Grr. kde-base/libkdcraw-4.12 was written with support for only libraw-0.16. At last moment somebody from kde upstream realized that an actual libraw-0.16 release won't happen in time, so 0.15 support was patched back on hastily. This is the result. I'll have to investigate, but I *think* it's not as easy as generally specifying libraw[openmp].
(In reply to Andreas K. Hüttel from comment #4) Well maybe it's enough to bump #506656. Will test later and report back.
I bumped the 0.16.0_beta1-r1 ebuild to 0.16.0 (removing two patches which did not apply), and tried to build against that. Build/linking went fine - cannot test functionality ATM because the machine is non-graphical. HTH
Thanks all. 4.14.3 stable. Cleanup done by Michal. Closing then. + + 18 Feb 2015; Michał Górny <mgorny@gentoo.org> -libkdcraw-4.12.5.ebuild: + Remove KDE SC 4.12 +
