[PATCH 1/1] deb-pkg: fix cross-compile build

[Nuno Subtil]

When generating the header package, scripts/package/builddeb was inferring the
target architecture by looking at the output of dpkg --print-architecture. This
allows KBUILD_DEBARCH to override that.

Greetings,

Compile breaks when using the following command:
    fakeroot make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- deb-pkg

With 'set -x' in scripts/package/builddeb, the relevant output is:
    + '[' -n '' ']'
    ++ dpkg --print-architecture
    + arch=i386
This indicates that KBUILD_DEBARCH is not set.

The debian/control file is written with the following section:
    Package: linux-headers-2.6.39-rc5+
    Provides: linux-headers, linux-headers-2.6
    Architecture: i386
    Description: Linux kernel headers for 2.6.39-rc5+ on i386
     This package provides kernel header files for 2.6.39-rc5+ on i386

This produces the following error output:
    + forcearch=-DArchitecture=armel
    + dpkg-gencontrol -isp -DArchitecture=armel
-plinux-headers-2.6.39-rc5+ -P/opt/kernel-linus/linux-2.6/debian/hdrtmp
    dpkg-gencontrol: error: current host architecture 'armel' does not
appear in package's architecture list (i386)

Regards,
Robert

Re: [PATCH 1/1] deb-pkg: fix cross-compile build

[Nuno Subtil]

This patch is not meant to fix that case, only the case where
KBUILD_DEBARCH is used.

KBUILD_DEBARCH seems to be meant to be used as an override for what
Debian wants to see as the target architecture. Arguably, the right
thing to do here might be to do the same arch detection sequence
that's done in create_package(), which looks at UTS_MACHINE first and
the KBUILD_DEBARCH override after that (though I'm not entirely sure).

This patch only adds the KBUILD_DEBARCH override, but that is still
better than the current situation. I can easily get the rest in later
if needed.

[PATCH 1/1] deb-pkg: fix cross-compile build

[Nuno Subtil]

When generating the header package, scripts/package/builddeb was inferring the
target architecture by looking at the output of dpkg --print-architecture. This
makes it go instead through the same detection sequence that was previously
implemented in create_package.

Re: [PATCH 1/1] deb-pkg: fix cross-compile build

[Nuno Subtil]

It looks like your patch duplicates the arch detection logic that's
already in create_package, except not completely. I think this is not
desirable.

I modified your patch to isolate this logic into a separate function
and respect the KBUILD_DEBARCH override (which mostly means I moved
the original logic into a separate function). This should make your
case work as well, besides respecting the KBUILD_DEBARCH override.

Maks, Michal, can you please take a look at this new patch?

Thanks,
Nuno

I have tested this patch.  It builds fine for arm with the following
command:
fakeroot make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- deb-pkg

However x86_64 fails (when using an i386 machine).
fakeroot make ARCH=x86_64 deb-pkg

The error occurs in scripts/package/builddeb
+ forcearch=-DArchitecture=amd64
+ dpkg-gencontrol -isp -DArchitecture=amd64 -plinux-headers-2.6.39-rc7+
-P/opt/kernel-linus/linux-2.6/debian/hdrtmp
dpkg-gencontrol: error: current host architecture 'i386' does not appear
in package's architecture list (amd64)

The debian/control file is as follows:

The debian/control file for an unpatched scripts/package/builddeb would
assign 'i386' instead of 'amd64'.

That seems wrong to me. Were the resulting packages actually usable on amd64?

I modeled my patch after behavior I saw in the unpatched script.  I had 
also originally set x86_64 to amd64 with the exact results I get with 
your patch.  So, I looked at what the unpatched kernel was doing, which 
is putting i386 in those fields when building for x86_64 on an i386 
machine.  I don't know the results would actually run because I don't 
have an x86_64 myself.  It may not run, but it does build.

cheers!
