Very Important How to compile after editing aodv files ?

In cd ns-2.35 folder

     i) ./configure  ( optional )

     ii) make clean

     iii) make

    iv) make install or  sudo make install

Possible Error

when i do step ii ..when it completes this error come :
g++ -Wl,-export-dynamic -o common/ptypes2tcl common/ptypes2tcl.o
./common/ptypes2tcl > gen/ptypes.cc
/bin/sh: 1: cannot create gen/ptypes.cc: Permission denied
make: *** [gen/ptypes.cc] Error 2

 I am assuming, you have solved the error as  mentioned. (FYI - login as root then do all the compilation if you have denied of permission)
