# $NetBSD: bsd.options.mk,v 1.17 2005/04/28 18:40:35 jlam Exp $

|
#
|
|
# This Makefile fragment provides boilerplate code for standard naming
|
|
# conventions for handling per-package build options.
|
|
#
|
|
# Before including this file, the following variables should be defined:
|
|
#
|
|
# PKG_OPTIONS_VAR
|
|
# This is a list of the name of the make(1) variables that
|
|
# contain the options the user wishes to select. This
|
|
# variable should be set in a package Makefile. E.g.,
|
|
#
|
|
# PKG_OPTIONS_VAR= WIBBLE_OPTIONS
|
|
# or
|
|
# PKG_OPTIONS_VAR= FOO_OPTIONS BAR_OPTIONS
|
|
#
|
|
# 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
|
|
#
|
|
# Optionally, the following variables may also be defined:
|
|
#
|
|
# PKG_DEFAULT_OPTIONS
|
|
# This is a list the options that should be built into
|
|
# every package, if that option is supported. This
|
|
# variable should be set in /etc/mk.conf.
|
|
#
|
|
# ${PKG_OPTIONS_VAR} (the variables named in PKG_OPTIONS_VAR)
|
|
# These variables list the selected build options and
|
|
# override any default options given in PKG_DEFAULT_OPTIONS.
|
|
# If any of the options begin with a '-', then that option
|
|
# is always removed from the selected build options, e.g.
|
|
#
|
|
# PKG_DEFAULT_OPTIONS= kerberos ldap sasl
|
|
# PKG_OPTIONS_VAR= WIBBLE_OPTIONS
|
|
# WIBBLE_OPTIONS= ${PKG_DEFAULT_OPTIONS} -sasl
|
|
# # implies PKG_OPTIONS == "kerberos ldap"
|
|
# or
|
|
# PKG_OPTIONS_VAR= WIBBLE_OPTIONS
|
|
# WIBBLE_OPTIONS= kerberos -ldap ldap
|
|
# # implies PKG_OPTIONS == "kerberos"
|
|
#
|
|
# This variable should be set in /etc/mk.conf.
|
|
#
|
|
# PKG_FAIL_UNSUPPORTED_OPTIONS
|
|
# If this is set to "yes", then the presence of unsupported
|
|
# options in PKG_OPTIONS.<pkg> (see below) causes the build
|
|
# to fail. Set this to "no" to silently ignore unsupported
|
|
# options. Default: "no".

# After including this file, the following variables are defined:

|
|
# filtered to remove unsupported and duplicate options.
