gzip driver directory

GZIP_DIR := $(SRC_DIR)/gzip

compilation flags for the driver

ifeq ($(SYSTEM_ZLIB),) GZIP_COMPILE := $(CC) $(ANSIFLAGS) \ $I$(subst /,$(COMPILER_SEP),$(GZIP_DIR)) \ $(INCLUDE_FLAGS) \ $(FT_CFLAGS) else GZIP_COMPILE := $(CC) $(ANSIFLAGS) \ $(INCLUDE_FLAGS) \ $(FT_CFLAGS) endif

gzip support sources

All source and header files get loaded by `ftgzip.c' only if SYSTEM_ZLIB

is not defined (regardless whether we have a single' or amulti' build).

However, it doesn't harm if we add everything as a dependency

unconditionally.

GZIP_DRV_SRCS := $(GZIP_DIR)/adler32.c \ $(GZIP_DIR)/ftzconf.h \ $(GZIP_DIR)/infblock.c \ $(GZIP_DIR)/infblock.h \ $(GZIP_DIR)/infcodes.c \ $(GZIP_DIR)/infcodes.h \ $(GZIP_DIR)/inffixed.h \ $(GZIP_DIR)/inflate.c \ $(GZIP_DIR)/inftrees.c \ $(GZIP_DIR)/inftrees.h \ $(GZIP_DIR)/infutil.c \ $(GZIP_DIR)/infutil.h \ $(GZIP_DIR)/zlib.h \ $(GZIP_DIR)/zutil.c \ $(GZIP_DIR)/zutil.h

gzip driver object(s)

GZIP_DRV_OBJ is used during both single' andmulti' builds

GZIP_DRV_OBJ := $(OBJ_DIR)/ftgzip.$O

gzip main source file

GZIP_DRV_SRC := $(GZIP_DIR)/ftgzip.c
