Some large applications can be built in a number of configurations, adding functionality if one of a number of libraries or applications is available. Examples include choice of natural (human) language, GUI versus command-line, or type of database to support. Since not all users want those libraries or applications, the ports system provides hooks that the port author can use to control which configuration should be built. Supporting these properly will make users happy, and effectively provide 2 or more ports for the price of one.
These variables are designed to be set by the system administrator. There are many that are standardized in ports/Mk/bsd.*.mk; others are not, which can be confusing. If you need to add such a configuration variable, please consider using one of the ones from the following list.
Note: You should not assume that a WITH_* necessarily has a corresponding WITHOUT_* variable and vice versa. In general, the default is simply assumed.
Note: Unless otherwise specified, these variables are only tested for being set or not set, rather than being set to some kind of variable such as YES or NO.
Table 5-2. The WITH_* and WITHOUT_* variables
| Variable | Means |
|---|---|
| WITH_APACHE2 | If set, use www/apache2 instead of the default of www/apache. |
| WITH_BERKELEY_DB | Define this variable to specify the ability to use a variant of the Berkeley database package such as databases/db41. An associated variable, WITH_BDB_VER, may be set to values such as 2, 3, 4, 41 or 42. |
| WITH_MYSQL | Define this variable to specify the ability to use a variant of the MySQL database package such as databases/mysql40-server. An associated variable, WANT_MYSQL_VER, may be set to values such as 323, 40, 41, or 50. |
| WITHOUT_NLS | If set, says that internationalization is not needed, which can save compile time. By default, internationalization is used. |
| WITH_OPENSSL_BASE | Use the version of OpenSSL in the base system. |
| WITH_OPENSSL_PORT | Use the version of OpenSSL from security/openssh, overwriting the version that was originally installed in the base system. |
| WITH_POSTGRESQL | Define this variable to specify the ability to use a variant of the PostGreSQL database package such as databases/postgresql72. |
| WITHOUT_X11 | If the port can be built both with and without X support, then it should normally be built with X support. If this variable is defined, then the version that does not have X support should be built instead. |
