[ns] how to use debugger
Hi, all!
I'd like to trace ns source code with a script (for example,
/foo/bar/ns/ns-2.1b6/tcl/lib/simple.tcl). I tried to trace with
debugger "gdb", but I couldn't. gdb is suspended like this:
------------------------------------------------------------------------
Current directory is /foo/bar/ns/ns-2.1b6/tcl/ex/
GNU gdb 4.18

(gdb) l
51 * Whatever the application does.

57 main(int argc, char **argv)
58 {
59 Tcl_Main(argc, argv,
60 Tcl_AppInit);
(gdb) b 59
Breakpoint 1 at 0x804aed6: file tclAppInit.cc, line 59.
(gdb) run
Starting program: /usr/local/ns/bin/ns
Breakpoint 1, main (argc=1, argv=0xbfbffa1c) at tclAppInit.cc:60
(gdb) s
0x8141940 in Tcl_Main () at gen/ptypes.cc:112
(gdb) s
%
---------------------------------------------------------------------
I located the line "debug 1" at appropriate place, but did not work well.
Because I couldn't understand the way of debugging only by reading
ns manual, please tell me the way in detail.
