 Posted: Sat Oct 22, 2016 1:21 pm Post subject: [SOLVED] Segfault in digikam 4.4.0-r1 |
 |
|
Following this weeks update, digikam's stopped working. It segfaults immediately after startup - you cant even get as far as "digikam -v" working. No back trace, zilch.
I'm running stable AMD64, with the current hybrid KDE5-with-some-KDE4-apps (such as kdepim, digikam, etc.). Was working fine.
I recompiled digikam for debugging and started it with gdb. It gives:
| Code: | gdb digikam
GNU gdb (Gentoo 7.10.1 vanilla) 7.10.1
Copyright (C) 2015 Free Software Foundation, Inc.
...
This GDB was configured as "x86_64-pc-linux-gnu".
...
Reading symbols from digikam...done.
(gdb) run
Starting program: /usr/bin/digikam
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".

My friend Google suggests this may be due to something not liking KDE5 libraries, though it was happy until recently.
A few version levels:
| Code: | media-gfx/digikam-4.4.0-r1
kde-apps/libkipi-16.04.3
dev-qt/qtcore-5.6.1
kde-apps/kdebase-meta-16.04.3 |
I assume something is missing or mis-configured. I'll be grateful for any suggestions.
FWIW, I tried upgrading to media-gfx/digikam-4.14.0-r1but it still segfaults.
media-gfx/digikam-5.1.0-r1 worked-ish, but didn't migrate tags etc. from the internal mysql database, and generally looked like a frightening upgrade prospect

Should be fixed by now, if it is the same problem: media-libs/opencv needs to be compiled with qt4, not qt5:

Yes, that should be it.
digikam-5.3.0 at the end of October will come with another slew of fixes, including some migration stuff, so it will be a good candidate for stabilisation.
