Hmmm...well, a little digging says that we probably didn't do this as thoroughly as we should have :-/
Basically, the "MPI I/O Support" line is tied solely to the disable-mpi-io flag. In the 1.6 series, you only had one option for MPI I/O support, and that was romio. So if you disable romio, then you'll get a "failed" reply to those APIs. What we should have done is automatically "disable-mpi-io" if no components were built - i.e., if you disable them all from building. In 1.7, that would mean disabling both romio and ompi-io. In 1.6, that would just mean disabling romio. I'll pass it along to Jeff to see if it can be done - we can certainly change the flag, but maybe not for the 1.6 series On Feb 13, 2014, at 12:01 PM, Blosch, Edwin L <edwin.l.blo...@lmco.com> wrote: > Why does ompi_info –c say “MPI I/O Support: yes” even though I configured > using –disable-io-romio?
