Xavier Claessens 6a1732a29d nasm: Fallback to native compiler when cross compiling If nasm is not defined in cross file binaries we can fallback to build machine nasm. When cross compiling C code we need a different gcc binary for native and cross targets, e.g. `gcc` and `x86_64-w64-mingw32-gcc`. But when cross compiling NASM code the compiler is the same, it is the source code that has to be made for the target platform. We can thus use nasm from build machine's PATH to cross compile for Windows on Linux for example. The difference is the arguments Meson will pass when invoking nasm e.g. `-fwin64`. That is already handled by NasmCompiler class.		8 小時之前

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

We love code contributions. See the contribution page on the website for details.

IRC

The channel to use is #mesonbuild either via Matrix (web interface) or OFTC IRC.
