  20 # The following variables (set by other Makefile components, in the
  21 # environment, or on the command line) are used:
  22 #
  23 #   BUILD_DIR      The architecture dependent directory,
  24 #                  e.g. `$(TOP_DIR)/builds/unix'.  Added to INCLUDES also.
  25 #
  26 #   OBJ_DIR        The directory in which object files are created.
  27 #
  28 #   LIB_DIR        The directory in which the library is created.
  29 #
  30 #   DOC_DIR        The directory in which the API reference is created.
  31 #
  32 #   INCLUDES       A list of directories to be included additionally.
  33 #
  34 #   DEVEL_DIR      Development directory which is added to the INCLUDES
  35 #                  variable before the standard include directories.
  36 #
  37 #   CFLAGS         Compilation flags.  This overrides the default settings
  38 #                  in the platform-specific configuration files.
  39 #
  40 #   FTSYS_SRC      If set, its value is used as the name of a replacement
  41 #                  file for `src/base/ftsystem.c'.
  42 #
  43 #   FTDEBUG_SRC    If set, its value is used as the name of a replacement
  44 #                  file for `src/base/ftdebug.c'.  [For a normal build, this
  45 #                  file does nothing.]
  46 #
  47 #   FTMODULE_H     The file which contains the list of module classes for
  48 #                  the current build.  Usually, this is automatically
  49 #                  created by `modules.mk'.
  50 #
  51 #   BASE_OBJ_S
  52 #   BASE_OBJ_M     A list of base objects (for single object and multiple
  53 #                  object builds, respectively).  Set up in
  54 #                  `src/base/rules.mk'.
  55 #
  56 #   BASE_EXT_OBJ   A list of base extension objects.  Set up in
  57 #                  `src/base/rules.mk'.
  58 #
  59 #   DRV_OBJ_S
  60 #   DRV_OBJ_M      A list of driver objects (for single object and multiple
  61 #                  object builds, respectively).  Set up cumulatively in
  62 #                  `src/<driver>/rules.mk'.
  63 #
  64 #   CLEAN
  65 #   DISTCLEAN      The sub-makefiles can append additional stuff to these two
  66 #                  variables which is to be removed for the `clean' resp.
