I thought the error was this:
$ mpif90 -o simplex simplexmain579m.for simplexsubs579
/usr/local/openmpi-1.2.8/intel-11/x86_64/include/mpif-config.h(88):
error #6406: Conflicting attributes or multiple declaration of name.
[MPI_STATUS_SIZE]
parameter (MPI_STATUS_SIZE=5)
-----------------^
simplexmain579m.for(147): error #6591: An automatic object is invalid in
a main program. [ISTATUS]
integer ierr,istatus(MPI_STATUS_SIZE)
---------------------^
which seems to only show the definition in mpif-config.h (which is an internal
OMPI file). I could be mis-interpreting those compiler messages, though...
Off-the-wall guess here: is the program doing both "use mpi" *and* "include
mpif.h" in the same subroutine...?
