hi, I'm sorry about the manual. as u said, I
configured my ns2 again with the --enable-debug option
along with the --with-tcldebug=./../ option. it's
reconfiguring fine and then I'm making it. it's
compiling fine. after that I tried with the same
xample by adding a statement, "debug 1" ,in the first
line of the script, just to check whether it's getting
enabled or not. so when I tried to run the script in
the normal way(not in the debugging mode) like ns
example.tcl at the prompt, it's giving a warning
stating that

warning: Script debugging disabled. Reconfigure with
--with-tcldebug, and recompile. 

this is wat I xactly did, but even then it's giving
this warning. why? but the script is running fine. is
it a prob with Makefile? or shud I set the library
path of tcl-debug libraries in .cshrc file? or is
there something else that I shud do. thanx for ur
support.
