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 for Windows does not have the <code>Configure</code> program of Apache 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><code class="directive">LoadModule</code></code> directive. These module DLLs can be distributed and run on any Apache 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 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 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</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 LoadFile 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> <div class="example"><p><code>LoadFile libexec/libxmlparse.so</code></p></div></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 listof 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</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 LoadModule 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.
