[ns] Can anyone tell me how to debug ns2 2.33 using gdb? No successful examples could have been googled yet.

[matt Wood]

Dear friends,
  I've read the ns-doc chap24 and chap28, and followed the
instructions (Q3) found in http://web.syr.edu/~dchen02/FAQ.txt,  but
when I try to debug using '$gdb ns' it says: no debugging symbols
found.

 Same questions can be found in the mail-list but they still
remain unresolved. Please tell me if this  2.33-allinone can be
debugged by gdb. And if it is not, what debugging method can I use  if
I want to add a new MAC protocol?

 Thank you in advance.

Yours sincerely,
Matthew Wood

Hello Matt,

A while ago I followed the steps in that FAQ to enable the debugging in ns2
and it worked fine with me. I used gdb to debug my C++ code as follows:
gdb ns
run my_tcl_script.tcl

My code used to give me segmentation fault and I used gdb to find out where
the problem was.
I debug my Tcl code using "puts" to print on the output what is happening. I
know it is not much efficient but till now it was sufficient.

Best regards,

To debug I suggest you use Eclipse and gdb;

You must open the entire simulator in a project in eclipse.

details are in here:
http://nsnam.isi.edu/nsnam/index.php/Developer_Information#Development_with_Eclipse

Turn on symbols generation in the Makefile (don't forget this or you
will receive a no symbols error).

use

CCOPT = -g

To debug oTCL code, I recommend Pedro Estrela's site. You'll find all
about oTCL debugging.

Hi,
 I think the problem is duet to the dynamic loadable libraries which
ns2.33 uses. When I use 'dll-symbols' command in gdb and set breakpoints it
says:
warning:
can not insert breakpoint
Error accessing memory address 0x100ae1a0: Input/Output error.

 Could you mail me the steps in which you successfully debugging
your program? After using 'dll-symbols' command to load the libns.dll, I an
use 'list' command to show the source files, but, unfortunately, setting
breakpoints still does not work.

Bests,
Matt

Hello Walled,
  I installed a Ubuntu and tried those steps again. It works. Thank you
very much.
