How to compile this ns3 program

[sksdk]

I encountered the following error when compiling conga-simulation-large.cc

I encountered the following error when compiling conga-simulation-large.cc.
But I don't know what causes this program to fail to compile, I would like to ask what the problem is. Thanks you very much!

What GCC do you use? To compile this NS-3 Simulator, you can use gcc-4.9. We also provide a docker image. You can see README from our latest NS-3 repo: https://github.com/snowzjx/ns3-ecn-sharp .
