rebuild world.

This step will take many hours. But Cubieboard can run completely standalone if it is powered via a telephone charger or router.
Power consumption is very low. Two Watts or so.

login via ssh or putty
Code:
nohup emerge -ve --keep-going world &

exit

Thanks to nohup (no hung up) we can exit and shutdown everything but Cubieboard. To check emerge in progress, login and enter:
Code:
tail -f nohup.out

OPTIONAL set next boot to "aruntu":
Code:
mount /dev/mmcblk0p1 /mnt
cp /mnt/uEnv.cb2-aruntu /mnt/uEnv.cb2

OPTIONAL set next boot to "gentoo" when running "aruntu":
Code:
cp /uEnv.cb2-gentoo /uEnv.cb2

This emerge took nearly two days, slow, but much faster than on RaspBerry Pi :)

Irre,

Rather than nohup, you may want to use screen.

Like most ARM boards, cross distcc is a boon.
Install crossdev on a more capable helper.
Build your cross tool chain.
Install distcc on the ARM and helpers

Ensure you have identical versions of gcc for ARM everywhere and then let the helpers do the heavy lifting.

Thanks for tips. For me there is no problem if compilations take some time. Compared to RaspBerry this little box is very fast..
