From f93286397ed2a7084efb0362a43ee09f11702349 Mon Sep 17 00:00:00 2001 From: Marian Balakowicz <m8@semihalf.com> 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/ixp/Makefile | 18 +++++++++++------- cpu/ixp/npe/Makefile | 23 ++++++++++++++++------- 2 files changed, 27 insertions(+), 14 deletions(-) (limited to 'cpu/ixp') diff --git a/cpu/ixp/Makefile b/cpu/ixp/Makefile index ba2e589..2867270 100644 --- a/cpu/ixp/Makefile +++ b/cpu/ixp/Makefile @@ -1,5 +1,5 @@ # -# (C) Copyright 2000, 2002 +# (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 +23,25 @@ include $(TOPDIR)/config.mk -LIB = lib$(CPU).a +LIB = $(obj)lib$(CPU).a START = start.o -OBJS = serial.o interrupts.o cpu.o timer.o pci.o +COBJS = serial.o interrupts.o cpu.o timer.o pci.o -all: .depend $(START) $(LIB) +SRCS := $(START:.o=.S) $(SOBJS:.o=.S) $(COBJS:.o=.c) +OBJS := $(addprefix $(obj),$(SOBJS) $(COBJS)) +START := $(addprefix $(obj),$(START)) + +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 ######################################################################### diff --git a/cpu/ixp/npe/Makefile b/cpu/ixp/npe/Makefile index 937de9d..412b418 100644 --- a/cpu/ixp/npe/Makefile +++ b/cpu/ixp/npe/Makefile @@ -23,11 +23,13 @@ include $(TOPDIR)/config.mk -LIB := libnpe.a +LIB := $(obj)libnpe.a -CFLAGS += -I$(TOPDIR)/cpu/ixp/npe/include -DCONFIG_IXP425_COMPONENT_ETHDB +LOCAL_CFLAGS += -I$(TOPDIR)/cpu/ixp/npe/include -DCONFIG_IXP425_COMPONENT_ETHDB +CFLAGS += $(LOCAL_CFLAGS) +HOST_CFLAGS += $(LOCAL_CFLAGS) -OBJS := npe.o \ +COBJS := npe.o \ miiphy.o \ IxOsalBufferMgt.o \ IxOsalIoMem.o \ @@ -78,14 +80,21 @@ OBJS := npe.o \ IxNpeMhSolicitedCbMgr.o \ IxNpeMhUnsolicitedCbMgr.o + +SRCS := $(START:.o=.S) $(SOBJS:.o=.S) $(COBJS:.o=.c) +OBJS := $(addprefix $(obj),$(SOBJS) $(COBJS)) +START := $(addprefix $(obj),$(START)) + all: $(LIB) -$(LIB): $(OBJS) +$(LIB): $(obj).depend $(OBJS) $(AR) crv $@ $(OBJS) ######################################################################### -.depend: Makefile $(OBJS:.o=.c) - $(CC) -M $(CFLAGS) $(OBJS:.o=.c) > $@ +# defines $(obj).depend target +include $(SRCTREE)/rules.mk -sinclude .depend +sinclude $(obj).depend + +######################################################################### -- cgit v1.1
