6.14. Web Applications, Apache and PHP

6.14.1. Apache

Table 6.16. Variables for Ports That Use Apache
USE_APACHEThe port requires Apache. Possible values: yes (gets any version), 22, 24, 22-24, 22+, etc. The default APACHE version is 22. More details are available in ports/Mk/bsd.apache.mk and at wiki.freebsd.org/Apache/.
APXSFull path to the apxs binary. Can be overridden in the port.
HTTPDFull path to the httpd binary. Can be overridden in the port.
APACHE_VERSIONThe version of present Apache installation (read-only variable). This variable is only available after inclusion of bsd.port.pre.mk. Possible values: 22, 24.
APACHEMODDIRDirectory for Apache modules. This variable is automatically expanded in pkg-plist.
APACHEINCLUDEDIRDirectory for Apache headers. This variable is automatically expanded in pkg-plist.
APACHEETCDIRDirectory for Apache configuration files. This variable is automatically expanded in pkg-plist.

Table 6.17. Useful Variables for Porting Apache Modules
MODULENAMEName of the module. Default value is PORTNAME. Example: mod_hello
SHORTMODNAMEShort name of the module. Automatically derived from MODULENAME, but can be overridden. Example: hello
AP_FAST_BUILDUse apxs to compile and install the module.
AP_GENPLISTAlso automatically creates a pkg-plist.
AP_INCAdds a directory to a header search path during compilation.
AP_LIBAdds a directory to a library search path during compilation.
AP_EXTRASAdditional flags to pass to apxs.

6.14.2. Web Applications

Web applications must be installed into PREFIX/www/appname. This path is available both in Makefile and in pkg-plist as WWWDIR, and the path relative to PREFIX is available in Makefile as WWWDIR_REL.

The user and group of web server process are available as WWWOWN and WWWGRP, in case the ownership of some files needs to be changed. The default values of both are www. Use WWWOWN?= myuser and WWWGRP?= mygroup if the port needs different values. This allows the user to override them easily.

Do not depend on Apache unless the web app explicitly needs Apache. Respect that users may wish to run a web app on different web server than Apache.

6.14.3. PHP

Table 6.18. Variables for Ports That Use PHP
USE_PHPThe port requires PHP. The value yes adds a dependency on PHP. The list of required PHP extensions can be specified instead. Example: pcre xml gettext
DEFAULT_PHP_VERSelects which major version of PHP will be installed as a dependency when no PHP is installed yet. Default is 5. Possible values: 4, 5
IGNORE_WITH_PHPThe port does not work with PHP of the given version. Possible values: 4, 5
USE_PHPIZEThe port will be built as a PHP extension.
USE_PHPEXTThe port will be treated as a PHP extension, including installation and registration in the extension registry.
USE_PHP_BUILDSet PHP as a build dependency.
WANT_PHP_CLIWant the CLI (command line) version of PHP.
WANT_PHP_CGIWant the CGI version of PHP.
WANT_PHP_MODWant the Apache module version of PHP.
WANT_PHP_SCRWant the CLI or the CGI version of PHP.
WANT_PHP_WEBWant the Apache module or the CGI version of PHP.

6.14.4. PEAR Modules

Porting PEAR modules is a very simple process.

Use the variables FILES, TESTS, DATA, SQLS, SCRIPTFILES, DOCS and EXAMPLES to list the files to install. All listed files will be automatically installed into the appropriate locations and added to pkg-plist.

Include ${PORTSDIR}/devel/pear/bsd.pear.mk on the last line of the Makefile.
