Compilation 编译FFTW=configure时出错：错误：C编译器无法创建可执行文件

我正在尝试使用以下说明编译FFTW：

Download FFTW from http://www.fftw.org/download.html

Unzip and navigate to the appropriate folder.

In order to have a universal (32 + 64bit binary), you will build FFTW four 
separate times (twice for 32 vs. 64 and twice for float vs. double precision) 
and then combine the 32 and 64bit libraries into two fat/universal libraries.

In Terminal, type:
./configure CFLAGS="arch i686"
make
./configure --enable-float CFLAGS="arch i686"
make
mkdir .libs/32
cp libfftw3.a 32/libfftw3.a
cp libfftw3f.a 32/libfftw3f.a
./configure CFLAGS="arch x86_64"
make
./configure --enable-float CFLAGS="arch x86_64"
make
sudo make install
mkdir .libs/64
lipo -create .libs/32/libfftw3.a .libs/64/libfftw3.a -output libfftw3.a
lipo -create .libs/32/libfftw3f.a .libs/64/libfftw3f.a -output libfftw3f.a
cp libfftw3.a /usr/local/lib/libfftw3.a
cp libfftw3f.a /usr/local/lib/libfftw3f.a
To test if the created libraries at fat, type: lipo -info libraryname.a

但是，当我尝试键入第一个终端命令（./configure）时，会出现以下错误：

configure: error: C compiler cannot create executables

这是我第一次尝试编译任何东西，因此，如果有任何关于特定错误的帮助，或者仅仅是帮助我理解终端命令和编译的资源，我将不胜感激！我真的很想学这些东西，但我甚至不知道如何有效地学习！提前谢谢

以下是config.log：

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by fftw configure 3.3.3, which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ ./configure CFLAGS=arch i686

我不知道你从哪里得到你在问题中发布的文档，但它有一个打字错误。具体来说，

CFLAGS

变量在每个

/configure

行中都是错误的。他们应该是

./configure CFLAGS="-arch i686"
./configure --enable-float CFLAGS="-arch i686"
./configure --enable-float CFLAGS="-arch x86_64"

文档中缺少

-

，并导致

gcc

失败，因为它在第一次运行时无法分别理解选项

arch

和

i686

---

需要注意的是，如果您不需要FFTW的通用二进制文件，那么安装它的命令很简单

$ ./configure
$ make
$ sudo make install

您是否有

config.log

？这是Mac吗？是的，我用的是运行OSX 10.8.5的Macbook pro。我将使用config.log更新原始帖子
