assert failed: Ipv4 AddressHelper

[chadni]

Hello,

I did install the Internet Stack in all the nodes but instead of that i m getting this error.

assert failed. cond="ipv4", msg="Ipv4AddressHelper::Assign(): NetDevice is associated with a node without IPv4 stack installed -> fail (maybe need to use InternetStackHelper?)", file=../src/internet/helper/ipv4-address-helper.cc, line=145

terminate called without an active exception

Command ['/home/Roshni/ns-allinone-3.20/ns-3.20/build/scratch/ourpaperFinal'] terminated with signal SIGABRT. Run it under a debugger to get more information (./waf --run <program> --command-template="gdb --args %s <args>"

Thank You

Chadni

Do NOT post the code in the message. There's a *@#§&%$ "attach a file" function and it hasn't been made just to have a fancy header in the posting interface.

Thank you very much,

Works for me. After adding the missing includes and a Simulator::Stop(Seconds(100)); of course.

What are all the directives we need to add?.because even after adding all the includes I am getting the same error
