Subject: gcc4 compile fixes
Date: Fri, 18 Mar 2005 16:55:43 -0800 [thread overview]
Message-ID: <423B788F.7040705@kegel.com> (raw)
Howdy all. I'm trying to bring up gcc-4.0 toolchains
using the headers from linux-2.6.11.3, and as a sanity
check, I'm trying to build ppc750 and ppc970 kernels, too.
I'm finding things here and there that need patching to let
the build finish. For instance:
In file included from include/asm/setup.h:8,
from include/asm/machdep.h:8,
from include/asm/irq.h:6,
from include/asm/hardirq.h:8,
from include/linux/hardirq.h:6,
from include/asm-generic/local.h:6,
from include/asm/local.h:4,
from include/linux/module.h:21,
from init/main.c:16:
include/asm-m68k/setup.h:365: error: array type has incomplete element type
(This pops up because asm-ppc/setup.h just includes asm-m68k/setup.h.)
That's a garden-variety 'used before defined' problem, fixed thus:

If somebody else has already fixed all of these, I'd rather
just use their sources. So... shall I keep on patching
and posting, or are these already fixed somewhere?
Thanks,
Dan
