different multicast woes
Running either ns 2.1b3 or a recent snapshot on this:
My simple multicast simulation script (okay, on top of a fairly
complex mesh topology) happily parses all the
construct-a-simple-multicast-tree Tcl (liberally copied from
tcl/ex/newmcast/cmcast-100.tcl, too...) without error; it's after
that the fun begins.
I'd appreciate it if someone could at least provide
some debugging tips, as what this implies and how to rectify it is a
little beyond me at present:
ns: _o4446 start:
(_o4446 cmd line 1)
invoked from within
"_o4446 cmd start"
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 "_o4446" line 2)
(SplitObject unknown line 2)
invoked from within
"_o4446 start"
rerunning and stepping through with tcl-debug active says:
1: $ns at 1.0 "$n(5) join-group $m0 $group"
dbg1.2> n
1: $ns at 7.0 "finish"
dbg1.3> n
1: $ns run
dbg1.4> n
total = 132
5: _o4 run-mcast
dbg5.5> n
5: _o4446 start
dbg5.6> n
5: tkerror {ns: _o4446 start}
dbg5.7> n
ns: _o4446 start:
(_o4446 cmd line 1)
invoked from within
"_o4446 cmd start"
invoked from within
"if [catch "$self cmd $args" ret] {
set cls [$self info class]
global errorInfo
set savedInfo $errorInfo
error "error when calling class $cls: $args" $..."
(procedure "_o4446" line 2)
(SplitObject unknown line 2)
invoked from within
"_o4446 start"
A tkerror? It's always in SplitObject, too.
I'm stumped. Suggestions?
thanks,
L.
