Hi All, I am using CentOs 4.2 . I need to change the kernel rpm . I downloaded the kernel-2.6.9.EL .src.rpm. after installing this rpm i changed the linux-2.6.9.tar.gz . Bu changing the source i made the rpm. But gives the error . Is it anyother file also required?? . Can anyone knows how i can do this ?
I generally don't recommend rebuilding the kernel, but from the sounds of things, you didn't apply the patches from the src.rpm. There are a couple hundred of them that you should apply. The easy way to do this is to use the rpm-build utilities to prep the source for you.
rpm -ivh kernel-2.6.9-34.src.rpm cd $BUILDROOT/SPECS/ (wherever your buildroot is defined, don't build as root.) rpmbuild -bp kernel.spec --target=i686 (or x86_64) cd ../BUILD/kernel-2.6.9/ and there's your patched default kernel set.
I've managed to cut most of the meat out of these instructions, so some things you'll have to figure for yourself like setting up an rpm build root etc, or wait for other people to reply with all the info, or links to the real documentation. This should point you in the right direction though. I'd also recommend that you take the config from /boot/ or from the kernel source and modify it to your needs rather than doing a completely new config on your own.
And as the last pointer, if you're doing this for XFS support, or for added hardware support, check out the unsupported kernel in centosplus. We already have a rebuilt kernel with support for more things that the stock rhel rebuilt kernel.
