successful bootstrap/install of gcc-4.0-20040912 on OpenDarwin 7.2.1/x86 (i686-apple-darwin7.2.1)

[Lars Sonchocky-Helldorf]

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-patches/2004-08/msg00104.html 
# newer cctools are needed 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

ftp http://www.opendarwin.org/downloads/odcctools-20040906.tar.bz2
tar -jxf odcctools-20040906.tar.bz2
mkdir odcctools-build
cd odcctools-build/
../odcctools-20040906/configure --prefix=/usr
make
sudo make install
cd ..


Bootstrapped like:
==================

# bootstrap the compiler

# note: those STAGE1_CFLAGS are needed to avoid
# http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14780

ftp 
ftp://gcc.gnu.org/pub/gcc/snapshots/4.0-20040912/gcc-4.0-20040912.tar.bz2
openssl md5 gcc-4.0-20040912.tar.bz2
tar -jxf gcc-4.0-20040912.tar.bz2
mkdir gcc-build
cd gcc-build/
../gcc-4.0-20040912/configure --prefix=/tmp/gcc
make bootstrap STAGE1_CFLAGS="-no-cpp-precomp -Wa,-force_cpusubtype_ALL"
sudo make install
cd ..


Result of bootstrap:
====================

/tmp/gcc/bin/gcc -v
Reading specs from 
/private/tmp/gcc/bin/../lib/gcc/i686-apple-darwin7.2.1/4.0.0/specs
Configured with: ../gcc-4.0-20040912/configure --prefix=/tmp/gcc
Thread model: posix
gcc version 4.0.0 20040912 (experimental)

I am currently testing the result with make -k check in my build directory 
and will post the results later.
