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/prodrive/p3p440/Makefile | 16 ++++++++++------ board/prodrive/pdnb3/Makefile | 18 +++++++++++------- board/prodrive/pdnb3/config.mk | 2 +- 3 files changed, 22 insertions(+), 14 deletions(-) (limited to 'board/prodrive') diff --git a/board/prodrive/p3p440/Makefile b/board/prodrive/p3p440/Makefile index 47116d367..a47a0674c 100644 --- a/board/prodrive/p3p440/Makefile +++ b/board/prodrive/p3p440/Makefile @@ -1,5 +1,5 @@ # -# (C) Copyright 2002 +# (C) Copyright 2002-2006 # Wolfgang Denk, DENX Software Engineering, wd@denx.de. # # See file CREDITS for list of people who contributed to this @@ -23,11 +23,15 @@ include $(TOPDIR)/config.mk -LIB = lib$(BOARD).a +LIB = $(obj)lib$(BOARD).a -OBJS = $(BOARD).o +COBJS = $(BOARD).o SOBJS = init.o +SRCS := $(SOBJS:.o=.S) $(COBJS:.o=.c) +OBJS := $(addprefix $(obj),$(COBJS)) +SOBJS := $(addprefix $(obj),$(SOBJS)) + $(LIB): $(OBJS) $(SOBJS) $(AR) crv $@ $(OBJS) @@ -39,9 +43,9 @@ distclean: clean ######################################################################### -.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 ######################################################################### diff --git a/board/prodrive/pdnb3/Makefile b/board/prodrive/pdnb3/Makefile index f3cd5a3f1..32ffac0dc 100644 --- a/board/prodrive/pdnb3/Makefile +++ b/board/prodrive/pdnb3/Makefile @@ -23,12 +23,16 @@ include $(TOPDIR)/config.mk -LIB = lib$(BOARD).a +LIB = $(obj)lib$(BOARD).a -OBJS := flash.o pdnb3.o nand.o +COBJS := flash.o pdnb3.o nand.o -$(LIB): $(OBJS) $(SOBJS) - $(AR) crv $@ $^ +SRCS := $(SOBJS:.o=.S) $(COBJS:.o=.c) +OBJS := $(addprefix $(obj),$(COBJS)) +SOBJS := $(addprefix $(obj),$(SOBJS)) + +$(LIB): $(obj).depend $(OBJS) + $(AR) crv $@ $(OBJS) clean: rm -f $(SOBJS) $(OBJS) @@ -38,9 +42,9 @@ distclean: clean ######################################################################### -.depend: Makefile $(SOBJS:.o=.S) $(OBJS:.o=.c) - $(CC) -M $(CPPFLAGS) $(SOBJS:.o=.S) $(OBJS:.o=.c) > $@ +# defines $(obj).depend target +include $(SRCTREE)/rules.mk --include .depend +sinclude $(obj).depend ######################################################################### diff --git a/board/prodrive/pdnb3/config.mk b/board/prodrive/pdnb3/config.mk index 6b0f18b30..767075884 100644 --- a/board/prodrive/pdnb3/config.mk +++ b/board/prodrive/pdnb3/config.mk @@ -1,4 +1,4 @@ TEXT_BASE = 0x01f00000 # include NPE ethernet driver -BOARDLIBS = cpu/ixp/npe/libnpe.a +BOARDLIBS = $(obj)cpu/ixp/npe/libnpe.a -- cgit v1.2.3
