Urgent !!!Please HELP !!!!! HI ALL, I’m in very deep shit guys !! I tried to apply this patch http://snad.ncsl.nist.gov/proj/iptel/ns2-sip-simulation/ns-2.1b9a.sip.patch to my ns-allinone-2.26 in order to implement SIP protocol In this version.This project is critical for me because it’s the project of my diploma!!!!! I tried to apply this patch located here with the command “patch -p0 < ns-allinone-2.1b9a.sip.patch” in the terminal but the cursor stop and I got nothing I waited for hours, the PC didn’t execute anything and the hard drive is not working!! But the PC didn’t block!!! And I could easily return to the command line [EMAIL PROTECTED] just typing ctrl+c. So I tried to do this MANUALLY and I followed the instructions: -first I modified the MAKEFILE.in by adding the line sip.o\sip_server.o\sip_tg.o\ -Second I modified the files agent.cc agent.h and packet.h as the tutorial do. -I modified ns-default.tcl and ns-packet.tcl located on /root/Desktop/ns-allinone-2.26/ns-2.6/tcl/lib -I create the files sip.h;sip.cc;sip_server.cc;sip_server.h;sip_tg.h;sip_tg.cc -I typed ./configure -I typed make on the ns-2.26 directory And the PROBLEMS began!! The files .o was correctly generated and putted in the directory /ns-2.26/sip because the .CC and .h files were putted there,BUT I got the message invalid reference to ‘vtable SIPAGENT’ and other error which told me that my new agent SIPAGENT that I created is not referenced by my vtable!! I thought that this was the cause of the virtual functions but all my functions were correct and well defined and declared!! I ignored the message and I tried to test my implementation by the tcl files located on the same patch file like proxy_test.tcl for exemple I got the error which told me that the command “set sipA [new Agent/SIP jwjung www.nist.gov] “ is invalid and that NS is enable to create or “locate” my new agent “Agent/SIP” what the problem!!!!!!!!!!!!!!!!!!!!!!!!! PLEASE I’m spending sleepless nights in this problem I loosed 10 KG of my weight and I’m really really sick!!!! PLEASE HELP ME HELP ME HELP ME!!! THANKS
