On FreeBSD, defining _POSIX_SOURCE is intended to suppress definitions of all non-POSIX functions, types, constants, etc. This is different than Linux, but that doesn't make it wrong. See, for instance: http://lists.freebsd.org/pipermail/freebsd-standards/2004-March/000474.html So, what else is one to expect when defining _POSIX_SOURCE and including then including the non-POSIX header sys/sysctl.h? I agree that one cannot expect to build hwloc on FreeBSD w/ strict POSIX source enforced. -Paul -- Paul H.
