2017-10-26 编了一段fftw的程序，报错说有无法解析的外部符号 impfftwmalloc，这个要怎么办啊，按照网上的方法生成了三个lib文件，也添加到链接器里了，还是没有变化，一样报错，请教高手帮忙解.
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..
I could create it with the architecture : x86_64.a and i386.a.
Fftw Library Machine
I am using Mac OS X 10.9.2 , SDK 7.1, and gcc 49
i was working on the script from : http://stackoverflow.com/a/23279575/3553742
- 2019-11-14 In response to one of the comments, it can make sense to build fftw yourself because there are many different choices to make when you build fftw depending on your hardware. Most likely you have AVX2 available on your machine, which was less common on Macs in 2014 when that blog was written. You probably also have multiple cores.
- 2016-9-15 fftw在mac下参照官网很容易配置，但是windows下出现了问题。首先，从fftw官网下载相应的运维 前段时间用到了傅里叶变换，就从网上下载了一些傅里叶的代码，例如FFT842等等不同基频的程序，但是可移植性较差，不能满足个人要求。.
- 2014-6-4 I am using Mac OS X 10.9.2, SDK 7.1, and gcc 49. I was working on the script from. Now I need the Fftw library. On my PC its working ( i could install it through macport,: sudo port install fftw-3 +universal) with the architectur x8664.a and i386.a.But now I.
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?
Mount Aloysius Library
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?
