Imported NED type not found: 'org.car2x.veins.subprojects.veins_inet.VeinsInetManager'

[Tiago Silva]

Hello!
I'm new with SimuLTE and sorry if this is the wrong place to ask for help. I'm trying to install Veins-LTE following this tutorial: http://simulte.com/add_veins.html. However, when the projects are imported by Omnet++ **the example simulation cars** are presenting this error in: https://github.com/inet-framework/simulte/blob/9b1d71360f5c8034e038e30620500289722c0c52/simulations/cars/Highway.ned#L25
Due this, I can't run this simulation. As indicated by tutorial, I'm using:
- OMNeT++ v5.1.1;
- INET-Framework v3.6 (included in complete package tar.gz from tutorial) ;
- SUMO v0.30.0 .

I tried to install this using Windows and Linux VM. The same behaviour occurs.

Thanks in advance!

Hello Tiago, 

I used to have encountered the same problem. The following is the solution:

Import the project using: File | Import | General | Existing projects into Workspace. Then select the Veins directory and check the "Search for nested projects" box. This will add both "veins" and "veins_inet" projects. Click Finish. [1]

Hello, Jia!

Thank you! This step solve the problem. However, when I build the veins_inet project it presents some include errors... I fix this problem in files:

simulte_veins/veins-veins-4.6/subprojects/veins_inet/src/veins_inet/VeinsInetManager.cc
From:
#include "veins_inet/VeinsInetManager.h"
#include "veins/base/utils/Coord.h"
#include "veins_inet/VeinsInetMobility.h"
To:
#include "VeinsInetManager.h"
#include "veins/base/utils/Coord.h"
#include "VeinsInetMobility.h"

simulte_veins/veins-veins-4.6/subprojects/veins_inet/src/veins_inet/VeinsInetMobility.cc

From:
#include "veins_inet/VeinsInetMobility.h"
To:
#include "VeinsInetMobility.h"

With this, the compilation problem was solved. However, when I run the cars simulation the following error occur:

terminate called after throwing an instance of 'omnetpp::cRuntimeError'
  what():  ASSERT: Condition '(int)signalListenerCount.size() == lastSignalID+1' does not hold in function 'registerSignal' at ccomponent.cc:414

Simulation terminated with exit code: 134

I verified the additional steps of http://simulte.com/add_veins.html and it's correct in the project:

"Import the project using: File | Import | General | Existing projects into Workspace. Then select the Veins directory and check the "Search for nested projects" box. This will add both "veins" and "veins_inet" projects. Click Finish.

Right-click on the "simulte" folder | Properties | Project References. Then tick the "veins_inet" box. Click OK."

Did you have this problem too?

Thanks in advance!

Hi Tiago,

I am new to omnet++ and veins. I faced the same errors as you did when building the veins_inet project. I tried to fix it VeinsInetManager.cc and VeinsInetMobility.cc in the same way as you, by removing the additional directory 'veins_inet' from the path of VeinsInetManager.h and VeinsInetMobility.h.
After this change, I am able to build the project successfully however the Car simulation still gives error code 139. 
Were you able to resolve your issue? 
It seems to me that the fix of removing 'veins_inet' in VeinsInetManager.cc and VeinsInetMobility.cc isn't the right way to go about it. 
Any pointers to resolve my problem would be appreciated.

Below is the console log when Car Simulation is run on omnet++ IDE :

For some reason, your simulation is not configured to be based on the Veins project. This is why you saw missing include paths (during compilation) and this is why you are now seeing missing symbols (during linking): The symbol that is missing can be found in libveins, but your opp_run call only loads three libraries, as can be seen from the three "-l" switches (-l .../lte -l .../veins_inet -l .../INET) passed to opp_run. You might have misconfigured which projects depend on which or you might have changed which compiler and linker switches are exported/imported from the various projects in your workspace.

Maybe adding not just veins_lte, but also the Veins project as a "project reference" to your SimuLTE can serve as a crude workaround, but something is seriously wrong in your project configuration.

If setting up SimuLTE+Veins continues to give you trouble, you might also want to switch to using "Instant Veins", a virtual machine that already has all projects set up and configured correctly. This virtual machine exists in two versions: with and without SimuLTE. Make sure to download <https://veins.car2x.org/download/> the one with LTE support.

Best,

Christoph
