I think that lbann is broken due to persistent C++ errors.

@tbennun Maybe you know how to compile lbann, since you regularly commit into this repository?

rev. d7c5780
clang-16
FreeBSD 14.0

[tbennun]

@yurivict yes, you can see how LBANN is compiled on our GitHub CI. I have never encountered those two compiler errors, so I think it could be some dependency version mismatch?
For example, the lack of MPI_Request seems to indicate that MPI headers are not included. Do you compile without Aluminum?

[yurivict]

@tbennun
I compile without Aluminum. But even when Aluminum is present it isn't discovered by cmake and it prints:

LBANN_HAS_ALUMINUM: FALSE

MPICH headers are installed in /usr/local/include.
