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".

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: "3-gdb-set". Try "help".
(gdb) Undefined command: "4-enable-pretty-printing". Try "help".
(gdb) Undefined command: "5-file-list-exec-source-files". Try "help".
(gdb) Undefined command: "6-file-list-exec-source-file". Try "help".
(gdb) Undefined command: "7-gdb-show". Try "help".
(gdb) Undefined command: "8-stack-info-frame". Try "help".
(gdb) Undefined command: "9-thread-info". Try "help".
(gdb) Undefined command: "10-break-list". Try "help".
(gdb) Undefined command: "11-thread-info". 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.
