I'm building the kernel (3.5) from /media/src_prog/linux-3.5/ to /media/sda5_k/. I've gone through the following steps:

make O=/media/sda5_k/ menuconfig
make -j2 O=/media/sda5_k/
make O=/media/sda5_k/ modules_install

And when it comes to make O=/media/sda5_k/ install all I get is:

[root@localhost linux-3.5]# make O=/media/sda5_k/ install
sh /media/src_prog/linux-3.5/arch/x86/boot/install.sh 3.5.0 arch/x86/boot/bzImage \
    System.map "/boot"
Cannot find LILO.
[root@localhost linux-3.5]#

I also tried this manually:

cp /media/sda5_k/arch/x86/bzImage /media/sda5_k/boot/
cp /media/sda5_k/arch/x86/System.map /media/sda5_k/boot/

and repeated the make O=/media/sda5_k/ install but it doesn't work.

I'm using Arch for compilation and boot process is done with Ubuntu's GRUB2.

What do I do at this step?

/dev/sda1/boot -> Boot (Ubuntu's) the one bound to MBR.

I haven't checked whether this still applies to 3.5, but I think the kernel makefiles only support Lilo, not Grub. Once you've manually copied the bzImage file, and the initrd or initramfs if you're using one, you need to inform Grub of the new kernel. With simple setups, it's just a matter of running update-grub. Since you're booting one distibution's kernel with another distribution's bootloader, this may not work, so you may need to edit the Grub configuration file manually. That's /boot/grub/menu.lst for Grub legacy (Grub 0.9x) and /boot/grub.grub.cfg for Grub2 (Grub 1.9x).

For Grub2, you need an entry like

menuentry "Homemade 3.5 kernel" {
    insmod ext2
    set root='(hd0,msdos5)'
    linux /boot/bzImage root=/dev/sda3 ro
}

  • update-grub doesn't detect it. My last Kernel experience was 3.1.8, and I had compiled it right into the source dir, without O=.... Then, grub detected it, but this it doesn't. Also mounting the volume in Ubuntu and retrying the update-grub didn't work. What I wanna know specifically is that "Has my compilation succeeded at all?"

  • I examined maually changing grub.cfg. I get file not found. press any key to continue... which returns to OS selection menu.

  • BTW the most important thing for me to know is that whether my compilation has succeeded or not? Why this kind of behavior is exhibited? And oh, I don't know about initrd, or initramfs. What should I do to them?

  • @ai64 Since make succeeded, your compilation succeeded. What isn't working here is telling your bootloader where to find the new kernel. Please edit your question to add the output of fdisk -l and df, and tell us which partition is your Arch root, which partition is your Ubuntu root, and where /boot is if different. Also post the contents of your Grub configuration file.

I don't think you need to launch make install here, just copy the bzImage generated, System.map, and do make modules_install will just work for you.

You seems to be on Arch Linux, why wouldn't you go for abs ? e.g latest 3.5 kernel is in testing catelog, so if you doabs testings/linux, it should download PKGBUILD files for you, and you do makepkg to build a package

  • I'm not gonna upgrade my Arch's Kernel. I want a fresh, clean raw instance of kernel running for myself. thank you.
