I needed more serial ports that the basic CentOS Version 4 system is built to use so I'm using the following kernel build instructions to build the new 2.6 kernel: http://www.hylafax.org/content/Handbook:Basic_Server_Configuration:Modem-speci fic_Guidance
I disagree with a fair amount of their method.
I believe the procedure is correct but the kernel is not building.
Because the procedure isn't really correct.
I used the "kernel-2.6.9-34.EL.src.rpm file that I found on one of the CentOS mirrors.
You should get the source from the most updated kernel so you're running code that doesn't have known holes. http://mirror.centos.org/centos-4/4/updates/SRPMS/
Here are the problems that I've had so far. 1) The correct architecture to use. Does anyone know which architecture should be used for the Dell 2650 Dual Xeon processor? I thought the correct configuration file would have been "kernel-2.6.9-i686-smp.config". I've also tried "kernel-2.6.9-i586-smp.config" and run into the same problems.
probably i686(smp) however newer xeons(EM64T) are also x86_64(smp) capable. Up to you to figure out which one you have and match your distro accordingly. Safe money says i686.
2) When it built the rpm it was named "kernel-2.6.934.ELcustom-1.i386.rpm" but I would have expected it to be named "kernel-2.6.9-34.ELcustom-1.i386.rpm". Was it build using the correct name or might something be misconfigured.
Sounds like you edited the '%define release' statement in the spec file.
3) When I entered the following command: "rpm -i /usr/src/redhat/RPMS/i386/kernel-2.6.934.ELcustom-1.i386.rpm" I get the following error: "error: Failed dependencies: kernel >= 2.6.10 conflicts with lksctp-tools-1.0.2-6.4E.1.i386"
yes, 934 is greater than 10, so this is to be expected :-P
The "kernel >= 2.6.10" does not make sense but I was wondering if it had anything to do with the file being named kernel-2.6.934.... or is there some other problem I should be looking for?
Nope that's the money right there. What you should do. (Rough steps, but close enough) Prerequirement http://www.rpm.org/hintskinks/buildtree/ 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. 1. Get the kernel source rpm from the url above. and make sure you have all the deps installed. 2. cd to buildroot/SPECS, and do 'rpmbuild -bp kernel.spec' This will create and patch the kernel tree. 3. Copy the buildroot/SOURCES/kernel-2.6.9-i686-smp.config to buildroot/BUILD/kernel/linux-version/.config 4. Configure your kernel how you see fit. make menuconfig etc. 5. Copy the .config back to buildroot/SOURCES/kernel-2.6.9-i686-smp.config 6. run rpmbuild --target=i686 -bs buildroot/SPECS/kernel.spec 7. 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.
