# $NetBSD: blas.buildlink3.mk,v 1.3.2.1 2022/10/03 11:25:45 bsiegert Exp $
#
# This Makefile fragment is meant to be included by packages that use any
# BLAS (Basic Linear Algebra System) implementation instead of one particular
# one.
#
# Since pkgsrc always ships BLAS and LAPACK together (as upstream
# implementations do), this adds both BLAS_LIBS and LAPACK_LIBS to the linker
# flags. Often, they will be identical or at least redundant. LAPACK_LIBS
# does include BLAS_LIBS, in any case.
#
# The C interfaces CBLAS and LAPACKE are also selected
# via BLAS_C_INTERFACE in the package and respective CBLAS_LIBS and
# LAPACKE_LIBS are set. Also, BLAS_INCLUDES is set to preprocessor
# flags to locate/use respective headers.
#
# Note that use of the Accelerate framework is experimental and only
# attempted if user and package explicitly want it.
#
# Keywords: blas lapack netlib atlas openblas mkl
#
# === User-settable variables ===
#
# PKGSRC_BLAS_TYPES
# This value specifies an exhaustive list of BLAS implementations we wish to
# use in this pkgsrc installation, in descending order of preference.
# The implementation selected for a build will be the first one in
# PKGSRC_BLAS_TYPES that also appears in BLAS_ACCEPTED (see below).
# Typically set in mk.conf.
#
# Possible: one or more of netlib, openblas, openblas_pthread,
# openblas_openmp, accelerate.framework
# (Accelerate has differing API and needs special handling, might
# be supported in a few specific packages ony.)
#
# Default: All currently supported implementations (${_BLAS_TYPES})
# except accelerate.framework
#
# === Package-settable variables ===
#
# BLAS_ACCEPTED
# This is a list of blas packages that are compatible with the current
# package. If not set, any BLAS implementation is OK.
# Typically set in package Makefile.
#
# BLAS_C_INTERFACE
# Set to yes if the package requires CBLAS or LAPACKE. This defines
# BLAS_INCLUDES and pulls in additional packages for netlib. Optimized
# implementations include the C interfaces in the main library anyway,
# but you still have the effect on BLAS_INCLUDES.
#
# BLAS_INDEX64
# Set to yes if the package wants to utilize 64 bit indices.
#
# === Variables automatically set here for use in package builds ===
#
# BLAS_TYPE
# This is the BLAS implementation chosen for a particular package build from
# PKGSRC_BLAS_TYPES and BLAS_ACCEPTED. If PKGSRC_BLAS_TYPES and
# BLAS_ACCEPTED have no implementations in common, it defaults to none
# and the build fails.
# BLAS_LIBS
# Linker flags used for linking to BLAS library
# LAPACK_LIBS
# Linker flags used for linking to LAPACK library
# (including BLAS)
# CBLAS_LIBS
# Linker flags used for linking to CBLAS library
# (including BLAS)
# LAPACKE_LIBS
# Linker flags used for linking to LAPACKE library
# (including BLAS and LAPACK)
# BLAS_INCLUDES
# Preprocessor flags to locate/use C interfaces
# (both for CBLAS and LAPACKE)
# BLAS_PC, CBLAS_PC, LAPACK_PC, LAPACKE_PC
# Names of pkg-config modules for the respective API. For optimized BLAS,
# they will usually be identical.
