meson

What it is and what it does

Meson is a next-generation build system that reads declarative build definitions from meson.build files and generates build instructions. It emphasizes clarity and speed by using a modern configuration language and delegating execution to external build backends. The package itself is a Python tool that processes your build configuration and produces the necessary build artifacts.

You use Meson by creating a meson.build file in your project root that describes your targets and build options, then run `meson setup builddir` to generate a build directory. The system supports multiple operating systems including Linux, macOS, Windows, and BSD. It is classified as Production/Stable and has been actively maintained since its first release in 2016.

Use it for:

• Set up build systems for projects that need to work identically across Linux, macOS, Windows, and BSD.
• Define and run unit tests as part of the build process after compilation.
• Manage projects with complex build configurations using a declarative, modern syntax.
• Automate build setup in continuous integration pipelines where reproducible builds are critical.
• Configure builds for projects requiring Python 3.10 or newer environments.

AI-flagged interpretation of the facts on this page — verify before relying

Meson is a build system that reads declarative meson.build configuration files and generates build files to orchestrate compilation and testing of projects.

Yes. Meson is production-stable, actively maintained, permissively licensed under Apache License, Version 2.0, and has no known security vulnerabilities. Install it if you need a build system for projects targeting Python 3.10 or newer. The main prerequisite is ensuring Python 3.10+ is available in your environment.

Install

meson on PyPI

pip install meson

uv add meson

poetry add meson

Installing meson

Before you install

Installation is straightforward with no runtime dependencies. The project is actively maintained with a recent release (4 days since last release) and strong community engagement (6603 GitHub stars).

License in practice

Licensed under Apache License, Version 2.0 (permissive), which allows commercial and private use with minimal restrictions.

Quickstart

pip install meson

# In your project directory with meson.build:
meson setup builddir
cd builddir
meson compile

Requires Python 3.10 or newer. Requires version 1.8.2 or newer of an external build backend to execute generated build files.

Verify before relying

• Whether Meson's learning curve or configuration complexity is suitable for small projects versus large codebases.
• Performance characteristics compared to other build systems in typical project scenarios.
• Which languages and project types Meson is optimized for beyond the general build orchestration role.
