build.sh

#!/bin/sh 

# Build CMUCL from source.  The intent of this script is to make it a
# little easier invoke the other scripts and build CMUCL.  In the
# simplest case where your lisp is named cmulisp and no special
# bootfiles are needed, you would build CMUCL using:
#
#    src/tools/build.sh -C ""
#
# This will create a set of directories named build-2, build-3, and
# build-4 and CMUCL will be built 3 consecutive times, using the
# version of CMUCL from the previous build.
#
#
# You can control which of the builds are done by using the -1, -2, -3
# options, but it is up to you to make sure the previous builds exist.
#
# A more realistic example would be
#
#    src/tools/build.sh -v "My build" -B boot-19b.lisp -o "my-lisp -noinit"
#
# where you need to load the bootfile boot-19b.lisp and your lisp is
# not named cmulisp, but my-lisp.
#
# For more complicated builds, you will need to run create-target.sh
# manually, and adjust the bootstrap or setenv files by hand.  Once
# this is done, you can run build.sh to build everything.  Just be
# sure to leave off the -C option.
#
# Cross compiling is not supported with this script.  You will have to
# do that by hand.
#
# For more information see src/BUILDING.
