[OMPI users] MPI_CART_CREATE and Fortran 90 Interface

[Michal Charemza]

Hi,

I'm having a bit of trouble getting MPI_CART_CREATE to work with the  
Fortran 90 Interface, i.e. if I "use mpi", I get an error at  
compilation time (of my program) of:

There is no specific subroutine for the generic 'mpi_cart_create'

However, if I include mpif.h this error does not occur. After looking  
into the source, I see that in my mpi-f90-interfaces.h, there is a part:

interface MPI_Cart_create

subroutine MPI_Cart_create(old_comm, ndims, dims, periods, reorder, &
        comm_cart, ierr)
  integer, intent(in) :: old_comm
  integer, intent(in) :: ndims
  integer, dimension(*), intent(in) :: dims
  integer, dimension(*), intent(in) :: periods
  integer, intent(in) :: reorder
  integer, intent(out) :: comm_cart
  integer, intent(out) :: ierr
end subroutine MPI_Cart_create

end interface MPI_Cart_create

I thought according to the MPI specs, periods should be a logical  
array, and reorder should be a logical scalar. Is this a bug in the  
Fortran 90 interface?

Michal.
