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