There is an open source project [Core Analyser](http://sourceforge.net/projects/core-analyzer/) that may have everything you need. – Preet Sangha May 16 '13 at 11:02

Why the python tags if this is C code? – symcbean May 16 '13 at 11:12

@symcbean, because gdb extension supports python. – Baijnath Jaiswal May 16 '13 at 11:38

What is "gdb extension"? Gdb supports lots of languages. – symcbean May 16 '13 at 12:11

@symcbean, means python script can be executed inside gdb promp,which make gdb very powerful – Baijnath Jaiswal May 16 '13 at 12:18

@PreetSangha, thanks but do you know how to do that under gdb? – Baijnath Jaiswal May 16 '13 at 13:43

@Baijnath: why must you use GDB if another open source tool can do it as well. – Lie Ryan May 17 '13 at 08:45

@Lie Ryan, Actually i want to write a script in python which will be executed under gdb to perform those operations. – Baijnath Jaiswal May 17 '13 at 14:20

is there any direct command to get all the global symbols name and value inside gdb? – Baijnath Jaiswal May 21 '13 at 06:17

There isn't a way to iterate over symbol tables from Python yet. So, it can't be done.
However, adding support to expose this information to Python would be a reasonable thing to do.

@Tromey , Thanks. So could you please guide me how to get all the global variables(excluding libraries symbols), data structures and sub-structures (with address, type and values) from core dump manually in gdb prompt .? so i will try to do this in python. – Baijnath Jaiswal May 24 '13 at 04:41

It can't be done programatically from the gdb CLI, either. You have to extend the C code. – Tom Tromey May 24 '13 at 16:46
