This was fixed recently, merged already, check: https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git/commit/?h=perf/urgent&id=9fb4765451f22c5e782c1590747717550bff34b2 > tools/perf/libperf.a(libperf-in.o): In function `parse_regs': > tools/perf/util/parse-regs-options.c:28: undefined reference to > `sample_reg_masks' > tools/perf/util/parse-regs-options.c:28: undefined reference to > `sample_reg_masks' > tools/perf/util/parse-regs-options.c:45: undefined reference to > `sample_reg_masks' > tools/perf/util/parse-regs-options.c:38: undefined reference to > `sample_reg_masks' > > Fixes: bcc84ec65ad1 ("perf record: Add ability to name registers to record") > Signed-off-by: Ben Hutchings <b...@decadent.org.uk> > Cc: Stephane Eranian <eran...@google.com> > --- > tools/perf/builtin-record.c | 2 ++ > tools/perf/util/Build | 2 +- > 2 files changed, 3 insertions(+), 1 deletion(-) > > diff --git a/tools/perf/builtin-record.c b/tools/perf/builtin-record.c > index 142eeb3..34dd749c 100644 > --- a/tools/perf/builtin-record.c > +++ b/tools/perf/builtin-record.c > @@ -1082,9 +1082,11 @@ struct option __record_options[] = { > "sample transaction flags (special events only)"), > OPT_BOOLEAN(0, "per-thread", &record.opts.target.per_thread, > "use per-thread mmaps"), > +#ifdef CONFIG_PERF_REGS > OPT_CALLBACK_OPTARG('I', "intr-regs", &record.opts.sample_intr_regs, > NULL, "any register", > "sample selected machine registers on interrupt," > " use -I ? to list register names", parse_regs), > +#endif > OPT_BOOLEAN(0, "running-time", &record.opts.running_time, > "Record running/enabled time of read (:S) events"), > OPT_CALLBACK('k', "clockid", &record.opts, > diff --git a/tools/perf/util/Build b/tools/perf/util/Build > index 349bc96..333b08d 100644 > --- a/tools/perf/util/Build > +++ b/tools/perf/util/Build > @@ -83,7 +83,7 @@ libperf-$(CONFIG_AUXTRACE) += intel-pt-decoder/ > libperf-$(CONFIG_AUXTRACE) += intel-pt.o > libperf-$(CONFIG_AUXTRACE) += intel-bts.o > libperf-y += parse-branch-options.o > -libperf-y += parse-regs-options.o > +libperf-$(CONFIG_PERF_REGS) += parse-regs-options.o > > libperf-$(CONFIG_LIBELF) += symbol-elf.o > libperf-$(CONFIG_LIBELF) += probe-file.o > -- > Ben Hutchings > Once a job is fouled up, anything done to improve it makes it worse. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
