[ns] Multi-interface support howto, Ramon Submission

[Nguyen Lan]

Hi Ramon and all,

After following the document when I recompile ns I got this error. Maybe 
I was wrong some where

aodv/aodv.o:/usr/local/ns/mulf/ns-allinone-2.27/tclcl-1.15/tclcl.h:60: 
multiple definition of `nIfaces'
aodv/aodv_logs.o:./common/packet.h:413: first defined here
aodv/aodv.o:./aodv/aodv_packet.h:161: multiple definition of `targetlist'
aodv/aodv_logs.o:./common/packet.h:353: first defined here
aodv/aodv.o:aodv/aodv.cc:65: multiple definition of `ifqueuelist'
aodv/aodv_logs.o:./common/packet.h:423: first defined here
collect2: ld returned 1 exit status
make: *** [ns] Error 1

Could anyone help me.

Thanks
