libperf: Fix build error with LIBPFM4=1
Fix build error with LIBPFM4=1:
CC util/pfm.o
util/pfm.c: In function ‘parse_libpfm_events_option’:
util/pfm.c:102:30: error: ‘struct evsel’ has no member named ‘leader’
102 | evsel->leader = grp_leader;
| ^~
Committer notes:
There is this entry in 'make -C tools/perf build-test' to test the build
with libpfm:
$ grep libpfm tools/perf/tests/make
make_with_libpfm4 := LIBPFM4=1
run += make_with_libpfm4
$
But the test machine lacked libpfm-devel, now its installed and further
cases like this shouldn't happen.
Committer testing:
Before this patch this fails, after applying it:
$ make -C tools/perf build-test
make: Entering directory '/var/home/acme/git/perf/tools/perf'
- tarpkg: ./tests/perf-targz-src-pkg .
make_static: make LDFLAGS=-static NO_PERF_READ_VDSO32=1 NO_PERF_READ_VDSOX32=1 NO_JVMTI=1 -j24 DESTDIR=/tmp/tmp.KzFSfvGRQa
<SNIP>
make_no_scripts_O: make NO_LIBPYTHON=1 NO_LIBPERL=1
make_with_libpfm4_O: make LIBPFM4=1
make_install_prefix_O: make install prefix=/tmp/krava
make_no_auxtrace_O: make NO_AUXTRACE=1
<SNIP>
$ rpm -q libpfm-devel
libpfm-devel-4.11.0-4.fc34.x86_64
$
FIXME:
This shows a need for 'build-test' to bail out when a build option is
specified that has no required library devel files installed.
