| 5 # SYNOPSIS | |
| 6 # | |
| 7 # AX_BLAS([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]]) | |
| 8 # | |
| 9 # DESCRIPTION | |
| 10 # | |
| 11 # This macro looks for a library that implements the BLAS linear-algebra | |
| 12 # interface (see http://www.netlib.org/blas/). On success, it sets the | |
| 13 # BLAS_LIBS output variable to hold the requisite library linkages. | |
| 14 # | |
| 15 # To link with BLAS, you should link with: | |
| 16 # | |
| 17 # $BLAS_LIBS $LIBS $FLIBS | |
| 18 # | |
| 19 # in that order. FLIBS is the output variable of the | |
| 20 # AC_F77_LIBRARY_LDFLAGS macro (called if necessary by AX_BLAS), and is | |
| 21 # sometimes necessary in order to link with F77 libraries. Users will also | |
| 22 # need to use AC_F77_DUMMY_MAIN (see the autoconf manual), for the same | |
| 23 # reason. | |
| 24 # | |
| 25 # Many libraries are searched for, from ATLAS to CXML to ESSL. The user | |
| 26 # may also use --with-blas=<lib> in order to use some specific BLAS | |
| 27 # library <lib>. In order to link successfully, however, be aware that you | |
| 28 # will probably need to use the same Fortran compiler (which can be set | |
| 29 # via the F77 env. var.) as was used to compile the BLAS library. | |
| 30 # | |
| 31 # ACTION-IF-FOUND is a list of shell commands to run if a BLAS library is | |
| 32 # found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it is | |
| 33 # not found. If ACTION-IF-FOUND is not specified, the default action will | |
| 34 # define HAVE_BLAS. | |
