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. --- drivers/sk98lin/Makefile | 26 ++++++++++++++++---------- 1 file changed, 16 insertions(+), 10 deletions(-) (limited to 'drivers/sk98lin') diff --git a/drivers/sk98lin/Makefile b/drivers/sk98lin/Makefile index 8ee0e216cd..ac21e02133 100644 --- a/drivers/sk98lin/Makefile +++ b/drivers/sk98lin/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 @@ -24,15 +24,19 @@ # # Makefile for the SysKonnect SK-98xx device driver. # + include $(TOPDIR)/config.mk -LIB := libsk98lin.a +LIB := $(obj)libsk98lin.a + +COBJS := skge.o skaddr.o skgehwt.o skgeinit.o skgepnmi.o skgesirq.o \ + ski2c.o sklm80.o skqueue.o skrlmt.o sktimer.o skvpd.o \ + skxmac2.o skcsum.o #skproc.o -OBJS := skge.o skaddr.o skgehwt.o skgeinit.o skgepnmi.o skgesirq.o \ - ski2c.o sklm80.o skqueue.o skrlmt.o sktimer.o skvpd.o \ - skxmac2.o skcsum.o #skproc.o +COBJS += uboot_skb.o uboot_drv.o -OBJS += uboot_skb.o uboot_drv.o +SRCS := $(COBJS:.o=.c) +OBJS := $(addprefix $(obj),$(COBJS)) # DBGDEF = \ # -DDEBUG @@ -84,18 +88,20 @@ endif EXTRA_CFLAGS += -I. -DSK_USE_CSUM $(DBGDEF) CFLAGS += $(EXTRA_CFLAGS) +HOST_CFLAGS += $(EXTRA_CFLAGS) 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
