[Discuss-gnuradio] USING SET/GET_GAIN UHD USRP FUNCTION

[Simone Ciccia S210664]

hi,

I have some problem to use USRP UHD set/get_gain functions.

In my code, _impl.cc I have included:

#include <gnuradio/uhd/usrp_source.h>

the header file in which 

virtual double get_gain() and virtual void set_gain()

are defined!

When I try to compile errors appear:

error: ‘get_gain’ was not declared in this scope
     DB_gain =(float*) get_gain(0);  

error: ‘set_gain’ was not declared in this scope
    set_gain(g_z,0);  

Have I forgot some definitions for these functions?

Thanks
Simone
