【问题描述】：
我正在尝试安装 FFTW，当我到达 ./configure --enable-mpi --enable-type-prefix --enable-float 命令并运行它时，这是我得到的错误。我该如何克服呢？如果有帮助，我会在 Windows 10 上使用 Cygwin。

【问题讨论】：
-
fftw3 包已经在 Cygwin 中可用。为什么需要 mpi 版本？
-
一般来说，构建 Cygwin 包的通常做法是在
autoreconf之前运行configure。如果您查看fftw3的 Cygwin 源包，当前的 Cygwin 包就是以这种方式构建的。 -
嗨，我正在按照说明使用 Cygwin 运行 Gadget2 代码。我无法克服错误。
-
Gadget2 似乎已老化。它来自 2005 年，需要 fftw 版本 2。在自己的网站上
FFTW 2.1.5 is the stable release of FFTW2, last updated in 1999. FFTW 2.1.5 is obsolete, but because its API is incompatible with that of version 3.x, we continue to distribute it for those users who require backwards compatibility. -
我尝试使用该版本，但仍然卡在该错误上:(
