Digikam displays no images: "unable to create io-slave"

[sk-public@…]

With a clean build of digikam 1.8.0, digikam launches but doesn't display any images, complaining of an inability to load kio_digikamalbums and kio_digikamdates.

These files (kio_digikamalbums, kio_digikamdates) do exist, in /opt/digikam-1.8/lib/kde4 and /opt/digikam-1.8/var/macports/software/digikam/1.8.0_0+geoloc+kipi/opt/digikam-1.8/lib/kde4/ from the macports install directory.

Permissions on ~/Library/Preferences/KDE have been set. I've removed and recreated ~/Library/Preferences/KDE/shares, and removed /var/tmp/kdecache-$USER. I've set LDPATH to the directory where they are found. It doesn't change the result.

Got hit by the same problem after upgrading (port upgrade outdated).

Same problem here. Digikam 1.8 runs smoothly on top of the KDE-4.5.3 stuff. After compiling kdepimlibs -edu and -graphics on top of kdelibs 4.5.3 digikam 1.8 still works. As soon as kdelibs 4.6.0 show up the annoying "Error loading 'kio_digikamalbums" drops in ...

Sorry: " after compiling kdepimlibs -edu -graphics (4.6.0) on top of kdelibs 4.5.3"

I forwarded this bug to the KDE/Digikam bug tracker: ​https://bugs.kde.org/show_bug.cgi?id=266735

However, I was not able to verify this bug, because for me Digikam does not even start. :( (I also reported that problem: ​https://bugs.kde.org/show_bug.cgi?id=266733)

@carcode: You should include logs in three curly braces to get a readable formatting.

@jan: Sorry for that unreadable log. When I see that for myself there was no way found by me to edit my post.

Yes, Digikam starts here (compiled with all needed depencies a few days ago), but it complaints about the "kio_digikamalbums". May be there is a missing or wrong setting anywhere but I do not know where to search for. And why does kdeinit4 crashes? All other KDE apps works without any problems here.

So who is responsible now? Are this the MacPorts people, the KDE people or the Digikam people? It seems to me that nobody cares about and each group thinks it might be the fault of the other group. Very frustating...

[jgosmann (Jan Gosmann)]

I would say the Digikam and/or KDE people are responsible. I started creating the portfiles for Digikam and kipi-plugins because those were missing within Macports and it is not that much work. But I do not really have knowledge about the Digikam source code and stuff like that. Therefore it would be probably hard for me to fix this. That's the reason I filed a bug in the KDE bug tracker (which includes Digikam).

Moreover, the problem with Digikam not starting on my machine is still unsolved (Digikam says it cannot find a file, but that file exists and is accessible).

This problem seems to have been resolved with kdelibs4 4.6.1.

[jgosmann (Jan Gosmann)]

Indeed. Digikam shows the images again after installing kdelibs4 4.6.1.

[sk-public@…]

Works for me as also, after update to kdelibs4 4.6.1.
