Try adding "gr::" before "fft::window" and make sure gnuradio/fft/window.h is 
included.

  #include <gnuradio/fft/window.h>

  lpfilter = gr::filter::firdes::low_pass(gain, sampling_freq, cutoff_freq, 
transition_bandwidth,
        gr::fft::window::win_type window = fft::window::win_type::WIN_HAMMING, 
beta = 6.76);

If this does not fix it then provide the exact error you are getting.
