Chris@42 80
Chris@42 81 <p>It should be relatively straightforward to compile FFTW even on non-Unix
Chris@42 82 systems lacking the niceties of a <code>configure</code> script. Basically,
Chris@42 83 you need to edit the <code>config.h</code> header (copy it from
Chris@42 84 <code>config.h.in</code>) to <code>#define</code> the various options and compiler
Chris@42 85 characteristics, and then compile all the &lsquo;<samp>.c</samp>&rsquo; files in the
Chris@42 86 relevant directories.
Chris@42 87 </p>
Chris@42 88 <p>The <code>config.h</code> header contains about 100 options to set, each one
Chris@42 89 initially an <code>#undef</code>, each documented with a comment, and most of
Chris@42 90 them fairly obvious. For most of the options, you should simply
Chris@42 91 <code>#define</code> them to <code>1</code> if they are applicable, although a few
Chris@42 92 options require a particular value (e.g. <code>SIZEOF_LONG_LONG</code> should
Chris@42 93 be defined to the size of the <code>long long</code> type, in bytes, or zero
Chris@42 94 if it is not supported). We will likely post some sample
Chris@42 95 <code>config.h</code> files for various operating systems and compilers for
Chris@42 96 you to use (at least as a starting point). Please let us know if you
Chris@42 97 have to hand-create a configuration file (and/or a pre-compiled binary)
Chris@42 98 that you want to share.
Chris@42 99 </p>
Chris@42 100 <p>To create the FFTW library, you will then need to compile all of the
Chris@42 101 &lsquo;<samp>.c</samp>&rsquo; files in the <code>kernel</code>, <code>dft</code>, <code>dft/scalar</code>,
Chris@42 102 <code>dft/scalar/codelets</code>, <code>rdft</code>, <code>rdft/scalar</code>,
Chris@42 103 <code>rdft/scalar/r2cf</code>, <code>rdft/scalar/r2cb</code>,
Chris@42 104 <code>rdft/scalar/r2r</code>, <code>reodft</code>, and <code>api</code> directories.
Chris@42 105 If you are compiling with SIMD support (e.g. you defined
Chris@42 106 <code>HAVE_SSE2</code> in <code>config.h</code>), then you also need to compile
Chris@42 107 the <code>.c</code> files in the <code>simd-support</code>,
Chris@42 108 <code>{dft,rdft}/simd</code>, <code>{dft,rdft}/simd/*</code> directories.
Chris@42 109 </p>
Chris@42 110 <p>Once these files are all compiled, link them into a library, or a shared
Chris@42 111 library, or directly into your program.
Chris@42 112 </p>
Chris@42 113 <p>To compile the FFTW test program, additionally compile the code in the
Chris@42 114 <code>libbench2/</code> directory, and link it into a library. Then compile
Chris@42 115 the code in the <code>tests/</code> directory and link it to the
Chris@42 116 <code>libbench2</code> and FFTW libraries. To compile the <code>fftw-wisdom</code>
Chris@42 117 (command-line) tool (see <a href="Wisdom-Utilities.html#Wisdom-Utilities">Wisdom Utilities</a>), compile
Chris@42 118 <code>tools/fftw-wisdom.c</code> and link it to the <code>libbench2</code> and FFTW
Chris@42 119 libraries
