FFTW is a free collection of fast C routines for computing the
|
||
|
|
Discrete Fourier Transform in one or more dimensions. It includes
|
||
|
|
complex, real, symmetric, and parallel transforms, and can handle
|
||
|
|
arbitrary array sizes efficiently. FFTW is typically faster than
|
||
|
|
other publically-available FFT implementations, and is even
|
||
|
|
competitive with vendor-tuned libraries. (See our web page
|
||
|
|
http://fftw.org/ for extensive benchmarks.) To achieve this
|
||
|
|
performance, FFTW uses novel code-generation and runtime
|
||
|
|
self-optimization techniques (along with many other tricks).

||
|

The doc/ directory contains the manual in texinfo, PDF, info, and HTML
|
||
|
|
formats. Frequently asked questions and answers can be found in the
|
||
|
|
doc/FAQ/ directory in ASCII and HTML.

INSTALLATION
|
||
|
|
------------
|
||
|
|
|
||
|
|
INSTALLATION FROM AN OFFICIAL RELEASE:
|
||
|
|
|
||
|
|
Please read chapter 10 "Installation and Customization" of the manual.
|
||
|
|
In short:
|
||
|
|
|
||
|
|
./configure
|
||
|
|
make
|
||
|
|
make install
|
||
|
|
|
||
|
|
INSTALLATION FROM THE GIT REPOSITORY:
|
||
|
|
|
||
|
|
First, install these programs:
|
||
|
|
|
||
|
|
ocaml, ocamlbuild, autoconf, automake, indent, and libtool.
|
||
|
|
|
||
|
|
You also need the ocaml Num library, which was standard in Ocaml but
|
||
|
|
was removed without warning in OCaml 4.06.0 (3 Nov 2017). On Fedora
|
||
|
|
30, try installing the ocaml-num-devel package.
|
||
|
|
|
||
|
|
Then, execute
|
||
|
|
|
||
|
|
sh bootstrap.sh
|
||
|
|
make
|
||
|
|
|
||
|
|
The bootstrap.sh script runs configure directly, but if you need to
|
||
|
|
re-run configure, you must pass the --enable-maintainer-mode flag:
|
||
|
|
|
||
|
|
./configure --enable-maintainer-mode [OTHER CONFIGURE FLAGS]
|
||
|
|
|
||
|
|
Alternatively, you can run
|
||
|
|
|
||
|
|
sh mkdist.sh
|
||
|
|
|
||
|
|
which will run the entire bootstrapping process and generate
|
||
|
|
.tar.gz files similar to those for official releases.
|
||
