   3 # This Makefile fragment is meant to be included by packages that
   4 # require a Berkeley DB (BDB) implementation and that are not restricted
   5 # to a single one. The available BDB implementations are db1
   6 # (if builtin) and db[234].
   7 #
   8 # FIXME: This Makefile cannot handle packages that can use only a
   9 # subset of { db2 db3 db4 }.
  10 #
  11 # === User-settable variables ===
  12 #
  13 # BDB_DEFAULT
  14 #       This value represents the package we use when either a db-1.85
  15 #       interface isn't required, or a db-1.85 interface is required,
  16 #       but it's not built-in.
  17 #
  18 #       FIXME: Improve the wording of the text above so that one can
  19 #       understand it.
  20 #
  21 #       Possible: db1 db2 db3 db4 db5
  22 #       Default: db4
  23 #
  24 # BDB185_DEFAULT
  25 #       The package we use when a db-1.85 interface is required.
  26 #       It defaults to "db1" if it's built-in, or to ${BDB_DEFAULT}
  27 #       otherwise.
  28 #
  29 # === Package-settable variables ===
  30 #
  31 # BDB_ACCEPTED
  32 #       The list of Berkeley DB implementations that can be used by the
  33 #       package.
  34 #
  35 #       FIXME: If the list does not include db1 and does not include
  36 #       BDB_DEFAULT, the package will not build at the moment.
  37 #
  38 # === Variables set by this file ===
  39 #
  40 # BDB_TYPE
  41 #       The name of the selected BDB implementation.
  42 #
  43 # BDBBASE
  44 #       The base directory of the selected BDB implementation. It has
  45 #       subdirectories include/ and lib/.
  46 #
  47 # BDB_LIBS
  48 #       Linker flags to link against the BDB library.
  49
  50 # Note for when databases/db1 is imported:
  51 #   (1) Remove the section that conditionally sets the default
  52 #       value for BDB185_DEFAULT and always set it to be "db1".
  53 #   (2) Remove the special case for ${BDB_TYPE} == "db1" at the end.
  54 #   (3) Move mk/db1.builtin.mk to databases/db1/builtin.mk.
