Synopsis
</h2>
<p class="indent" style="white-space:nowrap;">
<code>AC_PROG_APACHE([version])</code>
</p>
<h2>
Description
</h2>
<div class="indent">
<p>
This macro searches for an installed apache server. If nothing was
specified when calling configure or just --with-apache, it searches in
/usr/local/apache/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin The
argument of --with-apache specifies the full pathname of the httpd
argument. For instance --with-apache=/usr/sbin/httpd.
</p>
<p>
If the version argument is given, AC_PROG_APACHE checks that the apache
server is this version number or higher.
</p>
<p>
If the apache server is not found, abort configuration with error message.
</p>
<p>
It defines the symbol APACHE if the server is found.
</p>
<p>
Files using apache should do the following:
</p>
<pre>
@APACHE@ -d /etc/httpd
</pre>
<p>
It defines the symbol APACHE_MODULES if a directory containing mod_env.* is
found in the default server root directory (obtained with httpd -V).
</p>
<p>
The httpd.conf file listing modules to be loaded dynamicaly can use
@APACHE_MODULES@ to grab them in the appropriate sub directory. For
instance:
</p>
<pre>
...
<IfModule mod_so.c>
LoadModule env_module @APACHE_MODULES@/mod_env.so
LoadModule config_log_module @APACHE_MODULES@/mod_log_config.so
...
</pre>
