Meson® is a project to create the best possible next-generation build system. #### Status [](https://pypi.python.org/pypi/meson) [](https://dev.azure.com/jussi0947/jussi/_build/latest?definitionId=1) [](https://codecov.io/gh/mesonbuild/meson/branch/master) #### Dependencies - [Python](https://python.org) (version 3.7 or newer) - [Ninja](https://ninja-build.org) (version 1.8.2 or newer) #### Installing from source Meson is available on [PyPi](https://pypi.python.org/pypi/meson), so it can be installed with `pip3 install meson`. The exact command to type to install with `pip` can vary between systems, be sure to use the Python 3 version of `pip`. If you wish you can install it locally with the standard Python command: ```console python3 -m pip install meson ``` For builds using Ninja, Ninja can be downloaded directly from Ninja [GitHub release page](https://github.com/ninja-build/ninja/releases) or via [PyPi](https://pypi.python.org/pypi/ninja) ```console python3 -m pip install ninja ``` More on Installing Meson build can be found at the [getting meson page](https://mesonbuild.com/Getting-meson.html). #### Creating a standalone script Meson can be run as a [Python zip app](https://docs.python.org/3/library/zipapp.html). To generate the executable run the following command: ./packaging/create_zipapp.py --outfile meson.pyz --interpreter '/usr/bin/env python3' #### 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 setup ` 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: ```console cd meson setup builddir ``` To compile, cd into your build directory and type `ninja`. To run unit tests, type `ninja test`. More on running Meson build system commands can be found at the [running meson page](https://mesonbuild.com/Running-Meson.html) or by typing `meson --help`. #### Contributing We love code contributions. See the [contribution page](https://mesonbuild.com/Contributing.html) on the website for details. #### IRC The channel to use is `#mesonbuild` either via Matrix ([web interface][matrix_web]) or [OFTC IRC][oftc_irc].
