(ERROR) Class not found -- perhapts its code was not linked in, or the class wasn't registered with Register_Class() or define_Module()

Hi, I’m working on a project where I’m trying to track the power consumption of some bulbs and implement an optimization algorithm for them.

However, I’ve run into an error:

Basically, I wanted to create a library where I can define a getter and setter for PowerConsumption.
I initially tried to use AlternatingEpEnergyConsumer, but I realized it doesn’t implement the required functions. I then attempted to extend the class and add the functions myself, but I couldn’t get the INET library to compile with the new .o files.

So I decided to create a new class called CustomEnergyConsumer in my own project.

Everything compiles fine and the project builds successfully. However, when I open the OMNeT++ GUI and load the simulation, I get the error shown in the first screenshot above.

Here’s what I’ve done:

1. I used Define_Module(romanescupark::power::consumer::CustomEnergyConsumer); in my .cc file.
2. The module is correctly linked in the project — as you can see with:
   nm out/clang-release/RomanescuPark.exe | grep CustomEnergyConsumer

Do you have any ideas on how I can fix this issue? I can provide more details if needed.

Also, if anyone has a working example where they’ve successfully extended an INET 4.5 class or created a custom one, I’d really appreciate it if you could share some code or tips.

Thanks in advance!

The easier is to include your source code model directly in inet-framework tree.
If you don't want this, you need to review the configuration of your project, probably, the directly is not included in the build options

Do you have any ideas on how to compile the INET framework properly? When I try to compile it, the entire library doesn't seem to compile. In the output clang-release folder after compilation, only the .dll files appear, and there's no src folder with all the .o files.

I suppose that you are using windows and omnet 6.1.
Usually you will have a directory out/
and inside you should have clang-release and clang-debug. You should have inside the share library and the src directory with the objects files.
When you build the inet-framework, check the output in the console. The build trace is there.
