compile a new kernel in RHEL 5

Hi all,

I need some help in compiling a new kernel. I am using RHEL 5 with kernel version 2.6.18.

I have downloaded a kernel from link [HTML]http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.20.6.tar.bz2[/HTML]

Code:

1. cd /usr/src

2. wget -c http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.20.tar.bz2

3. tar xvfj linux-2.6.20.tar.bz2

4. cd linux-2.6.20

5. make clean && make mrproper

6. make menuconfig

7  make clean

8. make bzImage

9. make modules

10. make modules_install

11. mkinitrd /boot/initrd-2.6.20.img 2.6.20

I am following this article [HTML]http://www.digitalhermit.com/linux/Kernel-Build-HOWTO.html#CONFIGURATION-2-6[/HTML]

I have completed these steps (till 10) with no errors, BUT when I am trying the 11 th step, no new kernel img file is found.
It only has the old file i.e initrd-2.6.18.img.

Also, few parameters in the make menuconfig are bit confusing, it would be really great if someone has any ebook regarding the parameters.

Pls help !!

Thanks in Adv.

Well you been reading old information, the steps in order are;

make mrproper
make oldconfig (this will get you very close to a working kernel as supplied by Red Hat)
make menuconfig (or config or xconfig);this is where one can tweak the configuration
make
make modules_install
make install

Sorry, no ebook but one can download the 'Linux kernel in a netshell" here (direct link);

Hi Lenard,

THANKS A TON.

your steps really helped me.

Your welcome, glad to help.

FYI: they are not my steps they all come from reading "The Linux kernel in a nutshell"

Problem building on amd64

I'm trying to build kernel 2.6.18-53.1.6.el5-x86_64

rhel5 on amd64.

I get the following error from make mrproper:

scripts/Makefile.clean:17: /usr/src/kernels/2.6.18-53.1.6.el5-x86_64/drivers/infiniband/hw/amso1100/Makefile: No such file or directory
make[3]: *** No rule to make target `/usr/src/kernels/2.6.18-53.1.6.el5-x86_64/drivers/infiniband/hw/amso1100/Makefile'. Stop.
make[2]: *** [drivers/infiniband/hw/amso1100] Error 2
make[1]: *** [drivers/infiniband] Error 2
make: *** [_clean_drivers] Error 2

I removed and reinstalled the kernel src and still get the same error.

thanks for your sugestions,
Andrew

Why???? Are you sure you don't really just need to install the kernel-devel rpm package??

Maybe something like: yum install kernel-devel

You do know that one needs to prep the kernel source when installed from the Red Hat supplied source rpm file??

From the /usr/src/redhat/SPECS directory: rpmbuild -bp --target=`uname -m` kernel-2.6.spec

FYI: tagging on to a pretty much closed thread is considered rude by some, vikas027 did state that he/she was helped.

Sorry for the lapse in etiquette.

I'll go read Linux kernel in a netshell, and post a new thread if need be.

Andrew

This is no biggie to me, I just letting you know for the future.

I asked why because in many cases one does not need to re-build or build the kernel from the src.rpm file as supplied from Red Hat. This may be of interest to you;

These are my notes, may be it can help you out.

First install these two packages, I prefer yum

Code:

yum install ncurses-devel

yum groupinstall "Java Development"

Code:

1. cd /usr/src

2. wget -c http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.20.tar.bz2

3. tar xvfj linux-2.6.20.tar.bz2

4. cd linux-2.6.20

5. make clean && make mrproper

6. make oldconfig (this will get you very close to a working kernel as supplied by Red Hat)

7. make menuconfig (or config or xconfig);this is where one can tweak the configuration

8. make

9. make modules_install

10. make install

11. mkinitrd /boot/initrd-2.6.20.img 2.6.20 

12. cp .config /boot/config-2.6.20

13. cp arch/i386/boot/bzImage /boot/vmlinuz-2.6.20

14. cp System.map /boot/System.map-2.6.20

15. ln -s /boot/System.map-KERNEL_VERSION /boot/System.map

These steps worked fine for me.

I am not an expert, but this brought two kernel options for me in the GRUB menu. May be you can get an idea from this.
