Adding a new DEN usecase - class not found

[ruipatcheco]

Hello,

With the help of your work, I can build some simple scenarios of my own. Thanks so much!!

Much similarly to #60 (comment)

My scenario:
A truck controlled by Storyboard will stop and send a DEN message, and vehicles receiving this message will stop or avoid the choosing the road where the truck is.

My work:
I added my DEN use case (IcyRoadUseCase) under artery/src/artery/application/den/ and modified mt-its2017 scenario to use my usecase (the reason I modified is because I don't know how to create a new one, I tried this: #49 but I wasn't successful) .

The problem and relevant test:
Whenever I run the altered mt-its2017, i get the following error:

Class "artery::den::IcyRoad" not found -- perhaps its code was not linked in, or
the class wasn't registered with Register_Class(), or in the case of modules and channels,
with Define_Module()/Define_Channel() -- in module (artery::DenService) World.node[0].middleware.DEN (id=85),
at t=0.1s, event 2

From my understanding, the error is saying that the module is not defined, but it is:

So it seems the Makefiles are not compiling my IcyRoadUseCase, because in src/artery/CMakeFiles/core.dir/application/den it only shows the other usecases.o

I am very grateful of the work you have done and am using it for my master's thesis. Thank you for your help :D

Additional information:

services.xml:
service type="artery.application.DenService" name="DEN">
listener port="2002" />

usecases.xml:
usecase type="artery.application.den.IcyRoad" />

Hi @ruipatcheco ,

please add your new source files to src/artery/CMakeLists.txt so they are compiled and linked into the final binary. In your particular case this would be a line "application/den/IcyRoadUseCase.cc" added to the add_library(core ...) target.
