SYNOPSIS

ACX_MPI([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])

DESCRIPTION

This macro tries to find out how to compile programs that use MPI (Message Passing Interface), a standard API for parallel process communication (see http://www-unix.mcs.anl.gov/mpi/)

On success, it sets the MPICC, MPICXX, MPIF77, or MPIFC output variable to the name of the MPI compiler, depending upon the current language. (This may just be $CC/$CXX/$F77/$FC, but is more often something like mpicc/mpiCC/mpif77/mpif90.) It also sets MPILIBS to any libraries that are needed for linking MPI (e.g. -lmpi or -lfmpi, if a special MPICC/MPICXX/MPIF77/MPIFC was not found).

If you want to compile everything with MPI, you should set:

    CC="MPICC" #OR# CXX="MPICXX" #OR# F77="MPIF77" #OR# FC="MPIFC"
    LIBS="$MPILIBS $LIBS"

NOTE: The above assumes that you will use $CC (or whatever) for linking as well as for compiling. (This is the default for automake and most Makefiles.)

The user can force a particular library/compiler by setting the MPICC/MPICXX/MPIF77/MPIFC and/or MPILIBS environment variables.

ACTION-IF-FOUND is a list of shell commands to run if an MPI library is found, and ACTION-IF-NOT-FOUND is a list of commands to run if it is not found. If ACTION-IF-FOUND is not specified, the default action will define HAVE_MPI.
