[ns] I NEED HELP IN ORDER TO DEBUG C++ CODE

[Edwin Cruz]

hi everyone

In past message I read that in order to debug I need to do:
++
look for the line :

# Build Tcl8.3.2  (should be around line 173)

In this section you need to add the option --enable-symbols to the line :
./configure --enable-gcc --disable-shared --prefix=$CUR_PATH || 

so it becomes:
./configure --enable-gcc --enable-symbols --disable-shared
--prefix=$CUR_PATH || 

Now, still in the ns-allinone/install file, look for the tclcl section.

# Build tclcl  (should be around line 260)

in this section, you need to add --enable-debug to your configure line, such
that:

./configure ||  ...

becomes

./configure --enable-debug || ...

ok, we're done with this one. save and close.

now, go into your ns-allinone/ns directory, and open your Makefile.in. Search
for CFLAGS (should be around line 90), and change it from

CFLAGS  = $(CCOPT) $(DEFINE)

to

CFLAGS  = -g $(CCOPT) $(DEFINE)

++
 I did this steps but now my scripts don´t work, what Happend
I use Ns-2-29. I read the section in the ns manual for debug but is not
clear.
If some one know a good guide, and could send me it. I aprecite the help.
