trying to compile the 2.6.21.5 kernel

bioe007 · 06-20-2007, 10:54 AM

'xconfig' and 'menuconfig' are not commands, they're make directives

do this:

Code:

cd /usr/src/linux-X.Y.Z
make mrproper             # for a 2.6 kernel
make xconfig

you _shouldn't_ be root for compiling your kernel or the modules, only for installing/copying.

hth

<edit> sorry the 'cd <directory>' can be to wherever you extracted the kernel source.

Of course you're right. Some months ago I had my kernel source tree screwed up and had to call make xconfig/menuconfig as root. Bad habit from that time.

i tried the how to posted at the top of the page and I got it all done its just when i boot into the new vmlinuz file i get a blank screen. I have noticed in the how to it doesn't mention make depend. Wasn't I supposed to do that command sometime in the compile process?

ok maybe its my lilo.conf file here is how it is setup as of now...

Code:

boot="/dev/hda"
lba32
prompt
timeout="300"
root=/dev/hda2
vga="773"
default=linux

image="/boot/vmlinuz"
        label="linux"
        root="/dev/hda2"
        read-only

image="/boot/vmlinuz.old"
        label="linux.old"
        root="/dev/hda2"
        read-only

the linux image is the newly compiled kernel btw

you only do make dep for 2.4 kernels, not required for 2.6+

the blank screen seems like a framebuffer issue. (i.e. something not quite compiled in right)

try commenting out the vga= line:

Code:

boot="/dev/hda"
lba32
prompt
timeout="300"
root=/dev/hda2
#vga="773"
default=linux

image="/boot/vmlinuz"
        label="linux"
        root="/dev/hda2"
        read-only

image="/boot/vmlinuz.old"
        label="linux.old"
        root="/dev/hda2"
        read-only

then run /sbin/lilo, and reboot. you'll likely be greeted by the ugly 40 column console, all that means is you custom kernel config didn't quite get the framebuffer options correct.

btw- here is an alternate way to do the vga= argument:

Code:

boot="/dev/hda"
lba32
prompt
timeout="300"
root=/dev/hda2
#vga="773"
default=linux

image="/boot/vmlinuz"
        label="linux"
        root="/dev/hda2"
        vga=normal
        read-only

image="/boot/vmlinuz.old"
        label="linux.old"
        root="/dev/hda2"
        vga=773
        read-only

this method gives you control over which kernel is booting into which mode. (to some extent anyway)

hopefully booting into your vmlinuz.old still works OK for you and you can modify lilo.conf from there.

another thing the "digital hermit" guide doesnt tell you (cause its distrospefic) is to change your 'rc.modules' link (in /etc/rc.d/) whenever you change kernel versions you should make a 'new' rc.modules-2.X.YY.Z file to insmod any kernel modules you know you want loaded at boot time.

but that is a bit of a distraction, look into the framebuffer support (easiest way is either to live with the ugly console, or compile your fb support into the kernel)

alright, finally, I got it working.

thanks to all
