# This PortGroup sets up variants for serial linear algebra (Accelerate/ATLAS/OpenBLAS/OpenBLAS-devel).
# PortGroup linear_algebra 1.0
# If only BLAS and not LAPACK is used, set:
# If BLAS/LAPACK are only called from C and not Fortran, then Accelerate can be used
# directly and vecLibFort is not needed. Set:
# linalg.setup noveclibfort
# in pre-configure, a line like this may be needed:
# configure.args-append --with-blas="-L${prefix}/lib ${linalglib}"
# If +threads and +atlas are set, the threaded ATLAS library will be used.
