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. --- tools/Makefile | 98 +++++++++++++++++++++++++++++++--------------------------- 1 file changed, 53 insertions(+), 45 deletions(-) (limited to 'tools/Makefile') diff --git a/tools/Makefile b/tools/Makefile index d3dcc7d..606f024 100644 --- a/tools/Makefile +++ b/tools/Makefile @@ -1,5 +1,5 @@ # -# (C) Copyright 2000-2003 +# (C) Copyright 2000-2006 # Wolfgang Denk, DENX Software Engineering, wd@denx.de. # # See file CREDITS for list of people who contributed to this @@ -21,22 +21,23 @@ # MA 02111-1307 USA # -BINS = img2srec$(SFX) mkimage$(SFX) envcrc$(SFX) gen_eth_addr$(SFX) bmp_logo$(SFX) +BIN_FILES = img2srec$(SFX) mkimage$(SFX) envcrc$(SFX) gen_eth_addr$(SFX) bmp_logo$(SFX) -OBJS = environment.o img2srec.o mkimage.o crc32.o envcrc.o gen_eth_addr.o bmp_logo.o +OBJ_LINKS = environment.o crc32.o +OBJ_FILES = img2srec.o mkimage.o envcrc.o gen_eth_addr.o bmp_logo.o ifeq ($(ARCH),mips) -BINS += inca-swap-bytes$(SFX) -OBJS += inca-swap-bytes.o +BIN_FILES += inca-swap-bytes$(SFX) +OBJ_FILES += inca-swap-bytes.o endif # Don't build by default #ifeq ($(ARCH),ppc) -#BINS += mpc86x_clk$(SFX) -#OBJS += mpc86x_clk.o +#BIN_FILES += mpc86x_clk$(SFX) +#OBJ_FILES += mpc86x_clk.o #endif -LOGO_H = $(TOPDIR)/include/bmp_logo.h +LOGO_H = $(OBJTREE)/include/bmp_logo.h ifeq ($(LOGO_BMP),) LOGO_BMP= logos/denx.bmp @@ -106,69 +107,76 @@ endif # include $(TOPDIR)/config.mk +# now $(obj) is defined +SRCS := $(addprefix $(obj),$(OBJ_LINKS:.o=.c)) $(OBJ_FILES:.o=.c) +BINS := $(addprefix $(obj),$(BIN_FILES)) + # # Use native tools and options # -CPPFLAGS = -idirafter ../include -DTEXT_BASE=$(TEXT_BASE) -DUSE_HOSTCC +CPPFLAGS = -idirafter $(SRCTREE)/include \ + -idirafter $(OBJTREE)/include2 \ + -idirafter $(OBJTREE)/include \ + -DTEXT_BASE=$(TEXT_BASE) -DUSE_HOSTCC CFLAGS = $(HOST_CFLAGS) $(CPPFLAGS) -O AFLAGS = -D__ASSEMBLY__ $(CPPFLAGS) CC = $(HOSTCC) STRIP = $(HOSTSTRIP) MAKEDEPEND = makedepend -all: .depend $(BINS) $(LOGO_H) subdirs +all: $(obj).depend $(BINS) $(LOGO_H) subdirs -envcrc$(SFX): envcrc.o crc32.o environment.o +$(obj)envcrc$(SFX): $(obj)envcrc.o $(obj)crc32.o $(obj)environment.o $(CC) $(CFLAGS) -o $@ $^ -img2srec$(SFX): img2srec.o +$(obj)img2srec$(SFX): $(obj)img2srec.o $(CC) $(CFLAGS) $(HOST_LDFLAGS) -o $@ $^ $(STRIP) $@ -mkimage$(SFX): mkimage.o crc32.o +$(obj)mkimage$(SFX): $(obj)mkimage.o $(obj)crc32.o $(CC) $(CFLAGS) $(HOST_LDFLAGS) -o $@ $^ $(STRIP) $@ -ncb$(SFX): ncb.o +$(obj)ncb$(SFX): $(obj)ncb.o $(CC) $(CFLAGS) $(HOST_LDFLAGS) -o $@ $^ $(STRIP) $@ -gen_eth_addr$(SFX): gen_eth_addr.o +$(obj)gen_eth_addr$(SFX): $(obj)gen_eth_addr.o $(CC) $(CFLAGS) $(HOST_LDFLAGS) -o $@ $^ $(STRIP) $@ -bmp_logo$(SFX): bmp_logo.o +$(obj)bmp_logo$(SFX): $(obj)bmp_logo.o $(CC) $(CFLAGS) $(HOST_LDFLAGS) -o $@ $^ $(STRIP) $@ -inca-swap-bytes$(SFX): inca-swap-bytes.o +$(obj)inca-swap-bytes$(SFX): $(obj)inca-swap-bytes.o $(CC) $(CFLAGS) $(HOST_LDFLAGS) -o $@ $^ $(STRIP) $@ -mpc86x_clk$(SFX): mpc86x_clk.o +$(obj)mpc86x_clk$(SFX): $(obj)mpc86x_clk.o $(CC) $(CFLAGS) $(HOST_LDFLAGS) -o $@ $^ $(STRIP) $@ -envcrc.o: envcrc.c -
