Many modules will run on Windows with no or + little change from Unix, although others rely on aspects of the + Unix architecture which are not present in Windows, and will + not work.</p> + + <p>When a module does work, it can be added to the server in + one of two ways. As with Unix, it can be compiled into the + server. Because Apache httpd for Windows does not have the + <code>Configure</code> program of Apache httpd for Unix, the module's + source file must be added to the ApacheCore project file, and + its symbols must be added to the + <code>os\win32\modules.c</code> file.</p> + + <p>The second way is to compile the module as a DLL, a shared + library that can be loaded into the server at runtime, using + the <code class="directive">LoadModule</code> + directive. These module DLLs can be distributed and run on any + Apache httpd for Windows installation, without recompilation of the + server.</p> + + <p>To create a module DLL, a small change is necessary to the + module's source file: The module record must be exported from + the DLL (which will be created later; see below). To do this, + add the <code>AP_MODULE_DECLARE_DATA</code> (defined in the + Apache httpd header files) to your module's module record definition. + For example, if your module has:</p> + +<div class="example"><p><code> + module foo_module; +</code></p></div> + + <p>Replace the above with:</p> +<div class="example"><p><code> + module AP_MODULE_DECLARE_DATA foo_module; +</code></p></div> + + <p>Note that this will only be activated on Windows, so the + module can continue to be used, unchanged, with Unix if needed. + Also, if you are familiar with <code>.DEF</code> files, you can + export the module record with that method instead.</p> + + <p>Now, create a DLL containing your module. You will need to + link this against the libhttpd.lib export library that is + created when the libhttpd.dll shared library is compiled. You + may also have to change the compiler settings to ensure that + the Apache httpd header files are correctly located. You can find + this library in your server root's modules directory. It is + best to grab an existing module .dsp file from the tree to + assure the build environment is configured correctly, or + alternately compare the compiler and link options to your + .dsp.</p> + + <p>This should create a DLL version of your module. Now simply + place it in the <code>modules</code> directory of your server + root, and use the <code class="directive">LoadModule</code> + directive to load it.</p> + +</div> +<div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div> +<div class="directive-section"><h2><a name="LoadFile" id="LoadFile">LoadFile</a> <a name="loadfile" id="loadfile">Directive</a></h2> +<table class="directive"> +<tr><th><a href="directive-dict.html#Description">Description:</a></th><td>Link in the named object file or library</td></tr> +<tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>LoadFile <em>filename</em> [<em>filename</em>] ...</code></td></tr> +<tr><th><a href="directive-dict.html#Context">Context:</a></th><td>server config, virtual host</td></tr> +<tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Extension</td></tr> +<tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_so</td></tr> +</table> + + <p>The <code class="directive">LoadFile</code> directive links in the named object files or + libraries when the server is started or restarted; this is used + to load additional code which may be required for some module + to work. <em>Filename</em> is either an absolute path or + relative to <a href="core.html#serverroot">ServerRoot</a>.</p> + + <p>For example:</p> + + <pre class="prettyprint lang-config">LoadFile "libexec/libxmlparse.so"</pre> + + + +</div> +<div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div> +<div class="directive-section"><h2><a name="LoadModule" id="LoadModule">LoadModule</a> <a name="loadmodule" id="loadmodule">Directive</a></h2> +<table class="directive"> +<tr><th><a href="directive-dict.html#Description">Description:</a></th><td>Links in the object file or library, and adds to the list +of active modules</td></tr> +<tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>LoadModule <em>module filename</em></code></td></tr> +<tr><th><a href="directive-dict.html#Context">Context:</a></th><td>server config, virtual host</td></tr> +<tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Extension</td></tr> +<tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_so</td></tr> +</table> + <p>The <code class="directive">LoadModule</code> directive links in the object file or library + <em>filename</em> and adds the module structure named + <em>module</em> to the list of active modules. <em>Module</em> + is the name of the external variable of type + <code>module</code> in the file, and is listed as the <a href="module-dict.html#ModuleIdentifier">Module Identifier</a> + in the module documentation.</p> + + <p>For example:</p> + + <pre class="prettyprint lang-config">LoadModule status_module "modules/mod_status.so"</pre> + + + <p>loads the named module from the modules subdirectory of the + ServerRoot.</p> + +</div> +</div> +<div class="bottomlang"> +<p><span>Available Languages: </span><a href="../en/mod/mod_so.html" title="English"> en </a> | +<a href="../fr/mod/mod_so.html" hreflang="fr" rel="alternate" title="Français"> fr </a> | +<a href="../ja/mod/mod_so.html" hreflang="ja" rel="alternate" title="Japanese"> ja </a> | +<a href="../ko/mod/mod_so.html" hreflang="ko" rel="alternate" title="Korean"> ko </a> | +<a href="../tr/mod/mod_so.html" hreflang="tr" rel="alternate" title="Türkçe"> tr </a></p> +</div><div class="top"><a href="#page-header"><img src="../images/up.gif" alt="top" /></a></div><div class="section"><h2><a id="comments_section" name="comments_section">Comments</a></h2><div class="warning"><strong>Notice:</strong><br />This is not a Q&A section.
