Release 1.12 of kernel build for kernel 2.5 (kbuild 2.5) is available.
http://sourceforge.net/projects/kbuild/, Package kbuild-2.5, download
release 1.12.

This is ready to go to Linus for inclusion in 2.5.[12].  There is one
item on the todo list but it is not a show stopper, the code works as
is.

kbuild 2.5 currently supports i386, ia64, sparc32, sparc64, alpha and
ppc (incomplete).  All are supported on 2.4.16 and 2.4.17, i386 is
supported on 2.5.1.

This announcement is for the base kbuild 2.5 code, i386 against 2.4.16.
Patches for other architectures and kernels will be out later today, it
takes time to generate and test patches for 6 architectures against 3
different kernel trees.  The sooner Linus takes the base patch, the
sooner I will be able to rewrite the core code to speed it up, instead
of spending all my time tracking multiple trees.

http://marc.theaimsgroup.com/?l=linux-kernel&m=99725412902968&w=2
contains information about the base release of kbuild 2.5.

Changelog:

  CML2 changes to handle install formats.

  Add KBUILD_INCLUDE_PATHS for patches that have their own separate
  include tree, including asm-$(ARCH).  selinux does this, I am not
  100% convinced that it is a sensible thing to do but I will support
  it for now.

  Add KBUILD_BASENAME, used when replacing .text.lock with .subsection.

  Documentation corrections by Ghozlane Toumi.

  Move include of arch/$(ARCH)/Makefile.defs.config from global
  makefile to top level.  Needed for PPC.  Have a barf bag ready when
  you read the code in scripts/Makefile-2.5.

  Support include of asm files for other architectures (APUS does this).

  Do not regenerate files on make clean/mrproper.

  Correct bug in $(dir)/$(notdir) with unexpanded variables.

  Handle empty $(arch_head).

  Improve propagation of y/m onto sub-objects.

  As always, Documentation/kbuild/kbuild-2.5.txt is your friend.

TODO:

  Rewrite core code to improve performance.  Not until the existing
  code is in the kernel.

All architecture and tree specific patches for kbuild 2.5 are now
available, if you don't see your arch then nobody has sent me a patch
yet.

kbuild-2.5-2.4.16-3		Base code and i386.  Use this patch for
				2.5.0 as well.
kbuild-2.5-2.4.17-1		From 2.4.16 to 2.4.17.
kbuild-2.5-2.4.18-pre1-1	From 2.4.17 to 2.4.18-pre1.
kbuild-2.5-2.5.1-1		From 2.4.16 (2.5.0) to 2.5.1.
kbuild-2.5-2.5.2-pre3-1		From 2.5.1 to 2.5.2-pre3.

kbuild-2.5-2.4.16-alpha-1	Add on for alpha by Ghozlane Toumi.
kbuild-2.5-2.4.16-ppc-1		Add on for ppc by Tom Rini.
kbuild-2.5-2.4.17-ia64-011226-1	Add on for ia64-011226, only for 2.4.17.
kbuild-2.5-2.4.16-sparc32-2	Add on for sparc32, Ben Collins, Keith Owens.
kbuild-2.5-2.4.16-sparc64-2	Add on for sparc64, Ben Collins, Keith Owens.

Everybody needs kbuild-2.5-2.4.16-3.  Fetch the other patches if you
want other kernels or architectures.

Alpha and PPC do not have CML2 support yet, everything else has CML2
support.  PPC does not have bzImage support yet.

This seems to have been generated (or applied originally) w/ the wrong
-p level (I suspect 'cuz of the wierd way I created the diff tho), since
this creates ./ppc/.., instead of ./arch/ppc/...

And now more importantly, here's a patch to gets everything right.  This
is vs 2.4.16 + kbuild-2.5-2.4.16-3 + kbuild-2.5-2.4.16-ppc-1 (after
making it apply correctly).  I'll be sending along a 2.4.18-pre1 patch
later on (but vs a different base tree for now).  This fixes 3 things:
1) Add -Wa,-m405 to CONFIG_4xx AFLAGS
2) Either include <asm-offsets.h> or "ppc_defs.h".
3) Only have <asm-ppc/processor.h> include <asm/ptrace.h> if we're
!__ASSEMBLY__, since we were getting a warning.  I mean to spend a bit
more time poking around and seeing what/when we should/shouldn't be
defining STACK_FRAME_OVERHEAD, but for now this should do it.

Okay, here's the patch for PPC for 2.4.18-pre1.  I didn't try, but I
suspect that 2.4.17 will work w/o any additional patches.  This patch
relies on 2.4.16-3, 2.4.16-ppc-1, the patch I sent out prior for 2.4.16,
2.4.17-1 and 2.4.18-pre1-1.

Release 1.12.

Updated ppc patches from Tom Rini.  kbuild-2.5-2.4.16-ppc-1 had
incorrect filenames in the patch, it has been replaced with -2.

If you don't see your arch then nobody has sent me a patch yet.

kbuild-2.5-2.4.16-3		Base code and i386.  Use this patch for
				2.5.0 as well.
kbuild-2.5-2.4.17-1		From 2.4.16 to 2.4.17.
kbuild-2.5-2.4.18-pre1-1	From 2.4.17 to 2.4.18-pre1.
kbuild-2.5-2.5.1-1		From 2.4.16 (2.5.0) to 2.5.1.
kbuild-2.5-2.5.2-pre3-1		From 2.5.1 to 2.5.2-pre3.

kbuild-2.5-2.4.16-alpha-1	Add on for alpha by Ghozlane Toumi.
kbuild-2.5-2.4.16-ppc-2		Add on for ppc by Tom Rini.
kbuild-2.5-2.4.18-pre1-ppc-1	ppc changes from 2.4.16 to 2.4.18-pre1.
kbuild-2.5-2.4.17-ia64-011226-1	Add on for ia64-011226, only for 2.4.17.
kbuild-2.5-2.4.16-sparc32-2	Add on for sparc32, Ben Collins, Keith Owens.
kbuild-2.5-2.4.16-sparc64-2	Add on for sparc64, Ben Collins, Keith Owens.

Everybody needs kbuild-2.5-2.4.16-3.  Fetch the other patches if you
want other kernels or architectures.

Alpha and PPC do not have CML2 support yet, everything else has CML2
support.  PPC does not have bzImage support yet.

Is it just me or did 1.12 break i386 in 2.4.18-pre1?
I applied linux-2.4.18-pre1 then:
kbuild-2.5-2.4.16-3                
kbuild-2.5-2.4.17-1
kbuild-2.5-2.4.18-pre1-1
cp /tmp/saved.config /usr/src/linux/.config

I noticed there is no link include/asm to include/asm-i386

Here is my output:
home1:~/linux# ll .config*
  28 -rw-r--r--   1 root     root        25907 Dec 31 00:04 .config

In file included from /usr/include/bits/errno.h:25,
                 from /usr/include/errno.h:36,
                 from /usr/src/linux/scripts/pp_makefile.h:11,
                 from /usr/src/linux/scripts/pp_filetree.c:11:

make: *** [/usr/src/linux/scripts/pp_filetree.o] Error 1
home1:~/linux# cat .tmp_KERNELRELEASE
KERNELRELEASE=2.4.18pre1

Work around is to perform "make oldconfig" then
copy saved.config to /usr/src/linux.  Now
make -f Makefile-2.5 oldconfig works as well as everything
else.

Any thoughts?
Later,
Albert

You have a broken glibc, /usr/include/linux is a symlink to
/usr/src/linux.  Linus has said repeatedly that glibc must not do that,
it gives different results for userspace code depending on which
version of the kernel source you are working on.  The fact that kbuild
2.5 highlights the broken versions of glibc is a bonus.

Newer versions of glibc have local copies of /usr/include/linux which
never change, instead of using a symlink to a random kernel source and
blindly hoping that /usr/src/linux contains something useful.  If you
cannot upgrade glibc, find the version of the kernel that glibc was
compiled against, probably the first kernel your distribution shipped
with.  Install the headers from that kernel as /usr/src/linux to keep
glibc happy.  NEVER change /usr/src/linux again, build your kernels
under a different directory.
