, the version of this kind of gdb is 6.1.

Is this too old?

Thanks a lot.

The gdb window is shown within emacs. However, the gdb commands, e.g.
pwd, quit, have no response and freeze there. Sorry for the confusion.

Is it possible that this is caused by the init of old version gdb(6.1
with --annotate=1or3)? Because I saw sometimes the status bar shows
"initializing".

Thanks a lot,

The "--annotate=3" should work with M-x gdb in CVS Emacs.  You don't say what
platform you are using and 6.1 is quite an old version of GDB.  Try a newer
version if you can.  Otherwise do M-x gdb-enable-debug, start GDB in Emacs and
then when it freezes post the value of gdb-dubug-log here (or just to me if
it's too long).  Please do this with M-x report-emacs-bug so I can see your
configuration too.

The "--fullname" option with M-x gdb has been broken for sometime in
CVS Emacs and will go shortly.  Use M-x gud-gdb instead.

Hi Nick,

The gud-gdb works. That's really awesome. Thank you very much.

About the debug log, it has nothing but the license info even if I
input pwd or quit. I guess the root reason is that the gdb is too old.

Thanks and regards,

Max

It's just the old mode from Emacs 21.  The GDB grahical interface that uses
the "--annotate=3" option is much better.

I don't understand how the license info can be in the value of gdb-debug-log
as output is only logged after it's been printed

It's value (using `C-h v') should end something like this:

 (recv . "\n\x1a\x1apre-prompt\n(gdb) \n\x1a\x1aprompt\n")
 (recv . "\n\x1a\x1apost-prompt\n")
 (send-item "set width 0\n" ignore)
 (recv . "\n\x1a\x1apre-prompt\n(gdb) \n\x1a\x1aprompt\n")
 (recv . "\n\x1a\x1apost-prompt\n")
 (send-item "set height 0\n" ignore)
 (recv . "\n\x1a\x1apre-prompt\n(gdb) \n\x1a\x1aprompt\n")
 (recv . "\n\x1a\x1apost-prompt\n&\"\\n\\032\\032error-begin\\n\"\n&\"No registers.\\n\"\n~\"\\n\"\n~\"\\032\\032error\\n\"\n^error,msg=\"No registers.\"\n(gdb) \n")
 (send-item "server interpreter mi -stack-info-frame\n" gdb-get-version))

That may be the reason.  It should work on GNU/Linux but you don't say what
OS you are using
