I’m reinstalling arpack, atlas, and octave during completion of MacPorts migration to macOS Sierra.
On El Capitan, my installed ports included: arpack @3.3.0_3+atlas+gfortran atlas @3.10.2_2 octave @4.0.3_1+app+atlas+docs+fltk+gfortran+graphicsmagick+qt4gui+sound-accelerate-java I began now with: sudo port install arpack -accelerate+atlas (1) Should I have added +gfortran there, since for octave I’m going to be including variant +gfortran ? (2) Is there any particular reason to use a +gccxx variant with atlas? --- Murray Eisenberg murrayeisenb...@gmail.com 503 King Farm Blvd #101 Home (240)-246-7240 Rockville, MD 20850-6667 Mobile (413)-427-5334
