Re: GNU Radio 3.9 OOT derived class

[Alvaro Pendas Recondo]

Hi Vasil,

Thank you for your answer. Should not be Gnuradio "3.9" instead of "3.9"?. Anyway, I tried with both options and I got the same error:

Target "TFMv3_python" links to target "gnuradio::gnuradio-digital" but the
  target was not found.  Perhaps a find_package() call is missing for an
  IMPORTED target, or an ALIAS target is missing?

What I changed was:

1 - Write find_package(Gnuradio "3.9" REQUIRED COMPONENTS digital filter blocks analog fft) in CMakeLists.txt

2 - Write target_link_libraries(gnuradio-TFMv3 gnuradio::gnuradio-runtime gnuradio::gnuradio-digital

gnuradio::gnuradio-blocks gnuradio::gnuradio-filter gnuradio::gnuradio-analog gnuradio::gnuradio-fft) in lib/CMakeLists.txt

As I've said, I tried with both "3.8" and "3.9" with the same output. I had to add filter blocks analog and fft as expected based on the explanation

The GR_REQUIRED_COMPONENTS is no longer used in GNU Radio 3.8 and 3.9. You need to add "digital" in the Gnuradio's find_package list and then link your OOT module with gnuradio::gnuradio-digital. It should be something similar to:

    find_package(Gnuradio "3.8" REQUIRED COMPONENTS digital)
    target_link_libraries(gnuradio-TFMv3 gnuradio::gnuradio-digital)

See https://wiki.gnuradio.org/index.php/GNU_Radio_3.8_OOT_Module_Porting_Guide#GNU_Radio_Components
