This is the same issue as the follow patch tries to solve:

So it is not just PPC-darwin.

If you start with a 32-bit compiler, the correct sequence of operations is:

CC="gcc -m64" $srcdir/configure --prefix=/pkgs/gcc-4.1.0 --with-gmp=/sw/
--with-mpfr=/sw/ --with-as=/usr/local/odcctools-20060123/bin/as

Actually this is talked about in the thread I pointed to, since the addition of
toplevel bootstrap, GCC should be able to do this without any troubles.

Well, you'd probably also need to pass powerpc64-apple-darwin8.5.0 to
configure.

Note that the PR is reported against 4.1.0.  And this works flawlessly on
SPARC.

Actually, I want the compiler to generate 32-bit binaries by default,  
and your earlier instructions work well.

I just want cc1 to be compiled with -m64 so that it can allocate  
2.4GB of storage when it's compiling some computer-generated C files.  
(I don't really think it should take 17 minutes and 2.4GB of storage  
to compile a 6.5MB .i file.)

By the way, the last thing the bootstrap does is build libiberty  
again with BOOT_CFLAGS; it would seem reasonable to me to build it  
earlier with BOOT_CFLAGS, so I don't have to build the stage1  
compiler with CC='gcc -m64'

Geoff,

r117741, however I am still seeing a failure when building without
--disable-multilib on a G4...

If you meant to cross compile, use `--host'.

This is with the 20061024 gcc 4.2 snapshot using Xcode 2.4 and the matching
odcctools
release from Xcode 2.4. No such problems on a G5.

Geoff,
     To clarify my previous remarks, it appears that this configure failure
happens in
libgfortran so it maybe that the changes in r117741 needs to extended to
include
libgfortran. The build is in stage3 when the configure failure occurs of
course.

This is also exactly what I see happening on a G4 build of the same 4.2
snapshot.  It tries to build a multilib for fortran.

Running...

aclocal

...in libgfortran is insufficient to solve the multilib problem. The resulting
conflg.log from the resulting build in the libgfortran directory is attached to

The use of...

cd gfortran
aclocal -I ../config
autoconf

eliminated the build problems on a G4 for libgfortran. However it moved the
problems on to boehm-gc. I suspect we need to regenerate the aclocal.m4 and
configure for the libgfortran, boehm-gc, libffi and libjava subdirectories.

Perhaps other directories need regen., according to Mike, the following are
outdated (as of 4.2-20061024):

http://gcc.gnu.org/ml/gcc/2006-10/msg00578.html

libdecnumber/aclocal.m4
zlib/aclocal.m4

libmudflap/configure
libmudflap/aclocal.m4
boehm-gc/configure
boehm-gc/aclocal.m4
libffi/aclocal.m4
libjava/configure

BTW, this report is against 4.1, but we've been discussing 4.2.  Should this be
addressed in a new report?

I can now complete  a multilib build of the languages c, c++, objc and fortran

------- Comment #16 from howarth at nitro dot med dot uc dot edu  2006-11-03 03:36 -------
After patching configure.ac and regenerating configure in zlib with...

aclocal -I ../config
autoreconf -I ../config

I find that I don't get a zlib subdirectory in the powerpc-apple-darwin8  build
directory anymore. I am assuming that the patch has freed the gcc build to use
the system zlib instead. Interestingly, if I compare what I see on i386 linux,
I don't see a zlib build subdirectory created for a stock gcc 4.2 build there.
However if I look at a build on x86_64, I see a zlib build subdirectory which
suggests I may have fixed a bug in the build of zlib on multilib systems with
this zlib patch.

That means as was not found in the first place.

>--target=powerpc-apple-darwin9.6.0 

Since build == host != target, you are building a cross compiler and not a
native compiler so this will never work correctly the way you are building.

So, to get back to basics, how do I build a compiler on darwin that has a
64-bit gcc/cc1/etc., but compiles to 32-bit binaries by default?
