connect openflow with ns3.28

[Hana Kuntová]

I try to connect openflow to ns3, according to this website https://www.nsnam.org/docs/release/3.28/models/html/openflow-switch.html

Everything is fine. After step ./waf configure --enable-examples --enable-tests --with-openflow=path/to/openflow

 it shows me 

"NS-3 OpenFlow Integration     : enabled"

But after command ./waf build

error like this shows up:

Build failed -> task in 'openflow-switch' failed (exit status 1): {task 140659035563152: cxxprogram openflow-switch.cc.1.o -> ns3.28-openflow-switch-debug}

Can anybody help me how to solve this problem?

Im using Ubuntu 16.04 and ns3.28
