dnl @synopsis ACX_BLAS([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
|
|
||||||
dnl
|
|
||||||
dnl This macro looks for a library that implements the BLAS
|
|
||||||
dnl linear-algebra interface (see http://www.netlib.org/blas/). On
|
|
||||||
dnl success, it sets the BLAS_LIBS output variable to hold the
|
|
||||||
dnl requisite library linkages.
|
|
||||||
dnl
|
|
||||||
dnl To link with BLAS, you should link with:
|
|
||||||
dnl
|
|
||||||
dnl $BLAS_LIBS $LIBS $FLIBS
|
|
||||||
dnl
|
|
||||||
dnl in that order. FLIBS is the output variable of the
|
|
||||||
dnl AC_F77_LIBRARY_LDFLAGS macro (called if necessary by ACX_BLAS), and
|
|
||||||
dnl is sometimes necessary in order to link with F77 libraries. Users
|
|
||||||
dnl will also need to use AC_F77_DUMMY_MAIN (see the autoconf manual),
|
|
||||||
dnl for the same reason.
|
|
||||||
dnl
|
|
||||||
dnl Many libraries are searched for, from ATLAS to CXML to ESSL. The
|
|
||||||
dnl user may also use --with-blas=<lib> in order to use some specific
|
|
||||||
dnl BLAS library <lib>. In order to link successfully, however, be
|
|
||||||
dnl aware that you will probably need to use the same Fortran compiler
|
|
||||||
dnl (which can be set via the F77 env. var.) as was used to compile the
|
|
||||||
dnl BLAS library.
|
|
||||||
dnl
|
|
||||||
dnl ACTION-IF-FOUND is a list of shell commands to run if a BLAS
|
|
||||||
dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to
|
|
||||||
dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the
|
|
||||||
dnl default action will define HAVE_BLAS.
|
|
||||||
dnl
|
|
||||||
dnl This macro requires autoconf 2.50 or later.
