Ralph,
i made PR 782 for this
https://github.com/open-mpi/ompi/pull/782
and i am still double checking it.
i am still wondering whether we should add an MCA parameter for the api
check
(no test, test and fail, test and warn) ...
or i am even wondering whether we should simply remove this test, since
i am not 100% convinced
the test is bulletproof :
if ofed version is different between compilation and runtime, let
openmpi crash
since this is a user-side problem.
Cheers,
Gilles

Yeah, I recall your earlier email on the subject. Sadly, I need
someone from Mellanox to look at this as I don't have access to such
equipment.
Josh? Mike? Gilles? Can someone please look at this?

Hi,
I updated our OpenMPI install from 1.8.3 to 1.8.8 today and I'm
getting
this error:
XRC error: bad XRC API (require XRC from OFED pre 3.12).
This happens even using the exact same node to compile and run an
example program. I saw a thread from a few weeks ago discussing this
issue as well. I changed the dlsym if statement in btl_openib_xrc.c to
this:
if (NULL != dlsym(lib, "ibv_create_xrc_recv_qp@@IBVERBS_1.1")) {
This seems to make the error message go away, so there must be
something
about that check that doesn't work right without the version in it.
This is on a Scientific Linux 6.6 machine with MLNX_OFED 1.5.3-4.0.42.
