Can't import NED files to use channels OMNeT++

Question

I'm not able to import channel types from one .ned file to another in OMNet++.

I have A.ned where I define a channel called Ether.

channel Ether extends ned.DatarateChannel
    {
        datarate = 10bps;
        delay = 10ms;
        ber = 1e-10;
    }

I want to then use that channel in B.ned without having to repeat the definition. I've tried:

import A;

module B extends A
{
    ...  
}

Both files are in the same package. A.ned contains a network and not a compound module but I tried making it a module and adding the @isNetwork tag and that did not work. The error is "Cannot resolve channel type Ether" when I use it as such:

router.port[i] <--> Ether <--> switch[i].port[0];

I feel like this should be easy but I haven't been able to find much help online or in the Simulation Manual. Any help is greatly appreciated!

Maybe you could help us by providing the whole ned files? For example with included package definition? — Ventu
I can but my question is more general. I'm basically just asking how to import channel types so that I don't have to keep creating the same channels in every module that I make. I just tried to provide an example. — Triton

You need to link the project that includes the A.ned to the project that includes B.ned using the project references.
