Problem in compiling kernel

[Ponkumaran Annadurai]

Hello,

I encountered the following error while compiling the kernel version
linux-2.6.39.1. So I am giving here what I got on my screen.

w00t? Yobjdump? the best I know is "objdump", but never "Yobjdump".

BTW, you do have binutils package installed, right?

And this kernel tarball is 100% valid, right? Have you confirmed it by
checking its MD5sum/SHA1sum or something like that? Who knows it's
just a matter of corrupt downloaded file...

Have you tried to setup some sort of cross-compilation environment?
Could you check CROSS_COMPILE env variable?

thanks,
Daniel.

OK, then that's your problem. CROSS_COMPILE is a string
pointing to your cross compiler prefix.

thanks,
Daniel.

Please keep kernelnewbies to CC:, so that other can read about this problem
if they hit it.

The reason for which it didn't work is that you haven't set a valid
cross-compiler
prefix in CROSS_COMPILE

When you set a cross-compiler prefix, the value stored in CROSS_COMPILE is
concatenated with the name of each tool used to compile your kernel.

For example, objdump will be used as ${CROSS_COMPILE}objdump. You set
CROSS_COMPILE=Y, and the tool to be used is now named Yobjdump, which
obviously doesn't exist.

Valid values for CROSS_COMPILE look like this: CROSS_COMPILE=
mips64-octeon-linux-gnu-.

Hope that things are now more clear.

thanks,
Daniel

I got struck in making initrd file, I got the following error


root at rocker:/boot# mkinitramfs -o  initrd.img-2.6.39.1 2.6.39.1Y
W: Possible missing firmware /lib/firmware/rtl_nic/rtl8105e-1.fw for module

r8169
W: Possible missing firmware /lib/firmware/rtl_nic/rtl8168d-1.fw for module

can you suggest me the proper ways to compile a kernel?

2.6.39.1Y? - shouldn't it be 2.6.39.1.

These days I cooked a script to compile the kernel. Perhaps it helps.

KERNEL_DIR=/home/daniel/src/linux
KERNEL_VER=3.0.0-rc4

cd $KERNEL_DIR

#build kernel and images
make bzImage
make modules
make modules_install

#copy newly created image to /boot

cp $KERNEL_DIR/arch/x86/boot/bzImage /boot/vmlinuz-$KERNEL_VER
cp $KERNEL_DIR/.config /boot/config-$KERNEL_VER
cp $KERNEL_DIR/System.map /boot/System.map-$KERNEL_VER

#setup initrd image
cd /boot
mkinitramfs -o initrd.img-$KERNEL_VER $KERNEL_VER

thanks,
Daniel.

Daniel, I guess Ponkumaran did something (wrong) with extra
version...what do you think?

Mulyadi, I don't see how he could have changed EXTRA_VERSION from Makefile.

Ponkumaran, could you try running:
# mkinitramfs -o? initrd.img-2.6.39.1 2.6.39.1

thanks,
Daniel.

I don't know :). I would recommend you to start a fresh install. It's
obvious that you've did something wrong in the first time.

Compiling the kernel should be fairly easy.
thanks,
Daniel.

Great job man!!! Your explanation also clearly explain to me how this
option works. Thanks!
