Introduction to FFTW
FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions. The name, "FFTW," stands for "Fastest Fourier Transform in the West." FFTW was developed at MIT, which is in the east.
Non-Multilib
Compile the package:
./configure --prefix=/usr --enable-shared && make
There are several options that can be passed to the configure script to optimize the resulting build. Execute ./configure --help to see these additional options.
Install the package:
make install
Multilib
32Bit
Compile the package:
CC="gcc ${BUILD32} -fPIC" CXX="g++ ${BUILD32} -fPIC" \
./configure --prefix=/usr --enable-shared &&
make
There are several options that can be passed to the configure script to optimize the resulting build. Execute ./configure --help to see these additional options.
Install the package:
make install
N32
Compile the package:
CC="gcc ${BUILDN32} -fPIC" CXX="g++ ${BUILDN32} -fPIC" \
./configure --prefix=/usr --libdir=/usr/lib32 --enable-shared &&
make
There are several options that can be passed to the configure script to optimize the resulting build. Execute ./configure --help to see these additional options.
Install the package
make install
64Bit
Compile the package:
CC="gcc ${BUILD64} -fPIC" CXX="g++ ${BUILD64} -fPIC" \
./configure --prefix=/usr --libdir=/usr/lib64 --enable-shared &&
make
There are several options that can be passed to the configure script to optimize the resulting build. Execute ./configure --help to see these additional options.

Short Description
- fftw-wisdom: Creates wisdom (pre-planned/optimized transforms) for specified sizes, writing wisdom to stdout or file.
- fftw-wisdom-to-conf: Converts wisdom (stdin) to C configuration routine (stdout).
