Re: [ns] ns-2 and trace files

[Andrea Josi <mr_josi@yahoo.it>]

Hi,

i am encountering similar problems: actually i get
segmentation fault when i run tcl/ex/tg.tcl, where
"example-trace" is used (i am using ns-2.1b8);
this is the error that is dumped:

-------------------------------------------------

warning: no class variable Tracefile::debug_

        see tcl-object.tcl in tclcl for info about
this warning.

warning: no class variable Tracefile::debug_

        see tcl-object.tcl in tclcl for info about
this warning.

could not stat example-trace
Segmentation fault (core dumped)    

----------------------------------------------------

What is the right way to use "example-trace" then ?

Thanks very much.
