‘class uhd::usrp::multi_u

GNU Radio
#1

I want to implement some functions in uhd::usrp::multi_usrp, and access
these functions from gnu_uhd_usrp_source. Therefore, I modify the files
as follows:

  1. multi_usrp.hpp
    I define the function
    virtual void enable_rx_fhop(const bool enb, size_t mboard = 0) = 0;

  2. multi_usrp.cpp
    void enable_rx_fhop(const bool enb, size_t mboard)
    {
    …
    }

    Then, I go to folder uhd/host/build/ and compile the files.
    Everything is fine, and no error appears.

  3. gr_uhd_usrp_source.h
    define:
    virtual void enable_rx_fhop_gr(const bool enb, size_t mboard = 0) =
    0;

  4. gr_uhd_usrp_source.cc
    void enable_rx_fhop_gr(const bool enb, size_t mboard)
    {
    _dev->enable_rx_fhop(enb, mboard);
    }

When I compile the files, I get the following error message:

gr_uhd_usrp_source.cc: In member function ‘virtual void
uhd_usrp_source_impl::enable_rx_fhop_gr(bool, size_t)’:
gr_uhd_usrp_source.cc:298: error: ‘class uhd::usrp::multi_usrp’ has no
member named ‘enable_rx_fhop’
make[5]: *** [gr_uhd_usrp_source.lo] Error 1

As I said, I compiled the UHD successfully, and cannot understand why
gr-source cannot find the functions. So, any suggestions? Thanks

Maybe its building against an old header. Did you install multi_usrp.hpp
to the include path?
