hi there!
i'm new on arduino, , i'm trying use fht library. installed library , when open fhb_adc example , verify it, says this:

fht_adc.pde: in function 'void loop()':
fht_adc:35: error: 'fht_input' not declared in scope
fht_adc:37: error: 'fht_window' not declared in scope
fht_adc:38: error: 'fht_reorder' not declared in scope
fht_adc:39: error: 'fht_run' not declared in scope
fht_adc:40: error: 'fht_mag_log' not declared in scope
