| Meson® is a project to create the best possible next-generation |
| build system. |
| |
| ####Build status |
| |
| [](https://travis-ci.org/mesonbuild/meson) [](https://ci.appveyor.com/project/jpakkane/meson) |
| |
| ####Dependencies |
| |
| - [Python](http://python.org) (version 3.4 or newer) |
| - [Ninja](https://ninja-build.org) |
| |
| ####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 distutils command `python3 setup.py install <your |
| options here>`. |
| |
| 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 very 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 <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: |
| |
| `cd source_root; mkdir build; cd build; meson ..` |
| |
| or |
| |
| `cd source_root; mkdir build; meson build` |
| |
| 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. |
