'*****' has not been declared

[Beckmann, Niklas]

Dear members of the gnuradio mailing list,

since 2 days I am trying to fix this error. So maybe one of you guys can help me...

I am grateful for any help.

I have the following code, which is the impl.h file of a block from my oot module.

#ifndef INCLUDED_FLORIANINETS_BASEBAND_DEROTATION2_IMPL_H
#define INCLUDED_FLORIANINETS_BASEBAND_DEROTATION2_IMPL_H

#include <gnuradio/FlorianiNets/baseband_derotation2.h>

namespace gr {
namespace FlorianiNets {

class baseband_derotation2_impl : public baseband_derotation2
{
private:
    float f_mu;
    float f_error;
    gr::digital::constellation_sptr;
    gr::digital::c_constellation;
    float wrap_phase(float phi);

public:
    baseband_derotation2_impl(float mu,
                              gr::digital::constellation_sptr,
                              gr::digital::constellation);
    ~baseband_derotation2_impl();

    // Where all the action really happens
    int work(int noutput_items,
             gr_vector_const_void_star& input_items,
             gr_vector_void_star& output_items);
};

} // namespace FlorianiNets
} // namespace gr

#endif /* INCLUDED_FLORIANINETS_BASEBAND_DEROTATION2_IMPL_H */

When I run make, I get this error list, and I simply don't know why:

I tried everything, what I know to fix this, but I did not manage to do so.

Maybe someone else has a good advice.

Thank you very much,

Nik
