Envmod usage about artery

[riebl]

The environment model is only enabled in the "envmod" configuration of the highway-police scenario, see

artery/scenarios/highway-police/omnetpp.ini

Lines 20 to 22 in a313146

	[Config envmod]
	network = artery.envmod.World
	*.traci.mapper.vehicleType = "artery.envmod.Car"

You should be able to run this configuration without modifications.

Side note: This scenario has been created for the chapter about Artery in a soon-to-be-published book "Recent Advances in Network Simulation".

Thanks for your reply!
Maybe I explained myself unclear: The highway-police scenario is running, and the option WITH_ENVMOD is enabled. Just I do not get where the environmental model is used at all, i.e., how I can use its information. Functions from PoliceServiceEnvmod are never called and it does not matter how the services-envmod.xml file looks like (I conclude from that, that it is not used at all).
If I change the PoliceService in services.xml to PoliceServiceEnvmod, then the initialization function is called, but no LocalEnvironmentModel can be found. As far as I understand, there is somewhere a mFacilities.register_const() needed, e.g., in src/artery/application/Middleware.cc, else the call in the initialization function of PoliceServiceEnvmod will fail...

artery.envmod.Car is an artery.inet.Car with an additional LocalEnvironmentModel. This model registers itself at the middleware's facilities, see LocalEnvironmentModel::initialize.
I have just run the envmod configuration of highway-police and PoliceServiceEnvmod is working as intended on my system. I have verified this by setting a breakpoint in gdb: break PoliceServiceEnvmod.cc:20 if objects.size() > 0

ok thank you, that seems now to be clear.

I tried it with gdb and even with terminal outputs, but both functions are never called. So my question:
What do you mean by running the "envmod configuration of highway-police"? Do I have to set an additional parameter? Probably I missed something there...
I have attached a screenshot of the running example. From my point of view, both local and global environment are not initialized (localEnvironmentModule and globalEnvironmentModule):

You are not using the envmod configuration. Please select "envmod" from the drop-down box in the dialog shown at OMNeT++ GUI's startup.

Many thanks @riebl for your fast support. Problem solved.
As I would like to work more with artery, is there a dedicated channel to discuss ongoing development, e.g., IRC?
