cannot find VehicleObstacleControl module -- in module (veins::PhyLayer80211p)

Question

I have encountered a critical issue in veins-5.2 simulation in the vehicle obstacle shadowing model as follows.

**initializeVehicleObstacleShadowing(): cannot find VehicleObstacleControl module -- in module (veins::PhyLayer80211p)
RSUExampleScenario.rsu[0].nic.phy80211p (id=11), during network initialization**

However, I can find VehicleObstacleControl module in the veins::PhyLayer80211p.cc as follows.

**unique_ptr<AnalogueModel> PhyLayer80211p::initializeVehicleObstacleShadowing(ParameterMap& params)
{
    // init with default value
    bool useTorus = world->useTorus();
    const Coord& playgroundSize = *(world->getPgs());
    ParameterMap::iterator it;
    VehicleObstacleControl* vehicleObstacleControlP = VehicleObstacleControlAccess().getIfExists();
    if (!vehicleObstacleControlP) throw cRuntimeError("initializeVehicleObstacleShadowing(): cannot find VehicleObstacleControl module");
    return make_unique<VehicleObstacleShadowing>(this, *vehicleObstacleControlP, useTorus, playgroundSize);
}**

I highly appreciate if you could provide me with some guidance so that I can resolve this problem.

Thank you in advance.

BR.

I have encountered the exactly same issue here. This error can be traced back to PhyLayer80211p.cc and VehicleObstacleControl.h within Veins, and further into OMNet++ files like csimulation.h and cmodule.h. It seems that the wanted scenario just could not find the path of vehicleObstacles (however, for the SimpleObstacleShadowing model, the scenario could find the path of obstacles), which is extremely confusing.

Solved already. In the OMNet++ world, just do not forget about those .ned files. Some modifications needs to be done in the scenario.ned file.
