## rpm_runmake

## -----------

## Perform a full build

## This is used within the FF src rpm by the ff_build.sh script

## and for in-place builds its invoked directly by runmake

## When this is invoked, the current directory will be the TL_DIR for

## the source tree of FF

##

## Usage:

##	rpm_runmake [-B 'build_config'] [-n]

##			or

##	rpm_runmake -r [-B 'build_config'] [-C] [-n]

##

## Arguments:

##	-B build_config	release type to build, (debug/release). default is release

##	-r 		rerun the build in place without doing a new checkout/tag

##	-C		don't clobber prior to the rerun

##	-n		No build.  Useful for checking build machine

##

## In addition, the following environment variables are expected to be set:

##	RELEASE_TAG, BRANCH_TAG, BUILD_TARGET, PRODUCT, RELEASE_HOME, BUILD_CONFIG 

##	The target command is expected to have already been run to set up the

##	environment for the specified target

##

##	re-run can be used for 2 situations:

##	1. re-run a failed build to correct incorrect weeklybuild arguments

##		or other non-source code related problems (out of disk space)

##	2. re-run a build for a different BUILD_TARGET_OS_VERSION while using the same

##		source code image/tag

##	If the source code needs to be corrected, a full weeklybuild should be run

##	after the correction such that the code is properly tagged.

##

##	Since weeklybuild and target commands always set BUILD_CONFIG, this

##	script ignores BUILD_CONFIG.  As such the BuildOptions file

##	or the -B argument completely control BUILD_CONFIG for this product.

# A given release will be targeted for a specific version of ofed

# however we allow build.config to override if needed

export OFED_STACK_PREFIX=${OFED_STACK_PREFIX:-/usr}
