Is the issue documented publicly? I'm puzzled, because it certainly
works in a simple case:
$ cat x.f90
use mpi
integer size, ierror
double precision d
call mpi_sizeof (size, size, ierror)
print *, size
call mpi_sizeof (d, size, ierror)
print *, size
end
$ mpif90 --showme:version
mpif90: Open MPI 1.8.3 (Language: Fortran)
$ mpif90 --showme:command
gfortran
$ mpif90 x.f90 && ./a.out
4
8
The missing routine is in the library for me:
$ nm -D $MPI_LIB/libmpi_usempi.so | grep mpi_sizeof0di4_
0000000000001cf0 T mpi_sizeof0di4_
I don't understand how it can work generally with mpif.h (f77?), as
implied by the man page, rather than the module.
