digikam build fails. Unfortunately that's all I can tell you, since the build process provides no information whatsoever. At the point of failure it merely states: [ 61%] Built target digikamdatabase make[1]: Leaving directory `/var/tmp/portage/media-gfx/digikam-2.6.0/work/digikam-2.6.0_build' make: *** [all] Error 2 * ERROR: media-gfx/digikam-2.6.0 failed (compile phase): * emake failed And that's it. Delving into the CMakeFiles directory reveals this at the end of the CMakeError.log: Determining if the function pthread_create exists in the pthreads failed with the following output: ... /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.1/../../../../x86_64-pc-linux-gnu/bin/ld: cannot find -lpthreads collect2: error: ld returned 1 exit status Rerunning ldconfig and trying again makes no difference. Reproducible: Always Steps to Reproduce: 1. emerge -v media-gfx/digikam Actual Results: emake failed Expected Results: digikam should build and install successfully This is a gcc-4.7.1 system, but I've already resolved incompatibilites with all the other packages, and digikam did in fact previously build under gcc-4.7.1, since it's apparently been patched to do so, but a recent world update seems to have broken something it depends on. ~ #

I just unmasked digikam-2.7.0: same result. Also the same result with 2.8.0 and 2.9.0. Other packages build OK (e.g. okular), so the toolchain is not broken, and revdep-rebuild finds nothing except digikam.
I missed this earlier in the build log: /usr/lib64/libf2c.so.2: undefined reference to `MAIN__' collect2: error: ld returned 1 exit status Then found this: http://forums.gentoo.org/viewtopic-p-7136586.html An update to libf2c fixed the problem.
