kernel compilation : Error in upgrading 2.4.x to 2.6.x

b0nd · 09-18-2005, 07:07 AM

hello there,
summary of what i was trying.......

in /usr/src/linux/

make clean
make mrproper
make xconfig ............ here i loaded the "config" file found in second cd of slackware
vi Makefile
make bzImage
make modules
make modules_install.

now here in last step "make modules_install" i was getting the following error

Code:

root@bond:/usr/src/linux# make modules_install
ln: when making multiple links, last argument must be a directory
make: *** [_modinst_] Error 1
...............

while searching for it on net......i got this this

i too found a "space" on that line........so removed that

tried again the whole procedure of compilation.....

this time everything worked fine.

#cp /usr/src/linux/arch/i386/boot/bzImage /boot/slack/vmlinuz-2.6.9slack
#cp /usr/src/linux/System.map /boot/slack/System.map-2.6.9slack

#ln -s /boot/slack/vmlinuz-2.6.9slack /boot/slack/vmlinuz
#ln -s /boot/slack/System.map-2.6.9slack /boot/slack/System.map

#vi /etc/lilo.conf

partial entries of my lilo.conf

Code:

# End LILO global section
# Linux bootable partition config begins

image = /boot/slack/vmlinuz
  root = /dev/hda8
  label = slack
  read-only


image = /boot/vmlinuz
  root = /dev/hda8
  label = Slackware
  read-only

#/sbin/lilo
#reboot

but for my gr8 disappointment.......i get the following error

Code:

kernel panic-no syncing: VFS: Unable to mount root fs on unknown-block(3,8)

what should i do now.????

regards

Edit: i posted it in "newbie" section..........but later on thought of posting it on slackware forum

Is the driver for your root file system built-in or is it a module? Most distros build everything as a module and start from an initrd ram disk. That way they can handle everyone's taste. For home-built kernels, use Y, not M, as the option for your root file system driver.

root@bond:/usr/src/linux# make modules_install
ln: when making multiple links, last argument must be a directory
make: *** [_modinst_] Error 1
...............

this indiacates that there is something wronf with ur Makefile

post the starting 6-7 lines of ur Makefile here

ya, there was problem with the "Makefile".........but as i have mentioned in the previous post that i've solved that problem.

now the problem lies somewhere else.....

"lwfinger", i'm not sure about that. Is there any way of checking that ?
and moreover i haven't made any entries for "initrd".
should i start from scratch again ?

starting lines of Makefile......

Code:

VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 9
EXTRAVERSION = 2
NAME=Zonked Quokka

# *DOCUMENTATION*
# To see a list of typical targets execute "make help"
# More info can be located in ./README
# Comments in this file are targeted only to the developer, do not
# expect to learn how to build the kernel reading this file.

# Do not print "Entering directory ..."
MAKEFLAGS += --no-print-directory

VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 9
EXTRAVERSION = 2

just check in the above that u do not have any space at the end of any line

also what FS are u using in slackware?? reiserfs???
did u make ur initrd image

mkinitrd -k <version as thename from Makefile> -o /boot/slack/initrd-2.6.12..img

-o is for the path where this file will be
