3rd-party/romio cannot be built with RHEL7 GNU compilers from Open MPI v5

Open ggouaillardet opened this issue 3 years ago • 1 comments

The root cause is romio requires stdatomic.h that is only available from GCC 4.9 (RHEL7 uses GCC 4.8).

`configure --enable-mca-no-build=io-romio314 does not work as expected ...

$ configure --enable-mca-no-build=io-romio341
[...]
checking which components should be disabled... io-romio341

I believe this should be addressed by https://github.com/open-mpi/ompi/pull/12640 correct?
