I will just focus on mkl_core for now: ====================================================== OUTPUT OF: ldconfig -v: ====================================================== ... /opt/intel/composerxe-2011.4.191/mkl/lib/intel64: libmkl_core.so -> libmkl_core.so ... /opt/intel/composerxe-2011.4.191/mkl/lib/ia32: libmkl_core.so -> libmkl_core.so ... ====================================================== So the library is there, but ld probably does not use the right path -L to look for it?! I think this should/could be a bug, no? I tried playing around with ld manual: ================================= OUTPUT OF: ld -t -lmkl_core ================================= ld: mode elf_x86_64 ld: cannot find -lmkl_core ================================= ... but of course, THIS works: ld -t -L/opt/intel/composerxe-2011.4.191/mkl/lib/intel64 -lmkl_core So is the setup supposed to be in a way that ld without -L finds the mkl_core lib?

Created attachment 285219 [details] emerge log
eselect for these: blacs Alternatives for blacs blas Alternatives for blas cblas Alternatives for cblas lapacke Alternatives for lapacke lapack Alternatives for lapack scalapack Alternatives for scalapack I first tried it with all of these being set to: mkl64-intel And now I tried setting all of these to: mkl64-int64-intel Both with the result as seen in the emerge log attachment. --- This morning I had installed mkl: [I] sci-libs/mkl (10.3.4.191(10.3)[1]@08/31/2011): Intel Math Kernel Library: linear algebra, fft, math functions [1] "science" /mnt/vola/sd/layman/science (multilib) Maybe this info can be helpful?
After reading: http://www.gentoo.org/proj/en/science/blas-lapack.xml I think I figured it out: clapack was pulled in [only] by media-libs/opencv. And media-libs/opencv-2.2.0.ebuild depending on: >--->=sci-libs/clapack-3.2.1-r4 AND ON: >---virtual/lapack But I noticed that media-libs/opencv-2.3.0 does not depend on either anymore :)
I forgot to mention my conclusion after reading the gentoo.org link: There was written to just redepend on virtual/lapack... so was the explicit clapack rdepend really necessary for opencv-2.2.0? - I didn't [yet] try to compile opencv-2.2.0 just without the explicit clapack rdepend line... but that could be the solution to avoid this problem I ran into? [beside updating to opencv-2.3.0 :]
