hi,
adding support to link bpftool with libbpf dynamically,
and config change for perf.
It's now possible to use:
$ make -C tools/bpf/bpftool/ LIBBPF_DYNAMIC=1
which will detect libbpf devel package with needed version,
and if found, link it with bpftool.
It's possible to use arbitrary installed libbpf:
$ make -C tools/bpf/bpftool/ LIBBPF_DYNAMIC=1 LIBBPF_DIR=/tmp/libbpf/
I based this change on top of Arnaldo's perf/core, because
it contains libbpf feature detection code as dependency.
It's now also synced with latest bpf-next, so Toke's change
applies correctly.
Also available in:
git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
libbpf/dyn
thanks,
jirka
