How to: Compile Linux kernel 2.6

According to the kernel documentation, the kernel should be compiled using gcc 2.95.x, with x >= 3. “apt-get install gcc” under debian gives you a recent gcc (version > 4).

Thanks a lot Gabber Anna,
It’s works for me :-))

any guess about boot loader?

If you also upgraded kernel-devel and headers package you should get updates. No need to upgrade ld.so.conf or cache

Does this kernel support RHEL4 update 5

I am using kernel 2.6.9-55.EL can i upgade the

i am trying it on mandriva 2008.i can not do “$ make menuconfig”.is there any option to do that.please help me to get out of this as soon as possible.i wonder there is no option of “make”.

With 2.6 kernel there is no need for make modules. make builds kernel and modules. Have you ever read the README in kernel source directory?

I tried make 2.6.25 in my desktop (FC5, kernel version 2.6.15), everything goes okay, but failed to boot the new kernel image with the follow error messages:

PCI: BIOS Bug: MCFG area at e0000000 is not E820-reserved
PCI: Not using MMCONFIG

Read Hat nash version 5.0.32 Starting
mount: error mounting /dev/root on /sysroot at ext3: No such device
….

In initrd.img file, I found no libata.ko or any other .ko modules are added before mkrootdev.

Is this problem caused by incorrect or even no HDD controller driver loaded? I did not see appropriate entry for libata in .config file. Do you guys have any suggestion on make it through?

Thanks.

Lin,

Did your problem sorted out?Thans

I followed the above steps in order to compile Linux kernel “linux-2.6.27″ but when tried to boot my system from latest compiled kernel got the Kernel Panic error which says can’t find
file system /boot/root at the start.

please suggest

the same thing happened to me as ravi.

you have compiled a upstream kernel.How should i compile distribution specific kernels,like if i install fedora it has its kernel source in /usr/src/, fedora community might have added its own patches.Will the steps described in this article work for distribution specific kernels?

There is no such thing as bz3.

I tried to cheat and copied over an older .config.. broke something and had to redo all the options by hand : /

Anyways, the instructions worked great with Gentoo. I had to emerge “mkinitrd” but otherwise everything went very quickly, maybe 20 min to compile everything (very short in Gentoo world).

I suggest everyone keep their old kernel and a lilo/grub option for it just incase :) Most of the problems in the comments seem to be from misconfiguring the kernel. If you aren’t sure what your hardware is or don’t have the time to run through every option. I suggest you pop in a live cd and copy “/proc/config.gz” to use as your base config (”gzip -d config.gz” will uncompress it).

If your system is already unusable, pop in a live cd and try the following as root:
“cd /”
“mkdir /mnt/fixme”
“mount /dev/ROOTDRIVE /mnt/fixme”
“mount /dev/BOOTDRIVE /mnt/fixme/boot”
“mount -t proc proc /mnt/fixme/proc”
“chroot /mnt/fixme /bin/bash”

That should put you back into your computer to compile/fix whatever.

You don’t need make modules anymore. I compiled a few times the last days and just make && make modules_install will do.

make command error:
make: *** [.tmp_vmlinux1] Error 1
Kindly suggest solution

I compiled the whole thing and then booted ..I see the updated version of fedora but when I try to run it ..it says kernal panic and doesn’t proceed any further

got some ideas? thanx

Thanks, it works perfectly.

my mail is toldamtorp@gmail.com

NIce step-by-step process, BUT Following error occured during make command of configuration step for linux 2.6.29.2
make[1]: *** [script/kconfig/dochecklxdialog] Error 1
make: *** [menuconfig] Error 2

Plz provide me solution for it.
Thanks

It’s good, but i need your help to compile;boot from a flash drive and configure options such that the size of the kernel is max 5Mb(minimum application like terminal,usb…)
