# APPLE LOCAL file build machinery
# Apple GCC Compiler Makefile for use by buildit.  
#
# This makefile is intended only for use with B&I buildit. For "normal"
# builds use the conventional FSF top-level makefile.
#
# Usage:
#
#  1. Set BUILDIT_DIR to where you want the build to go.  Buildit uses
#     this to set up DSTROOT, OBJROOT, etc.
#
#     examples: 
#       export BUILDIT_DIR=/tmp/build_goes_here   [sh or bash]
#       setenv BUILDIT_DIR /tmp/build_goes_here   [csh or tcsh]
#
#  2. Run buildit.  Here's a brief general description generated by
#     running buildit --help (reformatted to fit in here):
#
#     Usage: buildit projectSourceDirectory [build options] \
#                    [-- other arguments]
#
#     Mandatory argument:
#       projectSourceDirectory      The root directory of project source
#                                   tree (can be absolute or relative
#                                   path to the project source tree)
#
#     Build options:
#       -release                    Use RC_CFLAGS (compiler flags) from
#                                   specified release (use release name
#                                   like Cheetah, Puma, Jaguar, ...)
#       -arch <archName>            Build with specified architectures(s)
#                                   (-arch can be multiply specified:
#                                    -arch ppc -arch i386)
#                                   (default is native architecture)
#       -noclean                    Disables deletion of {OBJ,SYM,DST}ROOT
#                                   before start of build
#       -noinstall                  Disables invocation of 'install' target
#       -noinstallhdrs              Disables invocation of 'installhdrs' target
#       -noinstallsrc               Disables invocation of 'installsrc' target
#       -noverify                   Disables verification of project DSTROOT
#                                   after build
#       -nosum                      Disables before-and-after checksumming
#                                   of project source
#       -noprebind                  Disables prebinding
#       -noperms                    Disables permissions setting on DSTROOT
#                                   after build
#       -merge <mergeDir>           Merges resulting DSTROOT into "mergeDir"
#       -target <buildTarget>       Specifies an alternate Make or Jam build
#                                   target (instead of "install")
#       -othercflags <cflags>       Specified cflags are appended to RC_CFLAGS
#                                   for build
#
#     Other arguments:
#       Other arguments can be passed to the makefile by putting them
#       at the end of the buildit argument list following a double dash ("--").
#      Arguments that contain whitespace should be enclosed in quotes.
#
#     examples: (assume $gcc3 is shell variable with gcc3 dir in it)
#
#       Creating a new root:
#         mkdir /tmp/my-build
#         cd /tmp/my-build
#         export BUILDIT_DIR=`pwd`
#         ~rc/bin/buildit -noverify -nosum -noinstallsrc -noinstallhdrs \
#                         -arch ppc -arch i386 $gcc3 BOOTSTRAP=
#
#       Rebuilding the previous root (assumes BUILDIT_DIR unchanged):
#         ~rc/bin/buildit -noverify -nosum -noinstallsrc -noinstallhdrs \
#                         -noclean -arch ppc -arch i386 $gcc3
#
# You can specify BOOTSTRAP= to stop the normal bootstapping of the
# compiler during it's build.
#
# You can specify TARGETS=ppc (or i386) to limit the build to just one
# target.  The default is for ppc and i386.
