Hi,
thank you for the answer.
I have created my own gnuradio block and linked the header that contains
set/get_gain function in the _impl.cc by means of (#include
<gnuradio/uhd/usrp_source.h>).
In the general work of _impl.cc I call directly these functions as
set/get_gain(), but the compiler returns errors!
Probably I'm forgetting to create the object that link this type of class
in my code _impl.cc

For example:

usrp_source.h looks like this

namespace gr {
namespace uhd {

class uhd_usrp_source;

class GR_UHD_API usrp_source : virtual public sync_block
{
public:
.................................

and in my code _imple.cc I have defined the object now:

usrp_source object;
object->set_gain();

Anyway, it does not work...
Do you know what I missing ? Probably this definition is wrong!

My best thanks for the help...
Simone
