compiled kernel too big

fourcs · 04-24-2006, 01:10 PM

My patched slack 2.6.13 kernel patched with patches 2.6.14, 2.6.15, 2.6.16 is 5,055,940 and I'm getting the message that it's too big. I've tried to reduce it with little success. I'm not willing to make it the only kernel available for boot. I'm using lilo. Anyone have any suggestions?

The precise message lilo gave me was:"Fatal: Kernel /boot/vmlinux-custom-2.6.16 is too big". I'm just concerned that lilo won't work. I have no intention of booting from a floppy.

Are u sure u ran 'lilo' after compilation?

Usually, u (I) get this message when forget it...

U can boot from a cd, mount ur partition and run 'lilo'

Move some stuff to modules.

Did you remember to issue the:
make bzImage
to compress it? Then copy the compressed image over to your /boot directory?
cp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinux-custom-2.6.16

Did this, done that!

kriton12 · 04-25-2006, 11:44 AM

Hmm.. I'm still thinking you're copying over the wrong image, can you post the commands exactly as you type them from the command window?

Other than that, I don't really know, sorry.

if I'm getting it right, that number is about 4.82 Mb
hell

that's relatively a lot of a kernel image

you could try to compile a kernel from scratch, just copy over your last .config file and fire up

Code:

make && make modules_install && make install

make install copies the image and the needed files, calls lilo and does the trick just ready to reboot

also it's likely, as kriton12 said, that file is not the proper image file, just another quite bigger one

starting out with the patched 2.6.13 kernel src I do:
make menuconfig
make bzImage

if this doesn't produce the image I want I do:
make clean
make mrproper
make menuconfig
make bzImage

tormented_one · 04-25-2006, 07:27 PM

You may also need
make modules and make modules_install

fourcs · 04-26-2006, 02:12 AM

Thanks for the quick replies. I've found an excellent HOW-TO,http://www.digitalhermit.com/linux/K...FIGURATION-2-6
I was not placing the compressed image in the boot directory. I had to go to the arch/i386/boot to get it. And yes, I didn't make the modules. Thanks again.

make bzImage

You don't need to do this with 2.6, a simple 'make' will compile both the kernel and modules. You could also use checkinstall to create a package. It can create Slackware tgz, rpm and deb packages, which pretty much covers everything except Gentoo but that has it's own installation procedure anyway.

duh, edited wrong page.
