Folks, We ran into an issue with the hwloc integration for MPICH. On Mac OS, hwloc detects that OpenCL is available, but the corresponding LDFLAGS are not exported upstream to MPICH, causing application builds to fail at the link stage.
See this issue, for example: https://github.com/pmodels/mpich/issues/3449 We were able to fix this by having HWLOC export LDFLAGS upstream: https://github.com/pmodels/hwloc/commit/c2e5db2a47 Please consider integrating this patch into your next release. Thanks, -- Pavan _______________________________________________ hwloc-users mailing list hwloc-users@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/hwloc-users
