[kbuild-devel] [Fwd: Kbuild 2.5-2.2 for SuperH]

[Greg Banks]

G'day,

Here's the SuperH patches for kbuild-2.5 upgraded to 2.2 (kernel 2.5.10).

There's no functional change except that 2.5.10 is slightly less broken
than 2.5.8 so the "hacks" patch is smaller.

I just noticed that 2.3 is out...<sigh> if I'd started an hour earlier
perhaps this message wouldn't be obsolete at posting.  Anyway I'll
update SuperH to 2.3 on Friday.

Greg.

KBuild-2.5 for the SuperH Linux port
====================================

Here's how to build a LinuxSH kernel using kbuild-2.5.

Ingredients
-----------

linux-2.5.10.tar.bz2                Linus tarball from ftp.kernel.org

linuxsh-2.5.10.tar.bz2/             LinuxSH tarball from linuxsh.sf.net

kbuild-2.5-core-8.bz2               KBuild 2.5 core patch from kbuild.sf.net

kbuild-2.5-common-2.5.10-2.bz2      KBuild 2.5 common patch from kbuild.sf.net

kbuild-2.5-sh-2.5.10-1gnb.bz2       KBuild SuperH patch, from here

kbuild-2.5-shcommon-2.5.10-1gnb.bz2 KBuild common intersection with SuperH
                                    patch, from here

kbuild-2.5-hacks-2.5.10-1gnb.bz2    Hacks so 2.5.10 compiles, from here



Procedure
---------

1.  Extract linux-2.5.10.tar.bz2 into a directory linux-2.5.10

2.  Apply patches to linux-2.5.10 (the order matters)

    * kbuild-2.5-core-8.bz2
    * kbuild-2.5-common-2.5.10-2.bz2
    * kbuild-2.5-sh-2.5.10-1gnb.bz2
    * kbuild-2.5-shcommon-2.5.10-1gnb.bz2
    * kbuild-2.5-hacks-2.5.10-1gnb.bz2
    
3.  Checkout (or extract) linuxsh-2.5.10

4.  Make the directory where all the build output will go

    mkdir obj
    
5.  Setup environment variables (in bash syntax).  Note that the
    full pathnames and trailing /s are significant.

    export KBUILD_SRCTREE_000=$PWD/linux-2.5.10/
    export KBUILD_SRCTREE_001=$PWD/linuxsh-2.5.10/
    export KBUILD_OBJTREE=$PWD/obj/

6.  Copy your .config into $KBUILD_OBJTREE and

    make \
        -f $KBUILD_SRCTREE_000/Makefile-2.5 \
        ARCH=sh CROSS_COMPILE=sh-unknown-linux-gnu- \
        oldconfig

7.  Do the actual build

    make \
        -f $KBUILD_SRCTREE_000/Makefile-2.5 \
        ARCH=sh CROSS_COMPILE=sh-unknown-linux-gnu- \
        installable

8.  Install the results

    make \
        -f $KBUILD_SRCTREE_000/Makefile-2.5 \
        ARCH=sh CROSS_COMPILE=sh-unknown-linux-gnu- \
        install
