Latest Meson version supporting previous Python versions:
Meson is available onPyPI, so it can be installed withpip3 install meson. The exact command to type to install withpip can vary between systems, be sure to use the Python 3 version ofpip.
If you wish you can install it locally with the standard Python command:
python3-m pip install meson
For builds using Ninja, Ninja can be downloaded directly from NinjaGitHub release page or viaPyPI
python3-m pip install ninja
More on Installing Meson build can be found at thegetting meson page.
Meson can be run as aPython zip app. To generate the executable run the following command:
./packaging/create_zipapp.py --outfile meson.pyz --interpreter '/usr/bin/env python3' <source checkout>
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 calledmeson.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 calledmeson.py instead of plainmeson. 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>meson setup builddir
To compile, cd into your build directory and typeninja. To run unit tests, typeninja test.
More on running Meson build system commands can be found at therunning meson page or by typingmeson --help.
