Libbpf is included as a submodule in this repo. You'll need to build and install
it for the C-based examples to build correctly. (See libbpf/README.md for more
details.)
cd libbpf/src
make install
cd ../..Building bpftool
There are several examples using bpftool throughout the book. To get a version
with libbfd support (which you'll need if you want to see the jited code in the
Chapter 3 examples) you might need to build it from source:
cd ..
git clone --recurse-submodules https://github.com/libbpf/bpftool.git
cd bpftool/src
make install bpftool binaries are now also available from https://github.com/libbpf/bpftool/releases these days.
