Hmm.. I can't reproduce it. Those symbols should be in pmu-flex.c:
$ grep 'perf_pmu_in$' -Inr . ./util/pmu-flex.c:15:#define yyin perf_pmu_in
$ grep 'perf_pmu_lex ' -Inr . ./util/pmu-flex.h:292:extern int perf_pmu_lex (void); ./util/pmu-flex.h:294:#define YY_DECL int perf_pmu_lex (void) ./util/pmu-flex.c:650:extern int perf_pmu_lex (void); ./util/pmu-flex.c:652:#define YY_DECL int perf_pmu_lex (void) ./util/pmu-flex.c:946:} /* end of perf_pmu_lex */ ./util/pmu-bison.c:86:extern int perf_pmu_lex (void); ./util/pmu.y:14:extern int perf_pmu_lex (void);
Thanks, Namhyung
