5. 5 5 Extending NS2 in OTcl If you don’t want to compile  Source your changes in your sim scripts Otherwise  Modifying code; recompile  Adding new files (ex. tcl/mysrc/msg.tcl) Change Makefile NS_TCL_LIB = \ tcl/mysrc/msg.tcl \ ….. Change tcl/lib/ns-lib.tcl Class Simulator source../mysrc/msg.tcl ….. Recompile

6. 6 6 Extending NS2 in C++ Modifying code  Make depend  Recompile Adding code in new files  Change Makefile (include “new files.o” in the object file list)  Make depend  Recompile
