I've updated media-gfx/exiv2 to 0.25-r1 which triggered rebuild for kde-apps/libkexiv2-4.14.3. Building kde-apps/libkexiv2-4.14.3 failed with: CMakeFiles/kexiv2.dir/kexiv2_p.o: In function `KExiv2Iface::KExiv2::Private::saveToFile(QFileInfo const&) const': kexiv2_p.cpp:(.text+0x4000): undefined reference to `Exiv2::ImageFactory::open(std::string const&)' CMakeFiles/kexiv2.dir/kexiv2comments.o: In function `KExiv2Iface::KExiv2::canWriteComment(QString const&)': kexiv2comments.cpp:(.text+0x50e): undefined reference to `Exiv2::ImageFactory::open(std::string const&)' CMakeFiles/kexiv2.dir/kexiv2iptc.o: In function `KExiv2Iface::KExiv2::canWriteIptc(QString const&)': kexiv2iptc.cpp:(.text+0x19e): undefined reference to `Exiv2::ImageFactory::open(std::string const&)' collect2: error: ld returned 1 exit status distcc[18402] ERROR: compile (null) on localhost failed libkexiv2/CMakeFiles/kexiv2.dir/build.make:466: recipe for target 'lib/libkexiv2.so.11.2.0' failed make[2]: *** [lib/libkexiv2.so.11.2.0] Error 1 make[2]: Leaving directory '/var/tmp/portage/kde-apps/libkexiv2-4.14.3/work/libkexiv2-4.14.3_build' CMakeFiles/Makefile2:118: recipe for target 'libkexiv2/CMakeFiles/kexiv2.dir/all' failed make[1]: *** [libkexiv2/CMakeFiles/kexiv2.dir/all] Error 2 make[1]: Leaving directory '/var/tmp/portage/kde-apps/libkexiv2-4.14.3/work/libkexiv2-4.14.3_build' Makefile:138: recipe for target 'all' failed Reproducible: Always
No problem here. Can you please attach the full build.log?

I get similar errors as soon as I switch the active compiler from gcc-4.8.5 to gcc-5.2.0. It works as soon as I re-emerge exiv2 with gcc-5.2.0 and try again. Not quite sure what happened in your case, did you switch from gcc-4.8 to new stable 4.9.3 in between exiv2 and libkexiv2 updates?

No, I've been using gcc-4.9.3 for a while now. I tried building both packages again a few minutes ago and today it worked just fine. Have no idea what happened yesterday. Sorry, for noise, I'll just resolve this as invalid.
