romoving this files, cause the same and it happens a error too

Comment 1 Jeroen Roovers gentoo-dev 2012-05-01 22:10:04 UTC
I don't see where that file collision would be coming from - that indicates a problem with the vdb, not the ebuild. Another issue is how emerge itself fails after that.
Comment 2 Zac Medico gentoo-dev 2012-05-01 22:43:04 UTC
Does the file /usr/lib64/ exist on your system?

I've tried the upgrade, and it was successful, resulting in the following preserved libraries:

>>> package: media-libs/cogl-1.10.2
 *  - /usr/lib/
 *  - /usr/lib/
 *      used by /usr/bin/quadrapassel (gnome-extra/gnome-games-3.2.1-r1)

Did the owner get automatically unmerged due to a blocker or something? Or did you unmerge it yourself?

You have 2.2.0_alpha136, which has all of the latest code wrt preserve-libs afaik.
Comment 5 Maurice van der Pot 2014-04-06 10:36:08 UTC
I've just run into this same problem, but with

KeyError: u'<portage.util._dyn_libs.LinkageMapELF._ObjectKey object at 0x9bc9fd8> (/usr/lib64/ not in object list'

Please let me know what info I can provide to help debug this. I have emerge output since the last successful merge before this one as well as emerge.log going back to the previous merge of libpng-1.6.6 to which libpng15 belonged according to the "existing preserved libs" output.

Comment 6 Maurice van der Pot 2014-04-06 12:20:07 UTC
I've done some debugging and found the following.

I'm merging libpng-1.6.9 and is a preserved lib belonging to libpng-1.6.6.

/usr/lib64/portage/pym/portage/dbapi/ does a rebuild of the linkmap excluding libpng (because a new version is going to be installed).

Afterwards it calls self._find_unused_preserved_libs(), which is first going to call _plib_registry.getPreservedLibs() to get all preserved libs and then loop over them calling _linkmap.findConsumers() for each one.

Because the last rebuild of linkmap excluded libpng, the findConsumers call is going to fail with a KeyError.

This is as far as I can get with my limited knowledge of how portage is supposed to work.
