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.
