I'm a master student beginner in simulations with omnet++. It's my first installation of omnet + veins + sumo for IVC simulations.

I follow the veins tutorial

I have omnet 5.5.1 sumo 1.3.1 veins 5.0 When I want to run veins examples I have this error:

 <!> Error: Cannot load library '../../src//libveins.dll': cant find！

End.

Simulation terminated with exit code: 1
Working directory: D:/omnetpp-5.5.1/samples/veins/examples/veins
Command line: ../../../../bin/opp_run.exe -m -n .;../../src/veins --image-path=../../images -l ../../src/veins omnetpp.ini

Thanks a lot for any answer.

  • Can you confirm that file it can’t seem to find is, indeed, there? If it is not: was building the simulation successful? If it was: could you try on another machine or in, e.g., the “Instant Veins” virtual machine? – Christoph Sommer Mar 22 '20 at 10:23
  • Thanks a lot.I can find libveins.dll file and the simulation was builded successfully.Then I install the omnet++ again.Ifirst run veins examples successfully,but the second time the same questins occurs. – Zhiheng Yuan Mar 29 '20 at 08:14
  • Did you change anything in-between the first run (which you say was successful) and the second run? Maybe you moved files somewhere else? – Christoph Sommer Mar 29 '20 at 08:17
  • No,i do the same things as the first run – Zhiheng Yuan Mar 29 '20 at 08:21
  • Did you try in Instant Veins? – Christoph Sommer Mar 29 '20 at 19:31
