Error while building ns-3

Hi Everyone

While building the ns-3 code, i am getting the following error. Please help me to resolve this. Let me know if any additional information is required. 

Code is downloaded from the following link https://github.com/bestephe/ns-3-tcpbolt

Hi,

I’m here to kick ass and chew bubblegum and I’m all out of bubblegum.
Fortunately for you, I'm not going to direct my rage to you. Plus, I promised to be not be too much aggressive, so I'll go buy some bubblegums.

[20 minutes later, with some bubblegums]

The git site states "The modified ns-3-dev code used in TCP-Bolt (Infocom 2014)". Great... somebody working on an up-to-date ns-3 release.

WRONG. It's a ns-3-dev somewhere in between 3.16 and 3.17, and it doesn't compile on my machines.

I hate when people turn me down... [grab another bubblegum].

I wish I could be ore precise, but without a building system I can't.

The error is from the linker. The "PriorityTag" class is in a module not being linked with another module, apparently the "internet" one.

src/internet/wscript, line 95

    obj = bld.create_ns3_module('internet', ['bridge', 'mpi', 'network', 'core'])

must be

    obj = bld.create_ns3_module('internet', ['bridge', 'mpi', 'network', 'core', 'dcn'])

... and this dependancy makes me chew a LOT of bubblegums.

BTW, more stuff similar to this may come up. The solution is always similar.

Hope this will help you fix the issues.
