It means that the model is no triangle strip. If it were, it would be compiled to a more optimized format. Then again, i've never seen a model in real life that is a triangle strip. You can build them in code for some very special cases, but it's usually not worth it anyway. You can simply ignore this message.
That there is no compiled-message is an indicator that your shader never gets compiled. One reason might be because you haven't compiled the mesh itself. Or it's not visible. Or the shader isn't assigned any longer to it at render time.
