Subject: Re: [OMPI devel] 1.7.4 status update
From: Jeff Squyres (jsquyres) (jsquyres_at_[hidden])
Date: 2014-01-22 21:41:11

Ok, here's my update: I fixed a bunch of issues in the Fortran support today; most are minor, but they took a while to verify (and some are slated for v1.7.5 because they aren't critical). I also added the ability to disable building the mpi_f08 module.

Here's what's on the trunk / v1.7, and will be in nightly tarballs soon (v1.7 is building now; I have to re-start the trunk one when v1.7 finishes because I goofed and it failed the first time):

- Fix for MPI_STATUS_IGNORE issue (a side-effect of the "protected" update the other day)
- Add some missing interfaces for MPI_Neighbor subroutines
- Add missing interfaces for the profiled versions of the MPI_Dist_graph subroutines
- Add missing pre-defined function callbacks in the mpi_f08 module

Here's what's on the trunk and still awaiting a code review (probably tomorrow) before it can go to v1.7:

- --enable-mpi-fortran behavior now allows you specify up to what level of Fortran bindings you want built:

  --enable-mpi-fortran: tries to build them all (this is the default)
  --enable-mpi-fortran=mpifh: only builds mpif.h support
  --enable-mpi-fortran=usempi: builds mpif.h and use mpi support
  --enable-mpi-fortran=usempif08: builds mpif.h, use mpi, and use mpi_f08 support
  --disable-mpi-fortran: does not build any Fortran support

So to disable the mpi_f08 bindings, you can --enable-mpi-fortran=usempi.
