 Just tested perf build, I see the same errors:

tools/perf/util/evlist.c: In function 'evlist__add_aux_dummy':
/linux/tools/perf/util/evlist.c:266:24: error: implicit declaration of
function 'evlist__dummy_event'; did you mean 'evlist__add_sb_event'?
[-Werror=implicit-function-declaration]
  struct evsel *evsel = evlist__dummy_event(evlist);
                        ^~~~~~~~~~~~~~~~~~~
                        evlist__add_sb_event
linux/tools/perf/util/evlist.c:266:24: error: initialization makes
pointer from integer without a cast [-Werror=int-conversion]

Thanks,
