Dear Sir I am using ns-2.31 under cygwin and I have been trying to extend it with the leach extension developed for ns-2.27. after following the procedure specified in the pfd document that comes with it I got the following error: trace/trace.cc: In static member function `static int Trace::get_seqno(Packet*)' : trace/trace.cc:206: error: `PT_XCP' undeclared (first use this function) trace/trace.cc:206: error: (Each undeclared identifier is reported only once for each function it appears in.) trace/trace.cc: In member function `virtual void DequeTrace::recv(Packet*, Handl er*)': trace/trace.cc:567: warning: int format, nsaddr_t arg (arg 5) trace/trace.cc:567: warning: int format, nsaddr_t arg (arg 6) trace/trace.cc:586: warning: int format, nsaddr_t arg (arg 5) trace/trace.cc:586: warning: int format, nsaddr_t arg (arg 6) make: *** [trace/trace.o] Error 1 I do not know what is wrong, and I wonder if I have to install ns-2.27, but I tried to install it but it did not work. I am grateful for your help Regards Anas
