[mvapich-discuss] failed to compile mvapich2 with upstream hwloc-2.2.0

[Subramoni, Hari]

Hi, Honggang.

Please accept my apologies for the delay. I got context switched to other things.

Glad to know that you were able to resolve the issues. If it is not too much trouble, could you please post the resolution as well?

Thx,
Hari.

I checked that we do not use HWLOC_MEMBIND_REPLICATE in our version of HWLoc code. The version in [1] has it, but we have not hit any errors because of it.
