I have installed NS2(2.29) and the ns2hcca patch from http://info.iet.unipi.it/~cng/ns2hcca/<http://info.iet.unipi.it/%7Ecng/ns2hcca/> The installation completed sucessfully, and I set the PATH, LD_LIBRARY_PATH, & TCL_LIBRARY variables as per the install message. However when I run the hcca example ( /ns-allinone-2.29/ns-2.29/tcl/ex/hcca/example.tcl ) , I get the following errors of which I can make out nothing. I am running the example in hcca directory only. I will be very grateful if somebody could help resolve this issue. A similar error was posted vide this link http://mailman.isi.edu/pipermail/ns-users/2006-August/057026.html ======== Error Msg ================ (_o4 cmd line 1) invoked from within "_o4 cmd run-identifier 1" 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" $..."
