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/gdb/Makefile | 23 +++++++++++++++-------- 1 file changed, 15 insertions(+), 8 deletions(-) (limited to 'tools/gdb') diff --git a/tools/gdb/Makefile b/tools/gdb/Makefile index e7618b7..dbcb91f 100644 --- a/tools/gdb/Makefile +++ b/tools/gdb/Makefile @@ -1,4 +1,7 @@ # +# (C) Copyright 2006 +# Wolfgang Denk, DENX Software Engineering, wd@denx.de. +# # (C) Copyright 2000 # Murray Jensen # @@ -25,7 +28,11 @@ include $(TOPDIR)/config.mk BINS = gdbsend gdbcont -OBJS = gdbsend.o gdbcont.o error.o remote.o serial.o +COBJS = gdbsend.o gdbcont.o error.o remote.o serial.o + +OBJS := $(addprefix $(obj),$(COBJS)) +SRCS := $(COBJS:.o=.c) +BINS := $(addprefix $(obj),$(BINS)) # # Use native tools and options @@ -44,26 +51,26 @@ all: else # !
