error: 'sc_core::sc_object' is an inaccessible base of 'In_multiplexer<9, 4>'

Following is the complete error message:

Can anyone please help me understand this error message? I have no idea where to begin solving this.

Because of this line /classes/eeee720/systemc/systemc-2.3.3/include/sysc/utils/sc_vector.h: In member function 'sc_core::sc_object* sc_core::sc_vector<T>::object_cast(void*) const [with T = In_multiplexer<9, 4>]': 

I thinks it has do with the vector of type In_multiplexer.

I am using In_multiplexer as a single object and as a vector of objects. But it does not complain about the former.

Here is how  I declared them and used them:

N = 9, M =8

SINGLE OBJECT:

    In_multiplexer<N,M/2> AMux0{"AMux0"};

        AMux0.A(A);
        AMux0.B(B);
        AMux0.MODE(AMux0_SRC);
        AMux0.CORES(AMux0_sY);
        AMux0.SEL(AMux0_AIN_ADDR_part_select);
        AMux0.Y(pimcore0_A_part_select);

VECTOR OF OBJECTS:

    sc_vector<In_multiplexer<N,M/2>> AMux{"AMux", N-2};

        for (auto G = 1; G<N-1; ++G)
        {

            AMux[G].A(A);
            AMux[G].B(B);
            AMux[G].MODE(AMux_mode_vec[G]);
            AMux[G].CORES(AMux_core_vec[G]);
            AMux[G].SEL(AMux_sel_vec[G]);
            AMux[G].Y(part_sA[G]);

}

It is not about the vector, it is about your class hierarchy, esp. the inheritance of In_multiplexer. Using a search machine with 'c++ is an inaccessible base of' brings up e.g.  https://stackoverflow.com/questions/39332489/error-a-is-an-inaccessible-base-of-b.

I suspect when declaring In_multiplexer you forgot to publicly inherit from sc_module. So it should look like

template<unsigned X, unsigned Y>
class In_multiplexer : public sc_core::sc_module {
   
};

My suggestion is to revisit your C++ course material as this is basic C++

@Eyck Yes I missed the "public". I have it in all my other modules but missed it in this my bad. Thanks.
