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. --- board/evb64260/Makefile | 18 ++++++++++++------ 1 file changed, 12 insertions(+), 6 deletions(-) (limited to 'board/evb64260/Makefile') diff --git a/board/evb64260/Makefile b/board/evb64260/Makefile index c493d6cf9..b28372d81 100644 --- a/board/evb64260/Makefile +++ b/board/evb64260/Makefile @@ -1,4 +1,7 @@ # +# (C) Copyright 2006 +# Wolfgang Denk, DENX Software Engineering, wd@denx.de. +# # (C) Copyright 2001 # Josh Huber , Mission Critical Linux, Inc. # @@ -23,22 +26,25 @@ include $(TOPDIR)/config.mk -LIB = lib$(BOARD).a +LIB = $(obj)lib$(BOARD).a SOBJS = misc.o -OBJS = $(BOARD).o flash.o serial.o memory.o pci.o \ +COBJS = $(BOARD).o flash.o serial.o memory.o pci.o \ eth.o eth_addrtbl.o mpsc.o i2c.o \ sdram_init.o zuma_pbb.o intel_flash.o zuma_pbb_mbox.o +SRCS := $(SOBJS:.o=.S) $(COBJS:.o=.c) +OBJS := $(addprefix $(obj),$(COBJS)) +SOBJS := $(addprefix $(obj),$(SOBJS)) -$(LIB): .depend $(OBJS) $(SOBJS) +$(LIB): $(obj).depend $(OBJS) $(SOBJS) $(AR) crv $@ $(OBJS) $(SOBJS) ######################################################################### -.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 v1.2.3
