Hi, I made some changes to my code and did a "make clean" and "make" and "make install".
After that, I couldn't run ns any more. The error messages says: ---------------------------------------------------- ns wireless.tcl ns: [code omitted because of length] : invalid command name "Node/DelayBox" while executing "Node/DelayBox instproc init args { eval $self next $args $self instvar db_classifier_ set db_classifier_ [new Classifier/DelayBox] $self insert-entr..." invoked from within "if {[ns-hasSTL] == 1} { Simulator instproc set-nix-routing { } { Simulator set nix-routing 1 Node enable-module "Nix" } -------------------------- This problem still won't go away even after I reinstalled ns2.31. Does anyone know what happened? Does it have anything to do with me updating my Ubuntu system? Thanks a lot! Jiang Wu
