When building from source code of v5.0.3, it says ‘The submodule "config/oac" is missing.’

Any idea how to fix this? I get the zip from https://github.com/open-mpi/ompi/tags.

Unless you are a developer, you should download the official tarballs from https://www.open-mpi.org/software/ompi/v5.0/

By the way, the latest release is 5.0.6.

Unfortunately, we do need to build from source code. : )

[ggouaillardet]

Did you mean build from git (instead of build from source)?

Sounds like you got the unofficial GitHub tarball - which the OMPI community does not support. You want the official tarball from https://www.open-mpi.org/software/ompi/v5.0/

I think you misunderstood @ggouaillardet -- the releases from https://www.open-mpi.org/software/ompi/v5.0/ are source code releases. The tarballs available from that URL are properly bootstrapped, ready-to-build tarballs.

The naked git clone tarballs you get from https://github.com/open-mpi/ompi/tags are not properly bootstrapped, and do not build properly. This is why we do not have any releases in the GitHub release mechanism; we don't want users to download those non-functional tarballs. We cannot disable GitHub's functionality of publishing naked git tarballs under the "tags" section, unfortunately.

If a bootstrapped source tarball is somehow insufficient, and you really do need to be able to build from a git clone, then you should read https://docs.open-mpi.org/en/v5.0.x/developers/index.html.
