So unless I missed something (if I did, it should be added to the commit message), there should rather be a configure check that defines something similar to other code, e.g. HAVE_PERF_CPU_CYCLES and then that should be used in the conditional. There are other places in that and other files which can not be compiled. The obvious fix is to just add a #ifndef x;#define x 0 to get libvirt going. The question is still unanswered if configure should just error out and refuse to go further, or if the few missing pieces should be supplied manually because the affected functionality is optional. See attached patches for how I deal with it. Olaf
