openmpi needs to be rebuilt with gfortran 4.9.1

[Adam Rall]

Using:
Ubuntu 14.10
Packages (openmpi-bin, libopenmpi-dev, libopenmpi1.6, etc.) from source openmpi 1.6.5-8
gfortran 4.9.1.

When attempting to compile fortran programs--such as the attached test program--using the default openmpi-bin and libopenmpi-dev, the following error message shows up:

use mpi
       1
Fatal Error: Cannot read module file 'mpi.mod' opened at (1), because it was created by a different version of GNU Fortran.

The openmpi packages should be recompiled with the default gfortran 4.9.1.

Note that this also seems to affect mpich: see https://bugs.launchpad.net/ubuntu/+source/mpich/+bug/1389291.

Same bug with hdf5

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Pierre Navaro (navaro)]

Release: 14.10

$ cat test_hdf5.F90
program write_hdf5_data

use hdf5

implicit none
integer(hid_t) :: file_id, error

!Initialize FORTRAN interface.
CALL h5open_f (error)
!Create a new file using default properties.
call H5Fcreate_f("test.h5", H5F_ACC_TRUNC_F, file_id, error);

!Terminate access to the file.
CALL h5fclose_f(file_id, error)

!Close FORTRAN interface.
CALL h5close_f(error)

end program

$ h5fc test_hdf5.F90
test_hdf5.F90:3.4:

use hdf5
    1
Fatal Error: Cannot read module file 'hdf5.mod' opened at (1), because it was created by a different version of GNU Fortran

This bug was fixed in the package openmpi - 1.10.2-7ubuntu2

---------------
openmpi (1.10.2-7ubuntu2) xenial; urgency=medium

  * Debug build for powerpc (-O0 instead of -Og).
