Subject: Re: [OMPI devel] OpenIB compile error
From: Jeff Squyres (jsquyres_at_[hidden])

Brian and I talked about this more off list and figured out the problem. The issue is that Brian has OFED installed in a non-standard location, so he specified --with-openib=/path/to/ofed. The openib BTL therefore knows where OFED (and verbs.h) is installed, but other OFED-lovin' components don't:

- OOB UD
- BTL UD
- hwloc hwloc142

So it seems like it's finally time to rename and universalize the --with-openib switch.

Ladies and gentlemen, I present: --with-ofed.

This one option will function exactly like --with-openib today, with the exception that all OFED-lovin' components can look at $with_ofed.

For the 1.7/1.8 series, we'll accept --with-openib in lieu of --with-ofed, but we'll print a warning if you do so. We'll delete the --with-openib=dir form of --with-openib in 1.9/2.0 (i.e., --with-openib will just mean "you must build openib; error if you cannot build it").

Speak now if you hate this plan...
