Meson® is a project to create the best possible next-generation build system. #### Status [![PyPI](https://img.shields.io/pypi/v/meson.svg)](https://pypi.python.org/pypi/meson) [![Travis](https://travis-ci.org/mesonbuild/meson.svg?branch=master)](https://travis-ci.org/mesonbuild/meson) [![Build Status](https://dev.azure.com/jussi0947/jussi/_apis/build/status/mesonbuild.meson)](https://dev.azure.com/jussi0947/jussi/_build/latest?definitionId=1) [![Codecov](https://codecov.io/gh/mesonbuild/meson/coverage.svg?branch=master)](https://codecov.io/gh/mesonbuild/meson/branch/master) [![Code Quality: Python](https://img.shields.io/lgtm/grade/python/g/mesonbuild/meson.svg?logo=lgtm&logoWidth=18)](https://lgtm.com/projects/g/mesonbuild/meson/context:python) [![Total Alerts](https://img.shields.io/lgtm/alerts/g/mesonbuild/meson.svg?logo=lgtm&logoWidth=18)](https://lgtm.com/projects/g/mesonbuild/meson/alerts) #### Dependencies - [Python](https://python.org) (version 3.5 or newer) - [Ninja](https://ninja-build.org) (version 1.5 or newer) #### Installing from source You can run Meson directly from a revision control checkout or an extracted tarball. If you wish you can install it locally with the standard Python command ```sh python3 -m pip install meson ``` Meson is also available from [PyPi](https://pypi.python.org/pypi/meson), so it can be installed with `pip3 install meson` (this does not require a source checkout, pip will download the package automatically). The exact command to type to install with Pip can vary between systems, be sure to use the Python 3 version of Pip. #### Running Meson requires that you have a source directory and a build directory and that these two are different. In your source root must exist a file called `meson.build`. To generate the build system run this command: `meson ` Depending on how you obtained Meson the command might also be called `meson.py` instead of plain `meson`. In the rest of this document we are going to use the latter form. You can omit either of the two directories, and Meson will substitute the current directory and autodetect what you mean. This allows you to do things like this: `cd source_root; mkdir builddir; cd builddir; meson ..` or `cd source_root; mkdir builddir; meson builddir` To compile, cd into your build directory and type `ninja`. To run unit tests, type `ninja test`. Install is the same but it can take an extra argument: `DESTDIR=/destdir/path ninja install` `DESTDIR` can be omitted. If you are installing to system directories, you may need to run this command with sudo. #### Contributing We love code contributions. See the [contribution page](https://mesonbuild.com/Contributing.html) on the web site for details. #### IRC The irc channel for Meson is `#mesonbuild` over at Freenode. You can use [FreeNode's official webchat][meson_irc] to connect to this channel.
