Package Mismatch Errors When Running Simu5G on Ubuntu

[sajjad6464]

Hi, I'm trying to run Simu5G on Ubuntu 20.04 but keep encountering package mismatch errors like Declared package 'simu5g.simulations.NR.networks' does not match expected package '' in file MultiCell_Standalone.ned and Declared package 'simu5g.simulations.NR.cars' does not match expected package 'cars' in file Highway.ned. I'm using OMNeT++ 6.0.3, Simu5G 1.2.0, and INET 4.5.0. I’ve corrected the network name in omnetpp.ini, moved extra omnetpp.ini files to a configs folder, verified the package line in NED files, moved Highway.ned to a cars directory, updated ned-path in omnetpp.ini and the ./run script to ../../src;/home/sajjad/inet/src;./networks;./cars, cleared the OMNeT++ cache, and set environment variables, but the errors persist. Can you help me resolve this issue?

Hi! I'm having a similar issue when running the simulation cars in the OMNeT++ IDE. I'm using Ubuntu 24.04, OMNeT++ 6.1.0, INET 4.5.4, Veins 5.3.1, and Simu5G 1.3.0.

It says that the Network simu5g.simulations.NR.cars.Highway is not found, but it is located in the same folder. I've also tried creating another ned and Network to try and reference to, bit it still won't work. What should be done to resolve this issue? Thank you!

I appreciate your response to my GitHub issue—thank you for taking the time to help. As I continue working with Simu5G, I have a few more questions that I’d love to ask during my simulation process.

Hi @sajjad6464 and @jhsison ,

This issue occurs because the cars package is excluded in the OMNeT++ NED Source Folders configuration. When the package is excluded, OMNeT++ cannot see highway.ned or other related files under simu5g/simulations/nr/cars.

Here’s what the exclusion looks like in the NED Source Folders dialog:

To fix this, simply re-enable the Simu5G “cars” feature in the OMNeT++ Project Features configuration. This will automatically remove the exclusion and make the package visible again:

You should also make sure that Veins is correctly installed and referenced in your workspace, since the Highway.ned example depends on it for mobility support.

Once Veins is up and running, you should be able to launch the Highway.ned example successfully.

P.S. I’m not currently working on this project, but the issue seemed straightforward, so I thought I’d give it a small push in the right direction. 😊
