|
<p>This chapter describes the installation and customization of FFTW, the
|
|
latest version of which may be downloaded from
|
|
<a href="http://www.fftw.org">the FFTW home page</a>.
|
|
</p>
|
|
<p>In principle, FFTW should work on any system with an ANSI C compiler
|
|
(<code>gcc</code> is fine). However, planner time is drastically reduced if
|
|
FFTW can exploit a hardware cycle counter; FFTW comes with cycle-counter
|
|
support for all modern general-purpose CPUs, but you may need to add a
|
|
couple of lines of code if your compiler is not yet supported
|
|
(see <a href="Cycle-Counters.html">Cycle Counters</a>). (On Unix, there will be a warning at the end
|
|
of the <code>configure</code> output if no cycle counter is found.)

</p>
|
|
|
|
<p>Installation of FFTW is simplest if you have a Unix or a GNU system,
|
|
such as GNU/Linux, and we describe this case in the first section below,
|
|
including the use of special configuration options to e.g. install
|
|
different precisions or exploit optimizations for particular
|
|
architectures (e.g. SIMD). Compilation on non-Unix systems is a more
|
|
manual process, but we outline the procedure in the second section. It
|
|
is also likely that pre-compiled binaries will be available for popular
|
|
systems.
|
|
</p>
|
|
<p>Finally, we describe how you can customize FFTW for particular needs by
|
|
generating <em>codelets</em> for fast transforms of sizes not supported
|
|
efficiently by the standard FFTW distribution.
