Dependencies

Package	Min Version	Purpose
CMake	3.25	Build system
Ninja	1.11	Build backend
Clang	17	C++23 compiler
liburing	2.4	io_uring API
libsodium	1.0.18	Curve25519, XSalsa20
libspdlog	1.12	Logging
OpenSSL	3.0	TLS, kTLS support

On Debian/Ubuntu:

  liburing-dev libsodium-dev libspdlog-dev libssl-dev

CMake Presets

# Release (default)
cmake -B build -G Ninja -DCMAKE_BUILD_TYPE=Release
cmake --build build -j$(nproc)

# Debug (ASAN + assertions)
cmake -B build-debug -G Ninja \
  -DCMAKE_BUILD_TYPE=Debug
cmake --build build-debug -j$(nproc)

Cross-Compile for ARM64

sudo apt install gcc-aarch64-linux-gnu \
  g++-aarch64-linux-gnu

cmake -B build-arm64 -G Ninja \
  -DCMAKE_BUILD_TYPE=Release \
  -DCMAKE_SYSTEM_NAME=Linux \
  -DCMAKE_SYSTEM_PROCESSOR=aarch64 \
  -DCMAKE_C_COMPILER=aarch64-linux-gnu-gcc \
  -DCMAKE_CXX_COMPILER=aarch64-linux-gnu-g++

cmake --build build-arm64 -j$(nproc)

Running Tests

cd build && ctest --output-on-failure

Tests require a kernel with io_uring support (5.11+). Some kTLS tests require 5.19+.
