Question

Gentoo Kernel Compile Problem

Asked by: phil8258

Hi All,

I'm working my way through a Gentoo Linux installation.
All went well up to the point where I have to compile the kernel.

Using command:
livecd / # cd /usr/src/linux

I get response:
bash: cd: /usr/src/linux: No such file or directory

Alternatively, I tried using:
emerge genkernel
zcat /proc/config.gz > /usr/share/genkernel/x86/kernel-config-2.6
genkernel all

But that also stopped with the error:
* ERROR: Kernel source directory "/usr/src/linux" was not found!

Can somebody help me with this please...
Could it be that I was entering these things at the LiveCD root? - if so, how do I change route so that cd /usr/src/linux works?

Many thanks in advance!

Phil.

Yes, the prompt seems to suggest that you are trying to compile the kernel on the liveCD boot.

You should first install linux on the harddrive.  Compiling a kernel is done after the system boots from the hard drive.  Make sure to include the source package of the kernel, compiling tools such as autoconf, automake, and Gcc.

With all said and done, first thing is first, install linux on the harddrive.
Boot the system from the harddrive.
make sure you have /usr/src/linux which I think often is a symbolic link to a /usr/src/linux-version.

Ok, I thought I had been installing on the hard drive up to this point.
I have done the basic package setup successfully, chroot'ed to /mnt/gentoo, made a make.conf etc.
emerge --sync, emerge portage, emerge -epv world, and emerge sys-libs/libstdc++-v3 all worked ok.

Also, though I can't check, i'm sure at the time of doing all of that I was not at a LiveCD prompt.
But it has slipped back to the CD now...

Presuming that I have infact installed to the hard drive, how do I change from LiveCD / # to the harddrive prompt, so as I can run the command cd /usr/src/linux and then make menuconfig??

Cheers,

Phil.

reboot the system with the livecd out.
Once the system boots from the harddrive. You can get the new kernel and then configure it as you see fit.  Make sure to leave the original in place so that you can boot the system in the event the kernel you compile does not boot your system.

i've got it sorted.
I had not done "emerge gentoo-sources"

Cheers.
