10 | # DESCRIPTION
|
---|
11 | #
|
---|
12 | # This macro tries to find out how to compile C programs that use MPI
|
---|
13 | # (Message Passing Interface), a standard API for parallel process
|
---|
14 | # communication (see http://www-unix.mcs.anl.gov/mpi/).
|
---|
15 | # The macro has to be used instead of the standard macro AC_PROG_CC
|
---|
16 | # and will replace the standard variable CC with the found compiler.
|
---|
17 | #
|
---|
18 | # MPI-WANTED-TEST is used to test whether MPI is actually wanted by
|
---|
19 | # the user. If MPI-WANTED_TEST is omitted or if it succeeds, the
|
---|
20 | # macro will try to find out how to use MPI, if it fails, the macro
|
---|
21 | # will call AC_PROG_CC to find a standard C compiler instead.
|
---|
22 | #
|
---|
23 | # When MPI is found, ACTION-IF-FOUND will be executed, if MPI is not
|
---|
24 | # found (or MPI-WANTED-TEST fails) ACTION-IF-NOT-FOUND is
|
---|
25 | # executed. If ACTION-IF-FOUND is not set, the macro will define
|
---|
26 | # HAVE_MPI.
|
---|
27 | #
|
---|
28 | # EXAMPLE
|
---|
29 | #
|
---|
30 | # # If --with-mpi=auto is used, try to find MPI, but use standard C
|
---|
31 | # compiler if it is not found.
|
---|
32 | # # If --with-mpi=yes is used, try to find MPI and fail if it isn't
|
---|
33 | # # found.
|
---|
34 | # # If --with-mpi=no is used, use a standard C compiler instead.
|
---|
35 | # AC_ARG_WITH(mpi, [AS_HELP_STRING([--with-mpi],
