|
|
cannam@95
|
59
|
|
cannam@95
|
60 <p>It should be relatively straightforward to compile FFTW even on non-Unix
|
|
cannam@95
|
61 systems lacking the niceties of a <code>configure</code> script. Basically,
|
|
cannam@95
|
62 you need to edit the <code>config.h</code> header (copy it from
|
|
cannam@95
|
63 <code>config.h.in</code>) to <code>#define</code> the various options and compiler
|
|
cannam@95
|
64 characteristics, and then compile all the ‘<samp><span class="samp">.c</span></samp>’ files in the
|
|
cannam@95
|
65 relevant directories.
|
|
cannam@95
|
66
|
|
cannam@95
|
67 <p>The <code>config.h</code> header contains about 100 options to set, each one
|
|
cannam@95
|
68 initially an <code>#undef</code>, each documented with a comment, and most of
|
|
cannam@95
|
69 them fairly obvious. For most of the options, you should simply
|
|
cannam@95
|
70 <code>#define</code> them to <code>1</code> if they are applicable, although a few
|
|
cannam@95
|
71 options require a particular value (e.g. <code>SIZEOF_LONG_LONG</code> should
|
|
cannam@95
|
72 be defined to the size of the <code>long long</code> type, in bytes, or zero
|
|
cannam@95
|
73 if it is not supported). We will likely post some sample
|
|
cannam@95
|
74 <code>config.h</code> files for various operating systems and compilers for
|
|
cannam@95
|
75 you to use (at least as a starting point). Please let us know if you
|
|
cannam@95
|
76 have to hand-create a configuration file (and/or a pre-compiled binary)
|
|
cannam@95
|
77 that you want to share.
|
|
cannam@95
|
78
|
|
cannam@95
|
79 <p>To create the FFTW library, you will then need to compile all of the
|
|
cannam@95
|
80 ‘<samp><span class="samp">.c</span></samp>’ files in the <code>kernel</code>, <code>dft</code>, <code>dft/scalar</code>,
|
|
cannam@95
|
81 <code>dft/scalar/codelets</code>, <code>rdft</code>, <code>rdft/scalar</code>,
|
|
cannam@95
|
82 <code>rdft/scalar/r2cf</code>, <code>rdft/scalar/r2cb</code>,
|
|
cannam@95
|
83 <code>rdft/scalar/r2r</code>, <code>reodft</code>, and <code>api</code> directories.
|
|
cannam@95
|
84 If you are compiling with SIMD support (e.g. you defined
|
|
cannam@95
|
85 <code>HAVE_SSE2</code> in <code>config.h</code>), then you also need to compile
|
|
cannam@95
|
86 the <code>.c</code> files in the <code>simd-support</code>,
|
|
cannam@95
|
87 <code>{dft,rdft}/simd</code>, <code>{dft,rdft}/simd/*</code> directories.
|
|
cannam@95
|
88
|
|
cannam@95
|
89 <p>Once these files are all compiled, link them into a library, or a shared
|
|
cannam@95
|
90 library, or directly into your program.
|
|
cannam@95
|
91
|
|
cannam@95
|
92 <p>To compile the FFTW test program, additionally compile the code in the
|
|
cannam@95
|
93 <code>libbench2/</code> directory, and link it into a library. Then compile
|
|
cannam@95
|
94 the code in the <code>tests/</code> directory and link it to the
|
|
cannam@95
|
95 <code>libbench2</code> and FFTW libraries. To compile the <code>fftw-wisdom</code>
|
|
cannam@95
|
96 (command-line) tool (see <a href="Wisdom-Utilities.html#Wisdom-Utilities">Wisdom Utilities</a>), compile
|
|
cannam@95
|
97 <code>tools/fftw-wisdom.c</code> and link it to the <code>libbench2</code> and FFTW
|
|
cannam@95
|
98 libraries
