The system:
===========


uname -a
Darwin localhost 7.2.1 Darwin Kernel Version 7.2.1: Wed Jul 14 03:00:02
PDT 2004; root:tmp/xnu-7.2.1-1-root.obj/RELEASE_I386  x86 i386


gcc -v
Reading specs from /usr/libexec/gcc/darwin/i386/3.3/specs
Thread model: posix
gcc version 3.3 20030304 (Apple Computer, Inc. build 1495)



Prerequisites:
==============

# link libmx to libSystem


# this is necessary because some libraries are missing
# from OpenDarwin, in this case the -lmx argument results in:
# /usr/bin/ld: can't locate file for: -lmx
# see http://www.opendarwin.org/bugzilla/show_bug.cgi?id=2194
#
# note: this is just enough to bootstrap the compiler,
# some floating point compiliations might fail

sudo ln -s /usr/lib/libSystem.B.dylib /usr/lib/libmx.dylib

# install new cctools

# according to: http://gcc.gnu.org/ml/gcc/2005-03/msg01149.html
# new cctools are required to build HEAD of gcc
# Since building Apples cctools is somewhat complicated and
# won't work on (Open)Darwin/x86 better use OpenDarwin cctools  
(odcctools)
# see: http://www.opendarwin.org/projects/odcctools/
# and: http://www.opendarwin.org/projects/odcctools/usingodcctools.html

Bootstrapped like:
