Subject: Re: [OMPI devel] How to read OPAL_OUTPUT-ed strings
From: Jeff Squyres (jsquyres) (jsquyres_at_[hidden])

OPAL_OUTPUT is the exact equivalent of opal_output(), except that it is complied out for non-debug builds.

So if you did a production build (E.g., a vpath build), OPAL_OUTPUT() will be compiled out. Otherwise, we typically use stream 0 for debugging stuff.
