Dependencies

Several dependencies need to be installed before we can build.

  • libz (dynamically linked)
  • libelf (dynamically linked)
  • libncursesw (dynamically linked)
  • clang-15+ (for building BPF program at build time)
  • rustfmt (used by libbpf-cargo for bpf skeleton code generation)

Install build dependencies

Ubuntu

# For Focal (20.04 LTS) or Jammy (22.04 LTS)
sudo apt install -y build-essential ca-certificates clang curl git \
  libelf-dev libncursesw5-dev libssl-dev m4 pkg-config python3 zlib1g-dev

Also check that rustfmt is installed. If you are using rustup, it should be installed by default, but if not, install with:

rustup component add rustfmt

Building

Make sure clang-15 is installed and exported.

export CLANG=clang-15

Below's UI is quite laggy in debug builds. We recommend always building in release mode.

In the root of the repository:

cargo build --release
cargo test
