Linux 正在安装fftw--无法猜测生成类型

我正在尝试安装FFTW，当我进入./configure-enable mpi-enable type prefix-enable float命令并运行它时，我得到的是错误。我如何克服这个问题？如果有帮助的话，我在Windows10上使用Cygwin

fftw-2.1.5太旧了，需要建议在最近的Cygwin下正确配置

$ ./configure --enable-mpi --enable-type-prefix --enable-float  --build=x86_64-pc-cygwin

checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
....

我不会打赌你会使用MPI和HDF5进行干净的运行，因为它们也比在Gadget2上测试的要新

fftw3软件包已经在Cygwin中提供。为什么需要mpi版本？一般来说，在配置之前构建Cygwin包以运行autoreconf是一种常见做法。如果您查看fftw3的Cygwin源程序包，那么当前的Cygwin包就是以这种方式构建的。您好，我将按照说明使用Cygwin运行Gadget2代码。我无法克服这个错误。小工具2似乎过时了。它是从2005年开始的，需要fftw版本2。FFTW2.1.5是FFTW2的稳定版本，上一次更新是在1999年。FFTW2.1.5已经过时，但由于其API与3.x版不兼容，我们继续为需要向后兼容的用户分发它。我尝试使用该版本，但仍然遇到了该错误：

$ ./configure --enable-mpi --enable-type-prefix --enable-float  --build=x86_64-pc-cygwin

checking whether build environment is sane... yes
checking for gawk... gawk
