Hi,
what is the preferred way to recover the situation
of this upstream incident ?
currently we have on 1.6.3:
libopenmpif90_3 usr/bin/cygmpi_f90-3.dll
if I follow upstream on next 1.6.4
libopenmpif90_1 usr/bin/cygmpi_f90-1.dll
Currently no package depends on libopenmpif90_3
Regards
Marco

Was the change for libmpi_f90 in VERSION intentional or a typo?
This is from openmpi 1.6.3
libmpi_f90_so_version=4:0:1
1.6.1 had
libmpi_f90_so_version=2:0:1
It was both intentional and a typo.
Specifically, it really should have bee 4:0:3. :-(
Meaning: we unintentionally broke the F90 ABI for 1.6.3 (specifically:
OMPI applications compiled to utilize "use mpi"). :-( :-( :-(
This ABI compatibility will be restored in 1.6.4.

See these commit messages for a fuller explanation:
https://svn.open-mpi.org/trac/ompi/changeset/27471
https://svn.open-mpi.org/trac/ompi/changeset/27558
The short explanation is that, in terms of the "use mpi" interface, all
Open MPI 1.6.x versions are ABI compatible except 1.6.3.
These work:
- compile a "use mpi" OMPI application with 1.6.x (where x!=3), change
your LD_LIBRARY_PATH to point to a different OMPI 1.6.x installation
(where x!=3)
- compile a "use mpi" OMPI application with 1.6.3, use it with OMPI
1.6.3 installation
These do not:
- compile a "use mpi" OMPI application with 1.6.x (where x!=3), change
your LD_LIBRARY_PATH to point an OMPI 1.6.3 installation
- compile a "use mpi" OMPI application with 1.6.3, use it with OMPI
1.6.x installation (where x!=3)
I will make an FAQ item about this so that the result is google-able.
