11 To build libbpf-based tools, simply run `make`. This will build all the listed
12 tools/applications. All the build artifacts, by default, go into .output
18 Given that the libbpf package might not be available across wide variety of
19 distributions, all libbpf-based tools are linked statically against a version
20 of libbpf that BCC links against (from submodule under src/cc/libbpf). This
