I built a new version of GDB and it works properly from terminal. Now I want it to be executed when I run M-x gdb from emacs.

When you M-x gdb, Emacs will present you with a command-line in the minibuffer, like:
Run gdb (like this): gdb -i=mi something
You can edit this to supply a path to gdb, like:
~/my/install/bin/gdb -i=mi something

Yes I was able to run gdb but the problem is it does not integrate as the way the old gdb did. So i cannot see the breakpoint symbol being hit, navigate the source code by stepping, etc. Is there a way to do that, may be something in .emacs file– SujanKhJul 7, 2015 at 20:12

Note that you can customize
gud-gbd-command-nameto set the default command rather than changing the path every time. You do need to include the-i=miargument, though.– glucasJul 7, 2015 at 20:47 -
If it doesn't work with a new gdb, I would start by making sure that gdb is working ok; maybe running it with
-i=mito make sure MI mode is working -- just a smoke test. After that maybe I would make sure Emacs is using MI correctly. Maybe there's been some bug fixes or whatever. Jul 7, 2015 at 21:00 -
By using your answer I was able to run the new gdb in emacs but it did not allow me to navigate through the source file. It is just like running gdb in a terminal. For example with the default gdb in emacs, I can step through the source code visually.– SujanKhJul 7, 2015 at 22:03
