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/mips/Makefile | 22 +++++++++++++--------- 1 file changed, 13 insertions(+), 9 deletions(-) (limited to 'cpu/mips/Makefile') diff --git a/cpu/mips/Makefile b/cpu/mips/Makefile index c8b30c7..f9a49df 100644 --- a/cpu/mips/Makefile +++ b/cpu/mips/Makefile @@ -1,5 +1,5 @@ # -# (C) Copyright 2003 +# (C) Copyright 2003-2006 # Wolfgang Denk, DENX Software Engineering, wd@denx.de. # # See file CREDITS for list of people who contributed to this @@ -23,23 +23,27 @@ include $(TOPDIR)/config.mk -LIB = lib$(CPU).a +LIB = $(obj)lib$(CPU).a START = start.o -OBJS = asc_serial.o au1x00_serial.o au1x00_eth.o au1x00_usb_ohci.o \ +COBJS = asc_serial.o au1x00_serial.o au1x00_eth.o au1x00_usb_ohci.o \ cpu.o interrupts.o incaip_clock.o SOBJS = incaip_wdt.o cache.o -all: .depend $(START) $(LIB) +SRCS := $(START:.o=.S) $(SOBJS:.o=.S) $(COBJS:.o=.c) +OBJS := $(addprefix $(obj),$(SOBJS) $(COBJS)) +START := $(addprefix $(obj),$(START)) -$(LIB): $(OBJS) $(SOBJS) - $(AR) crv $@ $(OBJS) $(SOBJS) +all: $(obj).depend $(START) $(LIB) + +$(LIB): $(OBJS) + $(AR) crv $@ $(OBJS) ######################################################################### -.depend: Makefile $(START:.o=.S) $(OBJS:.o=.c) - $(CC) -M $(CFLAGS) $(START:.o=.S) $(OBJS:.o=.c) > $@ +# defines $(obj).depend target +include $(SRCTREE)/rules.mk -sinclude .depend +sinclude $(obj).depend ######################################################################### -- cgit v1.1
