SqliteOutputManager (code problem) and NS_UNUSED

[George]

Hello,

I am trying to write a scenario for the NR-U module. First, I made a CMakeLists.txt for the example folder and managed to compile it. 

Then the wifi-setup.cc has some codding issue for an unrecognised use of "AddDevice" which I fixed (or I think i fixed) by doing the following changes using "SpectrumWifiPhy" : 

 Ptr<SpectrumWifiPhy> wifiSpectrumPhy;

ObjectVectorValue WifiSpectrumPhys;

// wifiSpectrumPhy->SetAntenna (antennaArray);

for (uint32_t i = 0; i < m_gnbDev.GetN (); ++i)

{

Ptr<WifiNetDevice> netDevice = DynamicCast<WifiNetDevice> (m_gnbDev.Get (i));

wifiSpectrumPhy = WifiSpectrumPhys.Get (0)->GetObject <SpectrumWifiPhy> ();

wifiSpectrumPhy->SetAntenna (PointerValue (antennaArray));

}

// registering STAs devices to 3GPP model

for (uint32_t i = 0; i < m_ueDev.GetN (); ++i)

{

Ptr<WifiNetDevice> netDevice = DynamicCast<WifiNetDevice> (m_ueDev.Get (i));

wifiSpectrumPhy = WifiSpectrumPhys.Get (0)->GetObject <SpectrumWifiPhy> ();

wifiSpectrumPhy->SetAntenna ( PointerValue (antennaArray));

}

}

I am not sure if the wifi-setup.cc issue is fixed this way, I am new to c++ programming and ns-3 so I just follow other examples that work)

Now I still have the following errors regarding SQLmanager and NS_UNUSED:

NS_UNUSED error:

If anyone could give me some advice on how to solve this would be great, thank you!

Ok, I am not sure anymore if the NR-U module is usable at the moment because more and more errors from codes appear every time I fix the previous errors. Is anyone currently using the NR-U module?

[George]

Most of the errors come now from libns3.36.1-nr-u-default.so, with a set of undefined references such as: undefined reference to `ns3::WifiTxVector::~WifiTxVector()'
