I imported this recommended project into OMNeT++ to find out how to combine 80211p and LTE communication in my simulation.
It's recommended to use Veins 5.0-alpha2, OMNeT++ 5.5.1, INET 3.6.5, SimuLTE 1.0.1 for this project.
But I'm using Veins 5.0, OMNeT++ 5.6.2, INET 3.6.6, SimuLTE 1.1.0.
When I import that project into the environment I have configured, the path problem occurs as shown in the following image.
I changed the Car.ned code of veins_hetvnet as follows.
// Original
import lte.stack.phy.ILteNic;
// Modify
import lte.stack.ILteNic;
After making this change, the import error is resolved, but the lteNic submodule d2dCapable variable error occurs.
Do I have to configure the same environment to run this project?
Unfortunately I don't understand how to fix the code.

Above my problem is resolved. Using
SimuLTE 1.1.0, I was unable to fix the error by modifying the code. Therefore, I usedgit resetcommand.First, cloning repository to your machine.
Second, reset commit from cloned repository.
That's it!
You can now use
SimuLTE 1.0.1and you can use theveins_hetvnetproject normally.
