From f93286397ed2a7084efb0362a43ee09f11702349 Mon Sep 17 00:00:00 2001 From: Marian Balakowicz Date: Fri, 1 Sep 2006 19:49:50 +0200 Subject: Add support for a saving build objects in a separate directory. Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory. --- cpu/arm920t/ks8695/Makefile | 21 ++++++++++++--------- 1 file changed, 12 insertions(+), 9 deletions(-) (limited to 'cpu/arm920t/ks8695') diff --git a/cpu/arm920t/ks8695/Makefile b/cpu/arm920t/ks8695/Makefile index ac49060..6342435 100644 --- a/cpu/arm920t/ks8695/Makefile +++ b/cpu/arm920t/ks8695/Makefile @@ -1,5 +1,5 @@ # -# (C) Copyright 2000-2005 +# (C) Copyright 2000-2006 # Wolfgang Denk, DENX Software Engineering, wd@denx.de. # # See file CREDITS for list of people who contributed to this @@ -23,21 +23,24 @@ include $(TOPDIR)/config.mk -LIB = lib$(SOC).a +LIB = $(obj)lib$(SOC).a -OBJS = interrupts.o serial.o +COBJS = interrupts.o serial.o SOBJS = lowlevel_init.o -all: .depend $(LIB) +SRCS := $(SOBJS:.o=.S) $(COBJS:.o=.c) +OBJS := $(addprefix $(obj),$(SOBJS) $(COBJS)) -$(LIB): $(OBJS) $(SOBJS) - $(AR) crv $@ $(OBJS) $(SOBJS) +all: $(obj).depend $(LIB) + +$(LIB): $(OBJS) + $(AR) crv $@ $(OBJS) ######################################################################### -.depend: Makefile $(SOBJS:.o=.S) $(OBJS:.o=.c) - $(CC) -M $(CFLAGS) $(SOBJS:.o=.S) $(OBJS:.o=.c) > $@ +# defines $(obj).depend target +include $(SRCTREE)/rules.mk -sinclude .depend +sinclude $(obj).depend ######################################################################### -- cgit v1.1
