# $NetBSD: bdb.buildlink3.mk,v 1.24 2010/06/02 12:11:52 adam Exp $
#
# This Makefile fragment is meant to be included by packages that
# require a Berkeley DB (BDB) implementation and that are not restricted
# to a single one. The available BDB implementations are db1
# (if builtin) and db[234].
#
# FIXME: This Makefile cannot handle packages that can use only a
# subset of { db2 db3 db4 }.
#
# === User-settable variables ===
#
# BDB_DEFAULT
# This value represents the package we use when either a db-1.85
# interface isn't required, or a db-1.85 interface is required,
# but it's not built-in.
#
# FIXME: Improve the wording of the text above so that one can
# understand it.
#
# Possible: db1 db2 db3 db4 db5
# Default: db4
#
# BDB185_DEFAULT
# The package we use when a db-1.85 interface is required.
# It defaults to "db1" if it's built-in, or to ${BDB_DEFAULT}
# otherwise.
#
# === Package-settable variables ===
#
# BDB_ACCEPTED
# The list of Berkeley DB implementations that can be used by the
# package.
#
# FIXME: If the list does not include db1 and does not include
# BDB_DEFAULT, the package will not build at the moment.
#
# === Variables set by this file ===
#
# BDB_TYPE
# The name of the selected BDB implementation.
#
# BDBBASE
# The base directory of the selected BDB implementation. It has
# subdirectories include/ and lib/.
#
# BDB_LIBS
# Linker flags to link against the BDB library.
# Note for when databases/db1 is imported:
# (1) Remove the section that conditionally sets the default
# value for BDB185_DEFAULT and always set it to be "db1".
# (2) Remove the special case for ${BDB_TYPE} == "db1" at the end.
# (3) Move mk/db1.builtin.mk to databases/db1/builtin.mk.
