veins_gym error

[JeffreyRed]

After setting up the project to use veinsgym. I am getting the bellow error. Do you know what could be the issue? I have checked and everything looks ok. the Define_Module is there, the makefile, I am using CUSTOM the one provided in the folder. I see the obj are ok.

I used OMNet++ 5.6, and 5.7 same error.

A runtime error occurred:

Class "GymConnection" 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 (omnetpp::cModule) SerpentineScenario2 (id=1), during network setup

Launch a debugger with the following command?
