<em class="replaceable"><code>c::build-program</code></em>. The description of this function is as
follows. Care should be taken that <em class="replaceable"><code>image-name</code></em> differs from any
filename in <em class="replaceable"><code>lisp-files</code></em>.</p><div class="blockquote"><blockquote class="blockquote"><pre class="screen"><a class="indexterm" name="id675435"></a>— Function: <code class="function">c:build-program</code> <code class="varname">{</code><code class="varname">image-name</code> <code class="varname">&key</code> <code class="varname">lisp-files</code> <code class="varname">ld-flags</code> <code class="varname">prologue-code</code> <code class="varname">epilogue-code</code><code class="varname">}</code></pre><p>This function builds a lisp image up from the core lisp library, plus all

initialization process of the lisp image. In order to build the executable,
<em class="replaceable"><code>c:build-program</code></em> first writes down a piece of C code which initializes the
lisp environment. You can customize the initialization process by suppling code
to be executed before (<em class="replaceable"><code>prologue-code</code></em>) or after (<em class="replaceable"><code>epilogue-code</code></em>)
setting up the lisp environment. Typically <em class="replaceable"><code>prologue-code</code></em> defaults to an
empty string, while <em class="replaceable"><code>epilogue-code</code></em> invokes the classical lisp
<em class="replaceable"><code>top-level</code></em>. Additionally, as a convenience, <em class="replaceable"><code>epilogue-code</code></em> can
be either a string with C code or also a list with a lisp form, which
will be interpreted at run time.</p></blockquote></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="ch24s02.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="ch24.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="ch24s04.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">1.2. Compiling files </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> 1.4. Building libraries</td></tr></table></div></body></html>
