Not entering the chroot properly has been reported as a cause of failing to compile cpio.
Your restart procedure should be: boot the cd | Code: | mount /dev/sda3 /mnt/gentoo
mount /dev/sda1 /mnt/gentoo/boot
mount -t proc none /mnt/gentoo/proc
mount --rbind /sys /mnt/gentoo/sys
mount --rbind /dev /mnt/gentoo/dev
chroot /mnt/gentoo /bin/bash
source /etc/profile
export PS1="(chroot) $PS1" |
Graceful exit should be | Code: | exit
cd
umount -l /mnt/gentoo/dev{/shm,/pts,}
umount -l /mnt/gentoo{/boot,/proc,}
reboot |

boot cd, mount gentoo partitions, | Code: | | wgetpaste /mnt/gentoo/portage/make.conf |
post url
Enter the chroot, | Code: | emerge --sync
emerge portage > /por
emerge --info > /emi
emerge gcc > /gcc
ls /proc > /pro |
exit chroot gracefully except do not reboot, | Code: | wgetpaste /mnt/gentoo/por
wgetpaste /mnt/gentoo/emi
wgetpaste /mnt/gentoo/gcc
wgetpaste /mnt/gentoo/pro
ls -l /mnt/gentoo | wgetpaste

| Quote: | | wgetpaste /mnt/gentoo/portage/make.conf file doesn't exist |
relates to my inability to avoid typos/brain dumps. Should have asked for wgetpaste /mnt/gentoo/portage/make.conf.
boot cd, mount the gentoo partitions, run | Code: | | nano /mnt/gentoo/etc/portage/make.conf |
change | Quote: | | CFLAGS="march=k8 -O2 -pipe" |
to | Quote: | | CFLAGS="-march=native -O2 -pipe" |
ensure you have | Quote: | | CXXFLAGS="${CFLAGS}" |
all this trouble over a missing leading hyphen? Maybe, you'll find out. -march=native is currently preferred over -march=k8 and k8 is for an amd processor while you have an intel cpu.
While you're at it, post a copy of /mnt/gentoo/etc/portage/make.conf after you repair it. Then continue to the chroot and | Code: | emerge -1 cpio
emerge genkernel |

aalrighty, everything now emerges ok!
- makes all the difference.
genkernel fails however  kernel source directory /usr/src/linux not found - sounds like a bit of a fundamental fail

nearly there 
just did the reboot after installing grub and all that....
got an error cannot open root device sda3 - please append a correct root= boot option
at first i thought this was referring to the fstab file so i went a changed it a bit but got the same error
http://bpaste.net/show/87082 - im still not sure its right
then when i re-read the error i thought it was more likely to be my grub config (root= and all that)
so i had a look and i had root as hd0,0 - which is 1st hard drive first partition, which in my case would be sda1 which is the boot partition not root which is sda3 right?
i changed it to 0,2 hoping this would point the root at sda3 but when i tried to boot with this i got;
root (hd0,2)
filesystem type is ext2fs, partition type 0x83
kernel /boot/kernel-genkernel-x86_64-3.7.10-gentoo root=/dev/sda3 init=/bin/bb
error 15: file not found
heres the grub config
http://bpaste.net/show/87083
any ideas where im going wrong? |

indicates missing driver for hard drive. this is consistent with using genkernel to build the kernel and initramfs but not having an initrd specified in grub.conf
| Quote: | | then when i re-read the error i thought it was more likely to be my grub config (root= and all that) |
grub.conf 's root=/dev/sda3 could be wrong but does not sound like it
| Quote: | | so i had a look and i had root as hd0,0 - which is 1st hard drive first partition, which in my case would be sda1 which is the boot partition not root which is sda3 right? |
root in grub.conf means location where grub files can be found; thus (hd0,0) was right as proven by the fact that grub ran correctly and loaded and started the kernel
| Quote: | filesystem type is ext2fs, partition type 0x83
kernel /boot/kernel-genkernel-x86_64-3.7.10-gentoo root=/dev/sda3 init=/bin/bb
error 15: file not found |
proper response to pointing to root (hd0,2) as the location of grub files which it is not
so grub.conf: | Quote: | root (hd0,0)
kernel /boot/kernel-genkernel-x86_64-3.7.10-gentoo root=/dev/ram0 real_root=/dev/sda3
initrd /boot/initramfs-genkernel-x86_64-3.7.10-gentoo |
do check grub.conf spelling is exact match to that in /boot
if your box has no floppy leave the fd0 line out of fstab, if you want cd/dvd automount leave out the cdrom line also

DONE!
i now have a operating system cheers for the help.
just one last question regarding getting my head around where everything is.
when i first boot im at
computername ~ # which according to ls has nothing in it.
if I change directory to / i am now looking at sda3 which is my main partition
so my question is, before I change into the main drives file directory...where am I? what or where is ~# - does it even have a physical location or is it just a virtual space to enter commands?....and what do you call that location ?(assuming that you call / # root) |

you are in the "home" directory. In quotes because home does not necessarily or exacly mean /home.
if you are logged in as root you will be in /root
if you are logged in as adrian you will be in /home/adrian
running ls -al may produce an interesting result
