I'm trying to run a simulation with DCE using the ShadowingLoss propagation model and because of that, I tried to configure the Buildings module but the linker keeps returning the following error:
$ ./waf --run myexample

The ns-3 tests executed succefully for buildings.
I read the tutorial and model library, searched a lot for this problem, but could not find a solution. The closer I came was this thread from october: [https://groups.google.com/forum/#!topic/ns-3-users/jfHnK2G3fN8].
One other thing I did but still didn't work was add 'buildings' on the wscript. When I did that, I got this error:

I also would apreciate some help on how to use the shadowing propagation loss model, because I didn't find any example showing how to configure that. I'm trying to set it just like the other models, but it's not working:
wifiChannel.AddPropagationLoss ("ns3::BuildingsPropagationLossModel::ShadowingLoss");
Best regards!
