Chris@82

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