Hi Alan, |
| 2 |
|
| 3 |
first of all, which portage version are you using? Even if you are otherwise |
| 4 |
always running a stable system, in this case it might be useful to update |
| 5 |
portage (only) to ~arch. The errors that you are seeing are in an area of the |
| 6 |
dependency resolver that people are actively working on now, and nearly all |
| 7 |
gentoo devs are running ~arch portage. |
| 8 |
|
| 9 |
Add |
| 10 |
sys-apps/portage ~amd64 |
| 11 |
in /etc/portage/package.accept_keywords, then |
| 12 |
emerge -a1u portage |
| 13 |
|
| 14 |
Then, let's first fix the REQUIRED_USE issue from the end of the log. This is |
| 15 |
something portage cannot do on its own. |

I suggest you set the qt4 use flag for libattica (since qt5 is not in the tree |
| 29 |
yet), e.g. add |
| 30 |
dev-libs/libattica qt4 |
| 31 |
to /etc/portage/package.use |
| 32 |
|
| 33 |
Then try again... Things might work now. |
| 34 |
If not, try backtrack 1000. |
| 35 |
If not, ... better send the new error message. |
| 36 |

All the other messages are caused by the subslot rebuild mechanism: If you |
| 49 |
check in detail, from the "two different packages" pulled in, the old one |
| 50 |
always has a "subslot setting", e.g. app-text/poppler:0/43 (the "/43") and the |
| 51 |
new required version has a different subslot (not printed unfortunately, but |
| 52 |
app-text/poppler-0.26.1 has "/46"). Similar reasoning applies to ICU, Perl, |
| 53 |
and libpng. |
| 54 |
|
| 55 |
This is the area actively under improvement that I mentioned above. Basically |
| 56 |
the difference between "/44" and "/46" tells portage "After upgrading poppler, |
| 57 |
rebuild everything that links against it". |
| 58 |
|
| 59 |
While the automated rebuilds are a very nice thing (they make revdep-rebuild |
| 60 |
and perl-cleaner obsolete), they also make figuring things out for portage |
| 61 |
very very difficult. So, one last resort is to switch them off. Not |
| 62 |
recommended for regular operation, just if there is absolutely no way to get |
| 63 |
around problems. |
| 64 |
|
| 65 |
emerge -vtpuND --backtrack=100 --color y --ignore-built-slot-operator-deps y |
| 66 |
world |
| 67 |
|
| 68 |
What happens now? |
| 69 |
|
| 70 |
(If you run this command without the -p you will have to run "emerge |
| 71 |
@preserved-rebuild" and "perl-cleaner --all" immediately afterwards, maybe |
| 72 |
more than once. Just like in old times.) |
| 73 |
