I just installed hwloc 1.6 on a Linux Red Hat system. libnuma is required for linking -- I receive linker errors if I omit -lnuma, and I see that -lnuma is listed in libhwloc.la
under "dependency_libs". However, pkgconfig/hwloc.pc does not mention libnuma. It does mention libpci, though.
Does this sound like an error when hwloc.pc is generated, or am I misunderstanding how pkg-config works? If you give me a pointer, I'd be happy to try an provide a patch.
