This must be the most confusing advice I ever got :-)
As suggested, I tried:
pacman -Syu blas-openblas
which resulted in:
:: Starting full system upgrade...
looking for conflicting packages...
:: blas-openblas and cblas are in conflict. Remove cblas? [y/N] n
error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: blas-openblas and cblas are in conflict
So what should I do if I want to keep cblas, lapack, numpy, scipy
etc.. working ?
Which blas is now 'the default one' ?
