Part Two: Setting up the Prerequisites

Assumptions

All the examples will be run on Ubuntu Linux. On other distributions your mileage may vary

First step: setup dependencies

Install packages

$ sudo apt install clang llvm libelf-dev libpcap-dev build-essential libc6-dev-i386  \
graphviz  make gcc libssl-dev bc libelf-dev libcap-dev clang gcc-multilib  \
libncurses5-dev git pkg-config libmnl-dev bison flex linux-tools-$(uname -r)

Verify that you have bpftool installed on your system

$ sudo bpftool prog 

If there are problems installing it from a package, you can install it from source:

$ git clone --recurse-submodules https://github.com/libbpf/bpftool.git
$ cd bpftool/src
$ make -j$(nproc)
$ sudo https://raw.githubusercontent.com/stevelatif/articles/main/blogs/bpftool prog

Install rust, following the instructions at https://rustup.rs/

$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Once you have rust and cargo installed and in your path, install the following rust related tools:

$ rustup udpate
$ cargo install cargo-generate
$ cargo install bpf-linker
$ cargo install cargo-generate
$ cargo install rustfmt
$ cargo install bpf-linker
