How would I compile Kiss_fft to use the double data type C++?

I am looking to compile KISS_FFT (Keep it simple stupid) so that it can accept an array of double as input and output an array of doubles.

KISS_FFT is a library which does a fast Fourier Transformation on a set of data and outputs the result. By default it looks like it uses the float data type.

You just need to define the makefile variable DATATYPE, e.g.:

make DATATYPE=double ...

This in turn defines the macro kiss_fft_scalar as double.

To see this in action:

cd test
make DATATYPE=double test
