The problem is that world atoms are greedy with respect to slots, so |
| 10 |
if you have cross-avr/gcc in world then a global `emerge |
| 11 |
- --depclean` will not remove 4.2.2 after 4.2.3 has been installed. |
| 12 |
System atoms are not greedy for slots, so you can solve the problem |
| 13 |
like this: |
| 14 |
|
| 15 |
mkdir -p /etc/portage/profile |
| 16 |
echo "*cross-avr/gcc" >> /etc/portage/profile/packages |
| 17 |
echo "*cross-avr/gcc:3.4" >> /etc/portage/profile/packages |
| 18 |
|
| 19 |
That pull the highest available overall and the highest available |
| 20 |
from the 3.4 SLOT into your system set (the "packages" file is |
| 21 |
documented in `man portage`). Remove the cross-avr/gcc atoms from |
| 22 |
/var/lib/portage/world since you won't need them anymore. Once |
| 23 |
you've done that, a global `emerge --depclean` should remove |
| 24 |
everything except the highest available overall version and the |
| 25 |
highest available from the 3.4 SLOT. |
