Dear all I am using ns 2.34 on red hat linux. All the wireless simulation codes on AODV or existing protocols are working fine. But when I am adding new protocol, I am able to make the simulator after running ./configure >> make clean >> make. But during execution of tcl file with new protocol code I am getting following errors. I have carefully implemented code step by step by thoroughly reading ns material on internet and ebooks. I shall be highly thankful to you.
