Problem with generated Code C++

[user346]

Hey,
I modeled a simple state machine in Enterprise Architect. Afterwards I generated a c++ code to test this statemachine in a simulation.
After trying to run a simulation, I got some errors. In the generated codes are type names, that aren't defined anywhere. (These are for example type names like ContextManager*, StateData*, String..).
How can I fix this problem?
Is there a standard library for Enterprise Architect, which I have to include?
Or is there another option to fix this?

Thanks for your help.

I'll link a picture, where you can see the problem.
