I am trying to understand a second level makefile of uboot (this makefile was in a sub directory) a) What is the difference between $(COBJS:.o=.c) and COBJS := test_main.o b) What is the meaning of $(call cmd_link_o_target, $(OBJS)). What is the cmd_link_o_target and what is the call statement doing c) Does this line creating 2 targets ? ALL := $(obj).depend $(LIB) ===================================Makefile=================== include $(TOPDIR)/config.mk LIB = $(obj)libtest.o SOBJS := test.o COBJS := test_main.o COBJS += diagnostic.o SRCS := $(SOBJS:.o=.S) $(COBJS:.o=.c) OBJS := $(addprefix $(obj),$(COBJS) $(SOBJS)) ALL := $(obj).depend $(LIB) all: $(ALL) $(LIB): $(OBJS) $(call cmd_link_o_target, $(OBJS)) ######################################################################### # defines $(obj).depend target include $(SRCTREE)/rules.mk sinclude $(obj).depend ######################################################################### -- -mj _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
