The macro has to 14# be used instead of the standard macro AC_PROG_F77 and will replace the 15# standard variable F77 with the found compiler. 16# 17# MPI-WANTED-TEST is used to test whether MPI is actually wanted by the 18# user. If MPI-WANTED_TEST is omitted or if it succeeds, the macro will 19# try to find out how to use MPI, if it fails, the macro will call 20# AC_PROG_CC to find a standard C compiler instead. 21# 22# When MPI is found, ACTION-IF-FOUND will be executed, if MPI is not found 23# (or MPI-WANTED-TEST fails) ACTION-IF-NOT-FOUND is executed. If 24# ACTION-IF-FOUND is not set, the macro will define HAVE_MPI. 25# 26# The following example demonstrates usage of the macro: 27# 28# # If --with-mpi=auto is used, try to find MPI, but use standard F77 compiler if it is not found. 29# # If --with-mpi=yes is used, try to find MPI and fail if it isn't found. 30# # If --with-mpi=no is used, use a standard F77 compiler instead. 31# AC_ARG_WITH(mpi, [AS_HELP_STRING([--with-mpi], 32# [compile with MPI (parallelization) support. If none is found, 33# MPI is not used. Default: auto]) 34# ],,[with_mpi=auto]) 35# 36# AX_PROG_F77_MPI([test x"$with_mpi" != xno],[use_mpi=yes],[ 37# use_mpi=no 38# if test x"$with_mpi" = xyes; then 39# AC_MSG_FAILURE([MPI compiler requested, but couldn't use MPI.]) 40# else 41# AC_MSG_WARN([No MPI compiler found, won't use MPI.]) 42# fi 43# ]) 44# 45# LICENSE 46# 47# Copyright (c) 2010,2011 Olaf Lenz <olenz@icp.uni-stuttgart.de> 48# 49# This program is free software: you can redistribute it and/or modify it 50# under the terms of the GNU General Public License as published by the 51# Free Software Foundation, either version 3 of the License, or (at your 52# option) any later version. 53# 54# This program is distributed in the hope that it will be useful, but 55# WITHOUT ANY WARRANTY; without even the implied warranty of 56# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
