[ndnSIM] Unable to Use NDN Link Control Helper on the Annotated Topology [‘FailLink’ was not declared in this scope]

[Md Monjurul Karim]

Greetings Everyone,

*I am having following error while compiling*

[3118/3564] Compiling scratch/icn-test-1.cc
../scratch/icn-test-1.cc: In function ‘int ns3::main(int, char**)’:
../scratch/icn-test-1.cc:105:41: error: ‘FailLink’ was not declared in this
scope
    Simulator::Schedule (Seconds (10.0), FailLink, consumer1, router1 );


*My Annotated Topology (partial) looks like this:*
# node  comment     yPos    xPos
C1        NA          1       1
R1        NA          1       2
R2        NA          2       2
P1        NA          1       3

# srcNode   dstNode     bandwidth   metric  delay   queue
# bandwidth: link bandwidth
# metric: routing metric
# delay:  link delay
# queue:  MaxPackets for transmission queue on the link (both directions)
C1       R1     10Mbps     1    10ms     10
P1       R1     10Mbps     1    10ms     10
R2       C1     10Mbps     1    10ms     10
R2       R1     10Mbps     1    10ms     10
R2       P1     10Mbps     1    10ms     10

 #include "ns3/ndnSIM-module.h"
