Prerequisites

C++ toolchain

You need a C++ compiler that supports C++17. Clang 10+ and GCC 10+ both work. On macOS, the Xcode command-line tools provide Clang:

xcode-select --install

On Debian/Ubuntu:

sudo apt install build-essential

CMake 3.15 or later. Check with:

cmake --version

Conan 2 manages all C++ dependencies (protobuf, gflags, leveldb, brpc, etc.). Install it with Homebrew on macOS:

brew install conan

Or with pip on Linux:

pip install conan

If you have never used Conan on this machine, detect a default profile:

conan profile detect

Check the version:

conan --version   # must be 2.x

The docs site is built with Docusaurus and requires Node.js 18+ and npm:

node --version
npm --version

If you are only building the C++ code, you do not need Node.

A quick sanity check that the build tools are in place:

cmake --version && c++ --version && conan --version

If all three commands print version info, you are ready to build. Next step: Build and test.
