compiling problem

[trashy]

yikes I messed up my first attempt at kernel stuff ... ok it's not as scary as I thought
it would be but still pretty confusing... following this link(as best I understood)..
http://www.yellowdoglinux.com/support/s ... nels.shtml

I updated 2.4.22-2a to 2.4.22-2g no prob. Then I went into the control center and enabled
usb printer and usb v4l(both not as modules)... did the kernel stuff and now
on reboot I get 'Kernel panic: no init found. try passing init= option to kernel'

I did do the steps as in 3a.(kernel.shtlm) Putting the kernel in place, but my System.map
still points to the old kernel. How do I go about changing this?

you can try to specify the correct system.map file for that kernel by adding "sysmap=/boot/System.map-2.4.22-2g" to the yaboot.conf

nope, didn't work. last few lines before 180 seconds to reboot are...

Mount: error 19
Pivot_root failed:2
unmount /init/proc Failed:2

Would it be possible to do the whole process over again starting with going into the control panel, loading kernel 2.4.22g, making changes and compiling again?

when i try to create a new symlink for the new system.map I get file already exists... how do i remove the old symlink?

i tried ln -s ..... so now i would like to try removing the old link and doing ln -s again to the new sysmap.

thanks
(if this would solve anything that is lol)

just delete the old one like you would a file; "rm -f file" beware that you'll need to be root to do this and make sure thats all it deletes. Though honestly when ive had problems with stuff like this when i make a new kernel ive normally had to recompile it and make sure there isnt anything i missed. Also make sure that you depmod (dont remember the extensions-and make all the old modutil files end with .old)

I don´t know the document you read but that should work:

1) Copy the old .config to the directory of the new kernel sources
2) make oldconfig
3) make menuconfig if you need to set special things
4) make dep
5) make vmlinux modules modules_install
6) mv the new vmlinux to /boot/vmlinux-test1
7) mv the new System.map to /boot/System.map-test1
edit /etc/yaboot.conf
9) run ybin -v as root
10) reboot
