Synopsis

AC_PROG_HTTPD

Description

Check for Apache's 'httpd', let script continue if exists & works, pops up error message if not.

Testing of functionality is by checking its compile settings

Besides checking existence, this macro also set these environment variables upon completion:

    HTTPD                    = which httpd
    HTTPD_ROOT               = Apache's root directory, specified when compiled / run with -d option
    HTTPD_SERVER_ROOT        = Directory for Apache's essential files, e.g. access logs / error logs / modules / scripts.
    HTTPD_SERVER_CONFIG_FILE = Full-path of the 'httpd.conf' file
    HTTPD_USER               = Which user that httpd runs as
    HTTPD_GROUP              = Which group that httpd runs as
    HTTPD_DOC_HOME           = Document directory, taken as the first DocumentRoot path found in httpd.conf
    HTTPD_SCRIPT_HOME        = CGI script directory, taken as the first ScriptAlias path found in httpd.conf
