# SYNOPSIS
|
|
#
|
|
# AX_CBLAS([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# This macro looks for a library that implements the CBLAS linear-algebra
|
|
# interface (see http://www.netlib.org/blas/). On success, it sets the
|
|
# CBLAS_LIBS output variable to hold the requisite library linkages.
|
|
#
|
|
# To link with CBLAS, you should link with:
|
|
#
|
|
# $CBLAS_LIBS $LIBS
|
|
#
|
|
# in that order.
|
|
#
|
|
# Many libraries are searched for, from ATLAS to CXML to ESSL. The user
|
|
# may also use --with-cblas=<lib> in order to use some specific CBLAS
|
|
# library <lib>.
|
|
#
|
|
# ACTION-IF-FOUND is a list of shell commands to run if a BLAS library is
|
|
# found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it is
|
|
# not found. If ACTION-IF-FOUND is not specified, the default action will
|
|
# define HAVE_BLAS.
|
|
#
|
|
# This macro requires autoconf 2.50 or later.
