I guessed so from the changelog, but how is it fixed ?

He, but your reply are hardly informatives, and also high in the laying blame change, so ... I came to you with a patch i said was hacky, but which allowed me to build the 2.6.15 powerpc kernel, which was good since i pinpiointed the issue, but we needed 5 or so email exchanges and an irc session before we ever came to the conclusion that --arch should not be used for what i tried to use, which is painful. Not entirely your fault, and i guess coming home from a christmas party late at night and trying to work on this didn't help :) > > Nope, and this is the main problem here, that the dpkg-* > > architecture is not the same string as the kernel expect. > > However, what we pass in as --arch is $(architecture) -- which > is not what we pass in to the kernel, which is $(KERNEL_ARCH).

Indeed, and it would have been nice to have exactly this info as the first reply to my report :) > >> No, ARCH is the wrong thing to set here.

Any duplicated code is bad. Well, i would rather have this added code. It is no duplicate, since we don't have this functionality right now though. I suppose i saw using subarches for this as duplicate code though, but i will try to write some creative snipplet to avoid much of that duplication, still in the current powerpc situation, it would be nice to easily have the user override the default in an easy documented way ... > >> --arch is DEB_HOST_ARCH_CPU (or DEB_HOST_GNU_CPU, if that does not > >> exist).

Hence using --arch does the wrong thing. Indeed. As said, i hope you add some more documentation to the --arch option so folk don't make the mistake later on. > >> You are wrong about that. kernel-package _defaults_ to setting > >> kernel ARCH to be the same as DEB_HOST_ARCH_CPU, but does not > >> _assume_ they are the same.

Sure there is, since ARCH migrations are tricky business, i think it is sane to ask users to use the old ARCH for testing purpose and such. > > Ok, i think we should kill ppc.mk and ppc64.mk and work things out > > in powerpc.mk.

Indeed, the exact ay it works may differ some though, but we will see. Friendly, Sven Luther -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
