The hwloc git submodule just got merged (https://github.com/open-mpi/ompi/pull/6821).
A new age is upon us! Be sure you read the wiki before you complain here about your builds being broken. :-) https://github.com/open-mpi/ompi/wiki/GitSubmodules On Jan 8, 2020, at 9:04 AM, Ralph Castain via devel <devel@lists.open-mpi.org<mailto:devel@lists.open-mpi.org>> wrote: Actually, I take that back - making a separate PR to change the opal/pmix embedded component to a submodule was way too painful. I simply added it to the existing #7202.

The first will replace opal/pmix with direct use of PMIx everywhere and replace the embedded pmix component with a submodule pointing to PMIx master, and the second will replace ORTE with PRRTE.

At last one of these first two PRs will likely be merged "Real Soon Now". We've been talking about using Git submodules forever. Now we're just about ready. ************************************** *** DEVELOPERS: THIS AFFECTS YOU!! *** ************************************** You cannot just "clone and build" any more: ----- git clone g...@github.com<mailto:g...@github.com>:open-mpi/ompi.git cd ompi && ./autogen.pl && ./configure ... ----- You will *have* to initialize the Git submodule(s) -- either during or after the clone. *THEN* you can build Open MPI.
