# $NetBSD: bsd.options.mk,v 1.67 2008/02/18 14:30:40 obache 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_OPTIONS_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 of 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_OPTIONS. # # PKG_OPTIONS_REQUIRED_GROUPS # Like PKG_OPTIONS_OPTIONAL_GROUPS, but building # the packages will fail if no option from the group # is selected. # # PKG_OPTIONS_NONEMPTY_SETS # This is a list of names of sets of options. At # least one option from each set must be selected. # The options in each set are listed in # PKG_OPTIONS_SET.<setname>. Options from the sets # will be automatically added to PKG_SUPPORTED_OPTIONS. # # 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. # # If none of PKG_SUPPORTED_OPTIONS, PKG_OPTIONS_OPTIONAL_GROUPS, # PKG_OPTIONS_REQUIRED_GROUPS, and PKG_OPTIONS_NONEMPTY_SETS are # defined, PKG_OPTIONS is set to the empty list and the package # is otherwise treated as not using the options framework. # # # 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. # .if !defined(BSD_OPTIONS_MK) BSD_OPTIONS_MK= # defined # To add options support to a package, here is an example for an # options.mk file.
