make-kpkg kernel_headers does not produce arch/x86/include for 3.0 kernels

[Rocko]

Building a 3.0 kernel from kernel.org with the command:

fakeroot make-kpkg --initrd --append-to-version=-generic kernel_image kernel_headers

produces deb packages for linux-image and linux-headers without reporting any errors.

However, the linux-headers package is missing the folder arch/x86/include and its subfolder asm, so modules like nvidia-current will not build using it.

The same command works correctly when building the 2.6.39.3 kernel or earlier.

I have the same bug under Ubuntu 11.04.

[Matthias Lüscher (m-luescher)]

The problem seems to be located in
/usr/share/kernel-package/ruleset/targets/headers.mk:
LINK_ARCH should be set to x86 for 3.0 kernels.

Please note that the kernel package files can be obtained from another location if you add the option "overlay-dir" to make-kpkg. In this case you need to fix the corresponding headers.mk file from the overlay directory.

@lueschem: thanks, that fixes it. I changed the line in headers.mk to

ifeq ($(shell if [ $(VERSION) > 2 ] || [ $(PATCHLEVEL) -eq 6 -a $(SUBLEVEL) -gt 23 ]; then \

and I now have the arch/x86/include folder.

[Nathan Rennie-Waldock (nathan-renniewaldock)]

Thanks, definitely fixes it.

[Alan Orth (aorth)]

I can also confirm this works on Ubuntu 11.04 x86_64 when using `make-kpkg` to make headers packages for Linux kernel 3.0, either statically setting LINK_ARCH=x86, or adding a modified conditional in /usr/share/kernel-package/ruleset/targets/headers.mk.

[Andrei Emeltchenko (andrei-emeltchenko-finik)]

I had the same bug in Ubuntu 11.04 - the Natty Narwhal. Putting LINK_ARCH=x86 to usr/share/kernel-package/ruleset/targets/headers.mk hepled.

[Rocko (rockorequin)]

It is still a problem in kernel-package version 12.036+nmu1 in Oneiric.

[Nathan Rennie-Waldock (nathan-renniewaldock)]

There's a fixed version in my PPA.
