failure to compile with OpenMPI 4.0 due to removed symbols about rsmpi

[frqc]

It seems the problem still exists and the workaround still works. But when will the new version be published btw?

[AndrewGaspar]

Ah, I think this was just overlooked. It looks like MPI_Type_create_hvector has been present since MPI-2. Fix incoming.

[bsteinb]

Ugh indeed. Thanks for reporting this.

[aromazyl]

How to resolve it fininally?

[ExpHP]

This is fixed in master, a new version just needs to be released.

Browsing around, it seems that may currently be blocked on #54? (see #67)

If you are writing an application, you can depend on mpi as a git dependency:

[dependencies]
mpi = { git = "https://github.com/bsteinb/rsmpi", rev = "f9aec8b8d82" }

However, this is a bad idea for libraries that want to be published on crates.io. In that case, you should stick to the current v0.5.x release, and users will need to not use an MPI implementation that isn't OpenMPI 4.x. (they can build OpenMPI 3.1.4 from source)

Why not cherry-pick this solution and release a small version update? We've been waiting for a new version for too long. Before the coming of 0.6, you can actually keep updating 0.5.

There are semver-incompatible changes. I'm hoping to get an hour or so to tie up loose ends and release v0.6 in the near future. #95
