Subject: perf build broken seemingly due to libbpf changes, checking...
Date: Thu, 6 Jan 2022 16:34:46 -0300 [thread overview]
Message-ID: <YddEVgNKBJiqcV6Y@kernel.org> (raw)
After merging torvalds/master to perf/urgent I'm getting this:
util/bpf-event.c:25:21: error: no previous prototype for ‘btf__load_from_kernel_by_id’ [-Werror=missing-prototypes]

I'm checking now...
BTW I test perf builds with:
make -k BUILD_BPF_SKEL=1 CORESIGHT=1 PYTHON=python3 O=/tmp/build/perf -C tools/perf install-bin && git status && perf test python
