cannam@167: <h3 class="section">10.2 Installation on non-Unix systems</h3>
cannam@167:
cannam@167: <p>It should be relatively straightforward to compile FFTW even on non-Unix
cannam@167: systems lacking the niceties of a <code>configure</code> script. Basically,
cannam@167: you need to edit the <code>config.h</code> header (copy it from
cannam@167: <code>config.h.in</code>) to <code>#define</code> the various options and compiler
cannam@167: characteristics, and then compile all the ‘<samp>.c</samp>’ files in the
cannam@167: relevant directories.
cannam@167: </p>
cannam@167: <p>The <code>config.h</code> header contains about 100 options to set, each one
cannam@167: initially an <code>#undef</code>, each documented with a comment, and most of
cannam@167: them fairly obvious. For most of the options, you should simply
cannam@167: <code>#define</code> them to <code>1</code> if they are applicable, although a few
cannam@167: options require a particular value (e.g. <code>SIZEOF_LONG_LONG</code> should
cannam@167: be defined to the size of the <code>long long</code> type, in bytes, or zero
cannam@167: if it is not supported). We will likely post some sample
cannam@167: <code>config.h</code> files for various operating systems and compilers for
cannam@167: you to use (at least as a starting point). Please let us know if you
cannam@167: have to hand-create a configuration file (and/or a pre-compiled binary)
cannam@167: that you want to share.
cannam@167: </p>
cannam@167: <p>To create the FFTW library, you will then need to compile all of the
cannam@167: ‘<samp>.c</samp>’ files in the <code>kernel</code>, <code>dft</code>, <code>dft/scalar</code>,
cannam@167: <code>dft/scalar/codelets</code>, <code>rdft</code>, <code>rdft/scalar</code>,
cannam@167: <code>rdft/scalar/r2cf</code>, <code>rdft/scalar/r2cb</code>,
cannam@167: <code>rdft/scalar/r2r</code>, <code>reodft</code>, and <code>api</code> directories.
cannam@167: If you are compiling with SIMD support (e.g. you defined
cannam@167: <code>HAVE_SSE2</code> in <code>config.h</code>), then you also need to compile
cannam@167: the <code>.c</code> files in the <code>simd-support</code>,
cannam@167: <code>{dft,rdft}/simd</code>, <code>{dft,rdft}/simd/*</code> directories.
cannam@167: </p>
cannam@167: <p>Once these files are all compiled, link them into a library, or a shared
cannam@167: library, or directly into your program.
cannam@167: </p>
cannam@167: <p>To compile the FFTW test program, additionally compile the code in the
cannam@167: <code>libbench2/</code> directory, and link it into a library. Then compile
cannam@167: the code in the <code>tests/</code> directory and link it to the
cannam@167: <code>libbench2</code> and FFTW libraries. To compile the <code>fftw-wisdom</code>
cannam@167: (command-line) tool (see <a href="Wisdom-Utilities.html#Wisdom-Utilities">Wisdom Utilities</a>), compile
cannam@167: <code>tools/fftw-wisdom.c</code> and link it to the <code>libbench2</code> and FFTW
cannam@167: libraries
