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/sandburst/karef/Makefile | 19 ++++++++++++++----- board/sandburst/metrobox/Makefile | 19 ++++++++++++++----- 2 files changed, 28 insertions(+), 10 deletions(-) (limited to 'board/sandburst') diff --git a/board/sandburst/karef/Makefile b/board/sandburst/karef/Makefile index 8b3173c..60d5573 100644 --- a/board/sandburst/karef/Makefile +++ b/board/sandburst/karef/Makefile @@ -1,4 +1,7 @@ # +# (C) Copyright 2006 +# Wolfgang Denk, DENX Software Engineering, wd@denx.de. +# # (C) Copyright 2005 # Sandburst Corporation # Travis B.
