| 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 | |

| 67 # `distclean' target. | |
