I am adding additional option in a GRC block. Its Soft Frame Equalizer
As you see in the figure, the block has options for Algorithm, Frequency, Bandwidth, Log
and Debug. I added my own variable "Scaling".
For this, first I edited in soft_frame_equalizer_impl.cc as follows :
soft_frame_equalizer::sptr
soft_frame_equalizer::make(Equalizer_soft algo, double freq, double bw, int
scaling, bool log, bool debug) {
return gnuradio::get_initial_sptr
(new soft_frame_equalizer_impl(algo, freq, bw, scaling, log, debug));
}
soft_frame_equalizer_impl::soft_frame_equalizer_impl(Equalizer_soft algo,
double freq, double bw, int scaling, bool log, bool debug) :
gr::block("soft_frame_equalizer",
gr::io_signature::make(1, 1, 64 * sizeof(gr_complex)),
gr::io_signature::make2(2, 2, 48, 48 * sizeof(float))),
d_current_symbol(0), d_log(log), d_debug(debug), d_equalizer(NULL),
d_freq(freq), d_bw(bw), d_scaling(scaling), d_frame_bytes(0),
d_frame_symbols(0),
d_freq_offset_from_synclong(0.0)
void
soft_frame_equalizer_impl::set_scaling(int scaling) {
d_scaling = scaling;
}
And then in soft_frame_equalizer_impl.h as follows :
public:
soft_frame_equalizer_impl(Equalizer_soft algo, double freq, double bw, int
scaling, bool log, bool debug);
~soft_frame_equalizer_impl();
void set_algorithm(Equalizer_soft algo);
void set_bandwidth(double bw);
void set_frequency(double freq);
void set_scaling(int scaling);
private:
int d_scaling;
And then in soft_frame_equalizer.h from the include directory as follows :
public:
typedef boost::shared_ptr<soft_frame_equalizer> sptr;
static sptr make(Equalizer_soft algo, double freq, double bw, int scaling,
bool log, bool debug);
virtual void set_algorithm(Equalizer_soft algo) = 0;
virtual void set_bandwidth(double bw) = 0;
virtual void set_frequency(double freq) = 0;
virtual void set_scaling(int scaling) = 0;
And finally in the xml file as follows :
<param>
<name>Scaling</name>
<key>scaling</key>
<value>0</value>
<type>real</type>
</param>
It compiles well, but when I execute the program, it throws following error:
sender started

line 644, in make
return _ieee802_11_swig.soft_frame_equalizer_make(*args, **kwargs)
TypeError: Required argument 'debug' (pos 6) not found
What I am missing ? Where else I need to edit ?
