| Meson® is a project to create the best possible next-generation |
| build system. |
| |
| #### Status |
| |
| [](https://pypi.python.org/pypi/meson) |

| |
| #### Dependencies |
| |
| - [Python](https://python.org) (version 3.7 or newer) |
| - [Ninja](https://ninja-build.org) (version 1.8.2 or newer) |

| Latest Meson version supporting previous Python versions: |
| - Python 3.6: **0.61.5** |
| - Python 3.5: **0.56.2** |
| - Python 3.4: **0.45.1** |
| |
| #### 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' <source checkout> |
| |
| #### 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 <source directory> <build directory>` |
| |
| 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 <source root> |
| 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`. |
