Meson is implemented in Python 3, and requires 3.6 or newer. If your operating system provides a package manager, you should install it with that. For platforms that don't have a package manager, you need to download it from Python's home page. See below for platform-specific Python3 quirks.
Meson releases can be downloaded from the GitHub release page, and
you can run
./meson.py from inside a release or the git repository
itself without doing anything special.
On Windows, if you did not install Python with the installer options
that make Python scripts executable, you will have to run
python /path/to/meson.py, where
python is Python 3.6 or newer.
The newest development code can be obtained directly from Git, and we strive to ensure that it will always be working and usable. All commits go through a pull-request process that runs CI and tests several platforms.
Installing Meson with pip
Meson is available in the Python Package Index and can be installed
sudo pip3 install meson which requires root and will install it
If you have downloaded a copy of the Meson sources already, you can
install it with
sudo pip3 install path/to/source/root/.
Alternatively, you can use
pip3 install --user meson which will
install it for your user and does not require any special
privileges. This will install the package in
~/.local/, so you will
have to add
~/.local/bin to your
sudo meson install
will be completely broken since the program will not be available to
root. Only use a user copy of Meson if you do not care about
installing projects as root.
Installing Meson and Ninja with the MSI installer
We provide an MSI installer on the GitHub release page that can be used to install both Meson and Ninja at once for Windows. It also contains an embedded copy of Python, so scripts that use the Python module and do not have any external dependencies will continue to work as expected.
Please note that this is a new feature, so bug reports are expected and welcome!
In the most common case, you will need the Ninja executable for
ninja backend, which is the default in Meson. This backend
can be used on all platforms and with all toolchains, including GCC,
Clang, Visual Studio, MinGW, ICC, ARMCC, etc.
You can use the version provided by your package manager if possible, otherwise download the binary executable from the Ninja project's release page.
If you will only use the Visual Studio backend (
generate Visual Studio solutions on Windows or the XCode backend
--backend=xcode) to generate XCode projects on macOS, you do not
Platform-specific install quirks
Windows Python3 quirks
When installing Python 3, it is highly recommended (but not required) that you select the installer options as follows:
With this, you will have
PATH, and you can
install Meson with pip. You will also be able to directly run
in any shell on Windows instead of having to run
py -3 with the full
path to the
MSYS2 Python3 quirks
If you are using MSYS2 on Windows as your development environment,
please make sure that you do not use the
msys/python package to
provide Python 3. Use either
mingw64/mingw-w64-x86_64-python3 depending on which MinGW target you
are building for.
