For the time-being, you can bootstrap with --disable-multilib.
The real solution requires Apple to provide an updated cctools with a
working ld64.
Hi,
FWIW, the 20060415 mainline (4.2) snapshot bootstrapped for me, using
odcctools-20060413 (odcctools-590.36od13). This machine is a dual G5
(ppc970) using OS X 10.3.9, and Apple's gcc-3.3 (build 1640).
However, before building, I patched the following 2 files:
In gcc/config/darwin.h:
at: #define LINK_COMMAND_SPEC :
replace:/usr/bin/libtool
with: /path/to/odcctools/bin/libtool
In libstdc++-v3/scripts/make_exports.pl (for OS X 10.3 only):
replace:nm -P
with: /path/to/odcctools/bin/nm -P
(probably not necessary if this nm is already found first in path)
Configure command (your paths may vary):
../configure --prefix=/Users/fang/local/gcc-4.2 \
--program-suffix=-4.2 \
--disable-nls \
--with-gmp=/sw \
--with-mpfr=/sw \
--infodir='${prefix}/share/info' \
--with-included-gettext \
--host=powerpc-apple-darwin`uname -r|cut -f1 -d.` \
`if test ! -f /usr/lib/libSystemStubs.a ; then echo -n "--
with-as=/Users/fang/lib/odcctools/bin/as --with-ld=/Users/fang/lib/
odcctools/bin/ld" ; fi`
I just tried to follow your detailed instructions (thanks) and
bootstrap still failed with today's mainline. I installed
odcctools-20060413, changed
[lindv2:mainline/gcc/config] lucier% rcsdiff darwin.h

RCS file: RCS/darwin.h,v
retrieving revision 1.1

and my configure and build command was
[lindv2:gcc/mainline/objdir64] lucier% cat ../build-gcc-64
#!/bin/tcsh
/bin/rm -rf *; ../configure --with-as=/usr/local/odcctools-20060413/

I have

Can you see what I'm doing incorrectly here?
