Help me understand "embedded.o" in src/makefile.housekeeping - wqlxx - 2014-06-06 02:31
Code:
# List of embedded images included in the last build of embedded.o.
# This is needed in order to correctly rebuild embedded.o whenever the
# list of objects changes.
#
EMBED := $(EMBEDDED_IMAGE) # Maintain backwards compatibility
EMBEDDED_LIST := $(BIN)/.embedded.list
ifeq ($(wildcard $(EMBEDDED_LIST)),)
EMBED_OLD := <invalid>
else
EMBED_OLD := $(shell cat $(EMBEDDED_LIST))
endif
ifneq ($(EMBED_OLD),$(EMBED))
$(shell $(ECHO) "$(EMBED)" > $(EMBEDDED_LIST))
endif
$(EMBEDDED_LIST) : $(MAKEDEPS)
VERYCLEANUP += $(EMBEDDED_LIST)
EMBEDDED_FILES := $(subst $(COMMA), ,$(EMBED))
EMBED_ALL := $(foreach i,$(call seq,1,$(words $(EMBEDDED_FILES))),\
EMBED ( $(i), \"$(word $(i), $(EMBEDDED_FILES))\",\
\"$(notdir $(word $(i),$(EMBEDDED_FILES)))\" ))
embedded_DEPS += $(EMBEDDED_FILES) $(EMBEDDED_LIST)
CFLAGS_embedded = -DEMBED_ALL="$(EMBED_ALL)"I don't know the ture meaning of "embedded images". I suppose that "embedded images" is the disk img (such as grldr, ipxe.lkrn or PE.iso) or otherwise meanings.

It refers to images embedded within the iPXE binary, such as an embedded script.
