#50735: octave @3.8.2: configure: error: BLAS and LAPACK libraries are required ---------------------------+------------------------- Reporter: jainanuj99@… | Owner: michaelld@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: | Keywords: Port: octave | ---------------------------+------------------------- Comment (by michaelld@…): OK; thanks. Is there some specific reason you want to use +nofortran? You have "arrack +gfortran", which indicates that some Fortran is already installed (it is; pick either g95 or gcc5). I'm guessing that "atlas +nofortran" is causing the issue (per ticket #50551). Can you do the following & see what comes of it: {{{ sudo port clean octave sudo port install atlas sudo port install octave }}} Yes, I know that atlas takes a long time to build ... just do it overnight or when you won't need the computer for 8 hours. If you're into Portfile development, try out the [https://trac.macports.org/attachment/ticket/50551/octave_atlas_nofortran_che... patch from that ticket]. -- Ticket URL: <https://trac.macports.org/ticket/50735#comment:5> MacPorts <https://www.macports.org/> Ports system for OS X
