[ndnSIM] problem with an underwater node while running, the NDN layer!

Hello ndnSIM team,

It seems that I should run a socket-based application, such as the
"ChronoSync", on UAN nodes.
I am following this link: https://github.com/spirosmastorakis/scenario-
ChronoSync

While running the "./waf", this error comes up!
Vostro1310:~/ndnSIM2.1/scenario-ChronoSync$ ./waf
Waf: Entering directory `/home/narguess/ndnSIM2.1/scenario-ChronoSync/build'
[13/13] Linking build/chronosync-simple
/usr/local/lib/libns3-dev-emu-optimized.so: undefined reference to
`ns3::LogComponent::LogComponent(std::string const&, ns3::LogLevel)'
collect2: error: ld returned 1 exit status

Regards,
Narges
