Re: [OMPI devel] Open MPI v5.0.0rc9 is available for testing

Well, --enable-mca-no-build=io-romio341 works strictly speaking (it does not build the io/romio341 component). That being said, it does not prevent 3rd-party/romio from being built, and this is what fails with gcc 4.8 I will file an issue in order to keep track of that. Cheers, Gilles On

This is very odd ... I dumped DISABLE_io_romio341, and it is *not* set (!) Anyway, let's follow-up at https://github.com/open-mpi/ompi/issues/11088 Cheers, Gilles On Fri, Nov 18, 2022 at 5:37 PM Gilles Gouaillardet < gilles.gouaillar...@gmail.com> wrote: > Let me take a step back... > >

Let me take a step back... Looking at the code, it should work ... except it does not :-( $ configure --enable-mca-no-build=io-romio341 [...] checking which components should be disabled... io-romio341 [...] +++ Configuring MCA framework io checking for no configure components in framework

--enable-mca-no-build=io-romio341 should still work. Or just --disable-io-romio. No comment around the RHEL7 part; that's pretty old, but I don't think we've officially said it is too old. Probably something worth filing a ticket for so that we can run to ground before 5.0 release. Oddly,

Re: [OMPI devel] Open MPI v5.0.0rc9 is available for testing

Folks, I tried to build on a RHEL7 like, and it fails at make time because ROMIO requires stdatomic.h (it seems this file is only available from GCC 4.9) Are we supposed to be able to build Open MPI 5 with GCC 4.8 (e.g. stock RHEL7 compiler)? --enable-mca-no-build=io-romio314 cannot
