Hello all.... I really need help in the following problem as I have been stuck in this for a while: 1- I am trying to do a simulation in ns 2.28 as cluster based replica application (where I modified the ping files), but an error happens to me as following after I implement the new ping.cc and ping.h inside the ns2 ns: _o401 send0: (_o401 cmd line 1) invoked from within "_o401 cmd send0" invoked from within "catch "$self cmd $args" ret" invoked from within "if [catch "$self cmd $args" ret] { set cls [$self info class] global errorInfo set savedInfo $errorInfo error "error when calling class $cls: $args" $..." (procedure "_o401" line 2) (SplitObject unknown line 2) invoked from within "_o401 send0"
2- even if I try to run the ping.tcl file in the tutorial example , the same error happens, so would you please tell me what this error means and how to solve it . I really need this help so badly * the ping and the tcl files are attached
