u-boot.git/rules.mk, branch v2009.08-rc2 Unnamed repository; edit this file 'description' to name the repository. unify HOST_CFLAGS and HOSTCFLAGS 2009-07-23T19:26:14+00:00 Mike Frysinger vapier@gentoo.org 2009-07-19T19:17:03+00:00 9aef73888509d10193615ee5cd9cf439ca44e937 The top build system sets up HOSTCFLAGS a bit and exports it, but other places use HOST_CFLAGS instead. Unify the two as HOSTCFLAGS so that the values stay in sync. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Add support for a saving build objects in a separate directory. 2006-09-01T17:49:50+00:00 Marian Balakowicz m8@semihalf.com 2006-09-01T17:49:50+00:00 f93286397ed2a7084efb0362a43ee09f11702349 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. 
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.
