P3DFFT stands for Parallel Three-Dimensional Fast Fourier Transforms. It is a library for large-scale computer simulations on parallel platforms. It implements 3D FFT and related algorithms such as Chebyshev transform (an important class of algorithm for simulations in a wide range of fields). P3DFFT uses 2D, or pencil, decomposition.

I am trying to use p3dfft for discrete FFT of 3d functions. When I am executing the code used p3dfft.h it is giving me this error which asks for DEF_FFT_FLAGS. Any help will be appreciated! Thanks
