Dylan Baker 9e3b3db705 backend/ninja: Fix cases where None is passed when unexpected When getting debug file arguments we can sometimes pass None, where a None is unexpected. This becomes a particular problem in the Cuda compiler, where the output will unconditionally be concatenated with a static string, resulting in an uncaught exception. This is really easy to spot once we annotate the functions in question, where a static type checker like mypy easily spots the issue. This commit adds those annotations, and then fixes the resulting error. Fixes: #12997		hace 2 días

README.md

Meson® is a project to create the best possible next-generation build system.

Status

Dependencies

Python (version 3.7 or newer)
Ninja (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, 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:

python3 -m pip install meson

For builds using Ninja, Ninja can be downloaded directly from Ninja GitHub release page or via PyPi

python3 -m pip install ninja

More on Installing Meson build can be found at the getting meson page.

Creating a standalone script

Meson can be run as a Python zip app. 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:

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 or by typing meson --help.

Contributing
