Hello,

Why do I have errors, where something "is an inaccessible base of `
    MyGenerator'"??

It happens when I am loading Generator to the kernel.

orocos/include/control_kernel/NextGenKernel.hpp: In member function `bool
    ORO_ControlKernel::detail::BaseKernel<CPort, SPort, IPort, MPort, OPort,
    _Extension>::addGenerator(_Generator*) [with _Generator = 
MyGenerator, CPort
    = ORO_ControlKernel::detail::DataObjectLockedC, SPort =
    ORO_ControlKernel::detail::DataObjectC, IPort =
    ORO_ControlKernel::detail::DataObjectC, MPort =
    ORO_ControlKernel::detail::DataObjectC, OPort =
    ORO_ControlKernel::detail::DataObjectC, _Extension =
    ORO_ControlKernel::KernelBaseFunction]':
