I have some trouble with making Makefile. This is a part of Makefile.
dirs := fwd common bp bp_manager $(XRTE_HASH)
VPATH_ = $(foreach dir,$(dirs),$(SRCDIR)/$(dir))
INC_ = $(foreach dir,$(dirs),$(wildcard $(dir)/*.h))
CFLAGS_ = $(foreach dir,$(dirs),-I$(SRCDIR)/$(dir))
SRCS-y_ = $(foreach dir,$(dirs),$(notdir $(wildcard $(dir)/*.c)))
VPATH += $(VPATH_)
INC += $(INC_)
CFLAGS += $(CFLAGS_)
SRCS-y += $(SRCS-y_)
check:
echo $(CFLAGS)
echo $(SRCS-y)
I thought Makefile is almost same with csh. Can you explain me why the "make" ignores functions? Thanks.
CFLAGS_ is just a string. $(CFLAGS_) is a variable's value. So you should have:
CFLAGS += $(CFLAGS_)
SRCS-y += $(SRCS-y_)
