I have a simp cpuid.s assemblied to cpuid.o and linked to create a  
cpuid executable.

In emacs i do :

M-x gdb

and i give as argument the cpuid path.

I get :

Reading symbols from 
/home/chomwitt/Programming/Assembly/Blum/code/chap04/cpuid...done.
(gdb) Undefined command: "1-inferior-tty-set".  Try "help".
(gdb) Undefined command: "2-gdb-set".  Try "help".
(gdb) Undefined command: "3-gdb-set".  Try "help".

(gdb) Undefined command: "11-thread-info".  Try "help".
(gdb) Undefined command: "12-break-list".  Try "help"

(gdb)

What are those lines mean? Are those warnings or bugs?

M-x gdb gives you a default command `gdb -i=mi'. Make sure you don't
delete this `-i=mi' option, and just add a path to an executable:

  M-x gdb
  gdb -i=mi /path/to/cpuid

More about `-i=mi' option:

 gdb's mumble grumble      bellyache due to 'undefine command'  hint, do this 
──────────────────────────────────────────────────────────────────────────────
 (gdb) Undefined command:  "1-inferior-tty-set".                Try "help".   
 (gdb) Undefined command:  "2-gdb-set".                         Try "help".

 (gdb) Undefined command:  "12-break-list".                     Try "help"    
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

The gdb complains it has had undigestible 'undefined commands' on input feed?

And, suggests what to do about it by taiping 'help'.

Thanks.

That worked. Although i dont quite understand what is the /GDB/MI 
interface./

I  also enabled the option : GUD / GDB-MI / Display other windows

If i dont do that the other windows like breakpoints,registers etc wont 
close when i give the gdb> quit but i have to M-x kill-buffer each one.

GDB/MI is the so-called "machine interface". Back Then (TM), GDB was
just an interactive program: you type in things, GDB displays things
to you. With time, more-or-less graphical front ends appeared (among
them, of course, something written in Emacs). It became clear that
the interactive user interface wasn't the ideal way for a program to
control GDB, and thus MI was born.

Thanks.

So if i want to debug in emacs with gdb and have ide like functionality 
, giving me the ability to create breakpoint by clicking next to source 
lines or windows with updates on variables, registers , memory region 
etc then gdb must be able ta accept 'machine' like commands from the 
emacs gdb frontent.

Alexandros.

GDB/MI

|||I've learned about three ways to initiate a debugging session in  
emacs with gdb.|

||a.  M-x gud-gdb||

|Does option a. uses GDB/MI interface?|
