Yes the --subarch is available in the kernel-package. Right, but it doesn't
work in the way it should.

* linux-2.2 supports more archs then linux-2.0.  
* alpha, m68k and powerpc have subarchs


So, it should be possible to fetch the (comming) kernel-source-2.2-2.2 
and compiling it in the same way as other debian packages (dpkg-buildpackage -B -rsudo)
and it compiles then all subarchs images on the same platform. 

The kernel-package has the .config files in /usr/lib/kernel-package/Config/config.<subarch>

My current kernel-source/debian/rules is this: 


#!/usr/bin/make -f
#                                            
# debian/rules file for the Debian/GNU Linux kernel-source package
# Copyright 1998 by Hartmut Koptein <koptein@debian.org>

#export DH_VERBOSE=1

package = kernel-source

architecture=$(shell dpkg --print-architecture)

SUBARCH:=


ifeq ($(architecture), alpha)
SUBARCH=?????????????????????????????
endif

ifeq ($(architecture), m68k)
SUBARCH=amiga atari mac
endif

ifeq ($(architecture), powerpc)
SUBARCH=chrp pmac prep
endif

build: 
	/usr/sbin/make-kpkg build --subarch=$(SUBARCH)

clean:
	/usr/sbin/make-kpkg clean
	-rm .config

binary-indep:	
	/usr/sbin/make-kpkg binary-indep

binary-arch:
	/usr/sbin/make-kpkg binary-arch --subarch=$(SUBARCH)

source diff:
	@echo >&2 'source and diff are obsolete - use dpkg-source -b'; false

binary: binary-indep binary-arch
.PHONY: build clean binary-indep binary-arch binary


--------------------------------------

Ok so far. But now the problems:

* make-kpkg --subarch=<arg1> <arg2> <argn>   doesn't work
* make-kpkg --subarch=         (the NULL-argument)  doesn't work
* make-kpkg must put the correct .config file into the kernel-source directory
* for architectures with subarchs we need different debian/control files
* it is not possible to make all images in one run; it is only possible
  to make 
     image1 + modules1 + pack1 with .config1 and debian/control1
     image2 + modules2 + pack2 with .config2 and debian/control2
     ...


Another problem is that linux-2.2 supports more archs but not all. For some
archs we need extra patches. This must be done before building. But make-kpkg
must know this. What about an extra argument --patch for the subarchs
that need this extra patch ?


All this work must be done before linux-2.2 is ready (~15th - 20th December).
(no! not for slink, for potato). For testing kernel-source-2.1.125-2.1.125 is 
available.


Manoj: what about to remove the kernel-package as an extra package and make it
       available into the kernel-source/debian/* directory? This is then the
       kernel-source*.diff.gz (this make some things easier).


 

Tips, hints ....



Thanks,


    Hartmut
