Documentation

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.

If the version argument is given, AC_PROG_APACHE checks that the apache server is this version number or higher.

If the apache server is not found, abort configuration with error message.

It defines the symbol APACHE if the server is found.

Files using apache should do the following:

 @APACHE@ -d /etc/httpd

It defines the symbol APACHE_MODULES if a directory containing mod_env.* is found in the default server root directory (obtained with httpd -V).

The httpd.conf file listing modules to be loaded dynamicaly can use @APACHE_MODULES@ to grab them in the appropriate sub directory. For instance:

...
<IfModule mod_so.c>
LoadModule env_module         @APACHE_MODULES@/mod_env.so
LoadModule config_log_module  @APACHE_MODULES@/mod_log_config.so
...
