<snip>
What you should do. (Rough steps, but close enough)
Prerequirement http://www.rpm.org/hintskinks/buildtree/
Done, I setup the user buildcentos and created the tree under that users home directory.
There are loads of people saying 'do not build as root'. There's good reason for this, so either create a user to build as or use your own, so long as you're not building as root.
- Get the kernel source rpm from the url above. and make sure you
have all the deps installed.
Done!
- cd to buildroot/SPECS, and do 'rpmbuild -bp kernel.spec' This will
create and patch the kernel tree.
- Copy the buildroot/SOURCES/kernel-2.6.9-i686-smp.config to
buildroot/BUILD/kernel/linux-version/.config
Done.
- Configure your kernel how you see fit. make menuconfig etc.
Here is where I'm having problems. The make menuconfig fails:
[buildcentos@quark linux-2.6.9]$ pwd /home/buildcentos/rpmbuild/BUILD/linux-2.6.9 [buildcentos@quark linux-2.6.9]$ ls -al total 72 drwxrwxr-x 2 buildcentos buildcentos 4096 Jul 19 17:15 . drwxrwxr-x 3 buildcentos buildcentos 4096 Jul 19 17:14 .. -rw-rw-r-- 1 buildcentos buildcentos 60982 Jul 19 17:18 .config [buildcentos@quark linux-2.6.9]$ make menuconfig make: *** No rule to make target `menuconfig'. Stop.
At this point I'm stuck. I've done the menuconfig before using the other procedure but no joy this time. I searched the entire directory tree but can not find a makeconfig file.
- Copy the .config back to
buildroot/SOURCES/kernel-2.6.9-i686-smp.config
- run rpmbuild --target=i686 -bs buildroot/SPECS/kernel.spec
- run rpmbuild --rebuild --target=i686
buildroot/SRPMS/kernel-version.src.rpm
This will build a kernel of the same version and release with your new options. I'd recommend incrementing the release value defined in the line I mentioned earlier.
These are rough steps, but should point you in the right direction.
