I try to run a simulation in ns3 and it shows me this problem.

[0/2] Re-checking globbed directories...
[2/2] Linking CXX executable /home/geo...scratch/ns3.41-v2x-highway-v40-default
msg="Attribute name=NrSpectrumPhyList does not exist for this object: tid=ns3::NrGnbPhy", +0.000000000s -1 file=/home/george/Downloads/ns-allinone-3.41/ns-3.41/src/core/model/object-base.cc, line=251
NS_FATAL, terminating

Command 'build/scratch/ns3.41-v2x-highway-v40-default' died with <Signals.SIGABRT: 6>.

Please help anyone who knows, what i should to do.

You just hit the bug I discovered a few days ago and I'm working on fixes for nr. Make sure you are using a compatible v2x model for your example.

The problem will probably look like the following.

- is bugged code that should be replaced
+ is fixed code

- Ptr<NrSpectrumPhy> nrSpectrumPhy;
- uePhyFirst->GetAttribute("NrSpectrumPhyList", ueSpectrumPhysFirstBwp);
- nrSpectrumPhy = ueSpectrumPhysFirstBwp.Get(0)->GetObject<NrSpectrumPhy>();
+ Ptr<NrSpectrumPhy> nrSpectrumPhy = uePhyFirst->GetSpectrumPhy();
