Meson

Warning

This is an experimental feature subject to breaking changes in future releases.

The Meson() build helper that works with the MesonToolchain is also experimental, and subject to breaking change in the future. It will evolve to adapt and complement the toolchain functionality.

The helper is intended to be used in the build() method, to call Meson commands automatically when a package is being built directly by Conan (create, install)

from conan.tools.meson import Meson

def build(self):
    meson = Meson(self)
    meson.configure()
    meson.build()

It supports the following methods:

constructor

def __init__(self, conanfile):

conanfile: the current recipe object. Always use self.

configure()

def configure(self):

Calls meson, with the given generator and passing either --native-file conan_meson_native.ini (native builds) or --cross-file conan_meson_cross.ini (cross builds).

build()

def build(self, target=None):

Calls the build system. Equivalent to meson compile -C . in the build folder.

Parameters:

target (Optional, Defaulted to None): Specifies the target to execute. The default all target will be built if None is specified.

install()

def install(self):

Installs development files (headers, libraries, etc.). Equivalent to run meson install -C . in the build folder.

test()

def test(self):

Runs project’s tests. Equivalent to running meson test -v -C . in the build folder..

conf

tools.build:jobs=10 argument for the --jobs parameter when running Ninja.
