This is achieved by building a dynamic shared object (DSO) from one or more source or object <var>files</var> which then can be loaded into the Apache server under runtime via the <code class="directive"><a href="../mod/mod_so.html#loadmodule">LoadModule</a></code> directive from <code class="module"><a href="../mod/mod_so.html">mod_so</a></code>.</p> <p>So to use this extension mechanism your platform has to support the DSO feature and your Apache <code class="program"><a href="../programs/httpd.html">httpd</a></code> binary has to be built with the <code class="module"><a href="../mod/mod_so.html">mod_so</a></code> module. The <code>apxs</code> tool automatically complains if this is not the case. You can check this yourself by manually running the command</p> <div class="example"><p><code> $ httpd -l </code></p></div> <p>The module <code class="module"><a href="../mod/mod_so.html">mod_so</a></code> should be part of the displayed list. If these requirements are fulfilled you can easily extend your Apache server's functionality by installing your own modules with the DSO mechanism by the help of this <code>apxs</code> tool:</p> <div class="example"><p><code> $ apxs -i -a -c mod_foo.c<br /> gcc -fpic -DSHARED_MODULE -I/path/to/apache/include -c mod_foo.c<br /> ld -Bshareable -o mod_foo.so mod_foo.o<br /> cp mod_foo.so /path/to/apache/modules/mod_foo.so<br /> chmod 755 /path/to/apache/modules/mod_foo.so<br /> [activating module `foo' in /path/to/apache/etc/httpd.conf]<br /> $ apachectl restart<br /> /path/to/apache/sbin/apachectl restart: httpd not running, trying to start<br /> [Tue Mar 31 11:27:55 1998] [debug] mod_so.c(303): loaded module foo_module<br /> /path/to/apache/sbin/apachectl restart: httpd started<br /> $ _ </code></p></div> <p>The arguments <var>files</var> can be any C source file (.c), a object file (.o) or even a library archive (.a). The <code>apxs</code> tool automatically recognizes these extensions and automatically used the C source files for compilation while just using the object and archive files for the linking phase. But when using such pre-compiled objects make sure they are compiled for position independent code (PIC) to be able to use them for a dynamically loaded shared object. For instance with GCC you always just have to use <code>-fpic</code>. For other C compilers consult its manual page or at watch for the flags <code>apxs</code> uses to compile the object files.</p> <p>For more details about DSO support in Apache read the documentation of <code class="module"><a href="../mod/mod_so.html">mod_so</a></code> or perhaps even read the <code>src/modules/standard/mod_so.c</code> source file.</p></div><div id="quickview"><ul id="toc"><li><img alt="" src="../images/down.gif" /> <a href="#synopsis">Synopsis</a></li><li><img alt="" src="../images/down.gif" /> <a href="#options">Options</a></li><li><img alt="" src="../images/down.gif" /> <a href="#examples">Examples</a></li></ul><h3>See also</h3><ul class="seealso"><li><code class="program"><a href="../programs/apachectl.html">apachectl</a></code></li><li><code class="program"><a href="../programs/httpd.html">httpd</a></code></li></ul></div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="section"><h2><a name="synopsis" id="synopsis">Synopsis</a></h2> <p><code><strong>apxs</strong> -<strong>g</strong> [ -<strong>S</strong> <var>name</var>=<var>value</var> ] -<strong>n</strong> <var>modname</var></code></p> <p><code><strong>apxs</strong> -<strong>q</strong> [ -<strong>S</strong> <var>name</var>=<var>value</var> ] <var>query</var> ...</code></p> <p><code><strong>apxs</strong> -<strong>c</strong> [ -<strong>S</strong> <var>name</var>=<var>value</var> ] [ -<strong>o</strong> <var>dsofile</var> ] [ -<strong>I</strong> <var>incdir</var> ] [ -<strong>D</strong> <var>name</var>=<var>value</var> ] [ -<strong>L</strong> <var>libdir</var> ] [ -<strong>l</strong> <var>libname</var> ] [ -<strong>Wc,</strong><var>compiler-flags</var> ] [ -<strong>Wl,</strong><var>linker-flags</var> ] <var>files</var> ...</code></p> <p><code><strong>apxs</strong> -<strong>i</strong> [ -<strong>S</strong> <var>name</var>=<var>value</var> ] [ -<strong>n</strong> <var>modname</var> ] [ -<strong>a</strong> ] [ -<strong>A</strong> ] <var>dso-file</var> ...</code></p> <p><code><strong>apxs</strong> -<strong>e</strong> [ -<strong>S</strong> <var>name</var>=<var>value</var> ] [ -<strong>n</strong> <var>modname</var> ] [ -<strong>a</strong> ] [ -<strong>A</strong> ] <var>dso-file</var> ...</code></p></div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="section"><h2><a name="options" id="options">Options</a></h2> <h3><a name="options.common" id="options.common">Common Options</a></h3> <dl> <dt><code>-n <var>modname</var></code></dt> <dd>This explicitly sets the module name for the <code>-i</code> (install) and <code>-g</code> (template generation) option.
