Choose one of these package sets: + * OpenBLAS (includes both a BLAS and a LAPACK implementation) + * atlas (includes both a BLAS and a LAPACK implementation) + * blas, lapack (the Netlib reference implementations) +If more than one set is installed (assuming there are no packaging conflicts) +then the auto-detection will use the first implementation from this list that +it finds. If in doubt, choose the Netlib reference implementations; other +packages that require a BLAS or LAPACK implementation may not build if they +are not configured to detect/use alternate implementations. |
