# Usage:
#	FullTest.sh <full path to kaffe source> [prefix]
# The [prefix] argument is optional, defaults to the last element
# of the full path.
#
# Build/test/install a full complement of Kaffe variations.  Stores
# full log of the build/test/install.  Prints a summary of steps and
# any failures to stdout.  The commands are all run under 'nice' so
# your machine should still be usable while you run this script.
#
# BEFORE RUNNING: Edit the BASE_OBJ_DIR and BASE_INSTALL_DIR
# variables.  Set them to someplace sensible on your system.  Edit
# GMAKE if necessary to point to GNU make (or drop the MAKE_OPTS?).
# To add a new build combination, give it a name in the BUILDS line,
# and then below in the case statement that interprets the names, set
# the configuration you'd like to test.
#
# TODO:
#

# About 350Mb of object trees
BASE_OBJ_DIR=/home/pat/kaffe-core/obj

# About 70Mb of installed stuff 
BASE_INSTALL_DIR=/home/pat/kaffe-core/install

GMAKE=${GMAKE:-make}
# -s means quiet; -j for multiple jobs
