2013-06-24kbuild: fix error when building from src rpmMike Marciniszyn
The following issue can be reproduced with Linus' tree on an x86_64 server. >+ cp /home/user/rpmbuild-test/BUILDROOT/kernel-3.9.2.x86_64/boot/vmlinuz-3.9.2 >cp: missing destination file operand after >/home/user/rpmbuild-test/BUILDROOT/kernel-3.9.2-1.x86_64/boot/vmlinuz-3.9.2' >Try `cp --help' for more information. >error: Bad exit status from /var/tmp/rpm-tmp.R4o0iI (%install) Here are the commands to reproduce: make defconfig make rpm-pkg Use the resulting src rpm to build as follows: mkdir ~/rpmbuild-test cd ~/rpmbuild-test rpmbuild --rebuild --define "_topdir `pwd`" -vv ~/rpmbuild/SRPMS/kernel-3.10.0_rc1+-1.src.rpm The issue is because the %install script uses $KBUILD_IMAGE and it hasn't been set since it is only available in the kbuild system and not in the %install script. This patch adds a Makefile target to emit the image_name that can be used and modifies the mkspec to use the dynamic name in %install.

Commit 6501320311664e11ad5489fedb17ea1f817c2617 dropped the rpm spec as a prerequisite for the binrpm-pkg target but forgot to update $< usage, which causes the rule to break.

2013-04-18rpm-pkg: Always regenerate the specfileMichal Marek
The *pkg targets are always run, so it makes no sense to cache the generated specfile. This also fixes build errors when the specfile becomes out of date, without the Makefile noticing it: $ make rpm works $ echo yadadada >localversion-test $ make rpm fails, because kernel.spec assumes the old kernel release string Signed-off-by: Michal Marek <mmarek@suse.cz>
2013-04-18rpm-pkg: Do not write to the parent directoryMichal Marek
Now that we only package explicitly listed files to the tarball, there is no need to abuse the parent directory. Signed-off-by: Michal Marek <mmarek@suse.cz>
2013-04-18rpm-pkg: Do not package the whole source directoryMichal Marek
The source tree can contain lots of uninteresting data like tag or cscope files, packaging which slows down make rpm needlessly. It can also break the build, if the tree contains an unrelated file named *.spec. The downside of this change is that new subdirectories have to be added to the KBUILD_ALLDIRS variable in the top-level Makefile. The upside is that the behavior is more predictable.

2013-04-08buildtar: Add ARCH to the archive nameBorislav Petkov
When dealing with multiple sub-arches (like 32- and 64-bit on x86, for example) generating a bunch of kernel tar archives with the same name but for different sub-arches could get confusing and error-prone. Also, the build process could overwrite otherwise unrelated builds and you probably don't want that. So, add the architecture to the archive name for more clarity and less shoot-yourself-in-the-foot practices. Signed-off-by: Borislav Petkov <bp@suse.de> Signed-off-by: Michal Marek <mmarek@suse.cz>

2013-02-22kbuild: clear KBUILD_SRC when calling 'make' in RPM specDavid R. Bild
'make rpm-pkg' and 'make binrpm-pkg' fail when the kernel source is read-only. Specifically, when the RPM spec generated by scripts/package/mkspec is run, KBUILD_SRC happens to be set to the source location and thus the invocation of 'make headers_install' fails when an internal call to 'filechk' tries to write a file into the source tree. The fix is to clear KBUILD_SRC for the 'make headers_install' invocation in the spec file, as is already done for the 'make modules_install' invocation. Signed-off-by: David R.

2012-09-27Kbuild: use normal compression settings for tar*-pkgAndi Kleen
For large kernel configurations (like a distribution kernel) targz-pkg takes a quite long time to just do the compression. I clocked it at 15+mins for a SUSE kernel like config on a fast system. And tarxz and bzip2 are even slower. The main reason is that the script that is doing the taring sets the highest compression level (-9). When I change it to just use the defaults the gzip time for the same kernel goes down to ~3 mins. I haven't tested xz and bzip, but I expect those to be much faster too. I'm not willing to wait that long for a small compression gain. So just change the script to use the defaults.

Instead of creating the debian package for the compiling userland, create it for a userland matching the kernel thats being compiled. This patch supports all Lenny release architectures, and Linux-based architecture candidates for Squeeze. If it can't find a proper Debian userspace it displays a warning, and fallback to let deb-gencontrol use the host's userspace arch. Eg. with this patch the following make command: make ARCH=i386 deb-pkg will output an i386 Debian package instead of an amd64 one, when run on an amd64 machine.
