Re: [Discuss-gnuradio] package 'gnuradio-fft' not found

You are missing quite a few libs.  The one that's causing your specific issue:

-- Configuring gr-fec support...
--   Dependency ENABLE_VOLK = ON
--   Dependency Boost_FOUND = 1
--   Dependency ENABLE_GNURADIO_RUNTIME = ON
--   Dependency ENABLE_GR_BLOCKS = ON
--   Enabling gr-fec support.
--   Override with -DENABLE_GR_FEC=ON/OFF
-- checking for module 'fftw3f >= 3.0'
--   package 'fftw3f >= 3.0' not found
-- Could NOT find FFTW3F (missing:  FFTW3F_LIBRARIES FFTW3F_INCLUDE_DIRS) 
-- 
-- Configuring gr-fft support...
--   Dependency ENABLE_VOLK = ON
--   Dependency Boost_FOUND = 1
--   Dependency ENABLE_GNURADIO_RUNTIME = ON
--   Dependency ENABLE_GR_BLOCKS = ON
--   Dependency FFTW3F_FOUND = FALSE
--   Disabling gr-fft support.
--   Override with -DENABLE_GR_FFT=ON/OFF

Notice that fftwf3 is missing which means you don't have libfftw which means no FFT support.  Since you're running Ubuntu you should look at https://wiki.gnuradio.org/index.php/UbuntuInstall and run the canned apt-get commands for your version.

yes cmake of gnuradio has gr-fft and many other components disables. Following is the outcome of cmake
