Hello, Go in the following directory
ns-allinone-2.29/ns-2.29/sctp and open the file named "sctp.h". Go to line number 705 in that file and delete "SctpAgent::" from that line. Via terminal go to ns-allinone-2.29/ns-2.29 and give the following commands: ./configure make clean make make install Hope it helps. Regards, Mohit P. Tahiliani
