recompiling new kernel in fedora 3

x2aws · 11-21-2004, 09:27 AM

Does anyone know the steps to recompile a new kernel in fedora core 3?? I want to replace the 2.6.9.XXX kernel with the new 2.6.10-rc3 kernel. I follow my usual steps, edit the grub to find the new kernel, system.map, initrd, etc. but at reboot it gives me a error 15, file not found? Any suggestions??

Thanks!!

Did you got correct stuff in /etc/grub.conf? On FCx and RHEL you can use make install to do after all kernel compilation.

I looked at grub.conf and noticed how the file was setup. I cp the files right out of /usr/src/linux/xxxx over to boot, and renamed them to reflect the kernel i was using, eg. vmlinux.2.6.9.10-rc3, etc. I followed the way fedora had grub looking and just copied it. Unlike Suse, where it just uses System.map, vmlinux, etc, my copy of fedora 3 uses System.map.2.6.9.xxx, and vmlinux.2.6.9.xxx. Should i just scratch the endings and have it just use the basics?? Let me know!!

Thanks!!

Do 'make install' will take care the grub.conf too.. you do not need to modify your grub.conf manually.

So basically, just do my make menuconfig, then make (which should take care of modules and modules_install), then make install and that should be it?? when i reboot, it should start up with the 2.6.10-rc3 kernel?? when i do reboot, how do i know what version of the kernel i am running?? is there a simple command line to type??

I usually do the following when compiling a new kernel

# make oldconfig
# make menuconfig (if needed)
# make
# make modules_install
# make install

During the reboot, I will choose the new kernel that I've just compiled from GRUB menu.

and if u're not sure which kernel u're using, just use uname -r and it'll display your kernel version

Just a question - I have no problem compiling kernels, I do it often on other distros, but where is the kernel source on Fedora Core 3? I want to recompile my kernel, but there is no source anywhere on my box, and I cant even seem to find the source rpm online.

I believe it's on one of the CD's.

But don't spend time on searching it, go to www.kernel.org and download the recent one.

I did what everyone said, and it still wants to boot to the default 2.6.9 kernel. I need the 2.6.10 for the latest DVB drivers. When i read the grub conf file, it still shows the link to the vmlinuz-2.6.9.xxx file, nto the new one i just recompiled. Any more help??

Thanks!!

$ locate grub.conf
/boot/grub/grub.conf
/etc/grub.conf

Make sure you are editing the right one.

x2aws · 11-22-2004, 05:09 PM

I got the right one. when i edit it, it always comes up with a error 15:file not found when i reboot. any other suggestions?? Thed default kernel boots just fine.

I really don't have your answer however perhaps this info means more to you than me

cp arch/i386/boot/bzImage /boot/vmlinux-2.6.x
cp System.map /boot/System.map-2.6.x

sorry if really means nothing to you got it from kernelnewbies.org
