# $NetBSD: bsd.options.mk,v 1.38 2005/06/06 13:54:51 dillo Exp $
|
|
#
|
|
# This Makefile fragment provides boilerplate code for standard naming
|
|
# conventions for handling per-package build options.
|
|
#
|
|
# Before including this file, the following variables can be defined:
|
|
#
|
|
# PKG_SUPPORTED_OPTIONS
|
|
# This is a list of build options supported by the package.
|
|
# This variable should be set in a package Makefile. E.g.,
|
|
#
|
|
# PKG_SUPPORTED_OPTIONS= kerberos ldap ssl
|
|
#
|
|
# PKG_OPTION_VAR (must be defined)
|
|
# The variable the user can set to enable or disable
|
|
# options specifically for this package.
|
|
#
|
|
# PKG_OPTIONS_OPTIONAL_GROUPS
|
|
# This is a list names of groups of mutually exclusive
|
|
# options. The options in each group are listed in
|
|
# PKG_OPTIONS_GROUP.<groupname>. The most specific
|
|
# setting of any option from the group takes precedence
|
|
# over all other options in the group. Options from
|
|
# the groups will be automatically added to
|
|
# PKG_SUPPORTED_OPTOINS.
|
|
#
|
|
# PKG_OPTIONS_REQUIRED_GROUPS
|
|
# Like PKG_OPTIONS_OPTIONAL_GROUPS, but building
|
|
# the packages will fail if no option from the group
|
|
# is selected.
|
|
#
|
|
# PKG_SUGGESTED_OPTIONS (defaults to empty)
|
|
# This is a list of build options which are enabled by default.
|
|
#
|
|
# PKG_OPTIONS_LEGACY_VARS
|
|
# This is a list of USE_VARIABLE:option pairs that
|
|
# map legacy /etc/mk.conf variables to their option
|
|
# counterparts.
|
|
#
|
|
# PKG_OPTIONS_LEGACY_OPTS
|
|
# This is a list of old-option:new-option pairs that
|
|
# map options that have been renamed to their new
|
|
# counterparts.
|
|
#
|
|
# PKG_LEGACY_OPTIONS
|
|
# A list of options implied by deprecated variables
|
|
# used. This can be used for cases that neither
|
|
# PKG_OPTIONS_LEGACY_VARS nor PKG_OPTIONS_LEGACY_OPTS
|
|
# can handle, e. g. when PKG_OPTIONS_VAR is renamed.
|
|
#
|
|
# PKG_OPTIONS_DEPRECATED_WARNINGS
|
|
# A list of warnings about deprecated variables or
|
|
# options used, and what to use instead.
|
|
#
|
|
# At least one of PKG_SUPPORTED_OPTIONS, PKG_OPTIONS_OPTIONAL_GROUPS,
|
|
# and PKG_OPTIONS_REQUIRED_GROUPS must be defined.
|
|
#
|
|
#
|
|
# Optionally, the user may define the following variables in /etc/mk.conf:
|
|
#
|
|
# PKG_DEFAULT_OPTIONS
|
|
# This variable can be used to override default
|
|
# options for every package. Options listed in this
|
|
# variable will be enabled in every package that
|
|
# supports them. If you prefix an option with `-',
|
|
# it will be disabled in every package.
|
|
#
|
|
# ${PKG_OPTIONS_VAR}
|
|
# This variable can be used to override default
|
|
# options and options listed in PKG_DEFAULT_OPTIONS.
|
|
# The syntax is the same as PKG_DEFAULT_OPTIONS.
|
|
#
|
|
# After including this file, the following variables are defined:
|
|
#
|
|
# PKG_OPTIONS
|
|
# This is the list of the selected build options, properly
|
|
# filtered to remove unsupported and duplicate options.
|
|
#
|
|
# Example usage:
|
|
#
|
