Herald added a project: All.
`hwloc_cpukinds_get_nr()` and friends were introduced in `hwloc` v2.4, so these changes implicitly bumps the `hwloc` version requirement to 2.4.
I suspect this was not intended.
For example, RHEL8 provides `hwloc 2.2` and requiring `hwloc` not provided by the distro is imho not desirable (for example, conflicts can occur when building a binary linked to a library (such as MPI) that depends on the distro `hwloc`.
The attached patch #ifdef protects (most) the changes when building against `hwloc` < 2.4.
