dnl

|
dnl Test a variety of MPI options:
|
||
|
|
dnl --enable-mpi - Turns MPI compiling mode on
|
||
|
|
dnl --with-mpi - specify root directory of MPI
|
||
|
|
dnl --with-mpi-compilers - Turns on MPI compiling mode and sets the MPI C++
|
||
|
|
dnl compiler C, and Fortran
|
||
|
|
dnl --with-mpi-incdir - specify include directory for MPI
|
||
|
|
dnl --with-mpi-libs - specify MPI libraries
|
||
|
|
dnl --with-mpi-libdir - specify location of MPI libraries
|
||
|
|
dnl
|
||
|
|
dnl If any of these options are set, HAVE_MPI will be defined for both
|
||
|
|
dnl Autoconf and Automake, and HAVE_MPI will be defined in the
|
||
|
|
dnl generated config.h file
|
||
|
|
dnl
|
||
|
|
dnl if --disable-mpi, then Zoltan will build serial MPI.
|
||
|
|
dnl
|
||
|
|
dnl --enable-mpi and --with-mpi-compilers are the default.
|
||
|
|
dnl
|
||
|
|
dnl --without-mpi is actually a user error, but we'll interpret it as --disable-mpi
|
||
|
|
dnl
|
||
|
|
dnl If CC, CXX, F77 and/or F90/FTN/FC have been set by the user, and MPI compilers
|
||
|
|
dnl are desired, these will be assumed to be the MPI compilers.
