# =========================================================================== # http://www.gnu.org/software/autoconf-archive/ax_blas.html # =========================================================================== # # SYNOPSIS # # AX_BLAS([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]]) # # DESCRIPTION # # This macro looks for a library that implements the BLAS linear-algebra # interface (see http://www.netlib.org/blas/). On success, it sets the # BLAS_LIBS output variable to hold the requisite library linkages. # # To link with BLAS, you should link with: # # $BLAS_LIBS $LIBS $FLIBS # # in that order. FLIBS is the output variable of the # AC_F77_LIBRARY_LDFLAGS macro (called if necessary by AX_BLAS), and is # sometimes necessary in order to link with F77 libraries. Users will also # need to use AC_F77_DUMMY_MAIN (see the autoconf manual), for the same # reason. # # Many libraries are searched for, from ATLAS to CXML to ESSL. The user # may also use --with-blas=<lib> in order to use some specific BLAS # library <lib>. In order to link successfully, however, be aware that you # will probably need to use the same Fortran compiler (which can be set # via the F77 env. var.) as was used to compile the BLAS library. # # 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. # # LICENSE # # Copyright (c) 2008 Steven G.
