2017-3-21 据说FFTW(Fastest Fourier Transform in the West)是世界上最快的FFT。 为了详细了解FFTW以及为编程方便,特将用户手册看了一下,并结合手册制作了以下FFTW中文参考。 其中大部分是原文重点内容的翻译,并加入了一些注解。. 2003-11-26 Installation and Customization. This chapter describes the installation and customization of FFTW, the latest version of which may be downloaded from the FFTW home page. As distributed, FFTW makes very few assumptions about your system. All you need is an ANSI C compiler (gcc is fine, although vendor-provided compilers often produce faster code).
I am trying to create the fftw library with the architectures: armv7.a and arm64.a and I am sticking hier from two weeks ago.

Here, it is assumed that the reader is already familiar with the usage of the uniprocessor FFTW routines, described elsewhere in this manual. We only describe what one has to change in order to use the multi-threaded routines.
I could create it with the architecture : x86_64.a and i386.a.
I am using Mac OS X 10.9.2 , SDK 7.1, and gcc 49
Mcminnville Library Website
i was working on the script from : http://stackoverflow.com/a/23279575/3553742
But I am getting all the libraries of architecture x86_64. Thats why I cannot lipo them. ( libfftw3f_armv7.a, libfftw3f_x86_64.a, libfftw3f_arm64.a, libfftw3f_i386.a)
So any idea how to update this script to get the correct architecture? Access hidden user library files mac os 10.9 download.
P.s. by
: I am getting the error :
configure: error: Need a version of gcc with -mfpu=neon
So I just delete --enable-neon and it works. Is it a mistake?

Thanks a lot.
