Emerging media-libs/opencv-3.3.0-r4[lapack] displays the following during configure: Use Lapack: NO This is on a system with virtual/lapack-3.7, sci-libs/lapack-reference-3.7, and: # eselect lapack show lib64: reference Reproducible: Always
I had mkl-gfortran-openmp implementation of lapack installed when I compiled this, using the virtual/lapack-3.7-r100 ebuild from science resp. neurogentoo overlay. In my build it found lapack and compiled, see build log. I can repeat using reference implementation, but it's also from the neurogentoo overlay, i.e. lapack-reference-3.7.0-r100.
