parallelio build failure with apple-clang 12.0.5 (but not with (llvm-)clang)

[climbfuji]

parallelio fails to build with errors about conflicting type definitions when using apple-clang 12.0.5. This was reported by two people independently. It builds fine on my macOS with llvm-clang@13.0.0.

I will try to reproduce the error and paste the exact error message here.

I tested this on my mac with apple-clang@13.0.0 and parallelio-2.5.2 builds fine. @shlyaeva

I'm going to try again tomorrow, and will post the error message.

Is it this issue? JCSDA/spack#17

Looks like a legitimate build problem, perhaps related to the MPI version.

[kgerheiser]

If so, the fix was merged with NCAR/ParallelIO#1916

We could create a patch from this PR.

@kgerheiser yes, the same issue; patching would be great!
update and I was building with mpich4.0.1, which agrees with the issue reported in NCAR/ParallelIO#1912

[kgerheiser]

Fixed with the submodule update in #88
