Meson

The Meson() build helper is intended to be used in the build() and package() methods, to call Meson commands automatically.

from conan import ConanFile
from conan.tools.meson import Meson

class PkgConan(ConanFile):

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

    def package(self):
        meson = Meson(self)
        meson.install()

Reference

class Meson(conanfile)

This class calls Meson commands when a package is being built. Notice that this one should be used together with the MesonToolchain generator.

Parameters:

conanfile – < ConanFile object > The current recipe object. Always use self.

configure(reconfigure=False)

Runs meson setup [FILE] "BUILD_FOLDER" "SOURCE_FOLDER" [-Dprefix=/] command, where FILE could be --native-file conan_meson_native.ini (if native builds) or --cross-file conan_meson_cross.ini (if cross builds).

Parameters:

reconfigure – bool value that adds --reconfigure param to the final command.

build(target=None)

Runs meson compile -C . -j[N_JOBS] [TARGET] in the build folder. You can specify N_JOBS through the configuration line tools.build:jobs=N_JOBS in your profile [conf] section.

Parameters:

target – str Specifies the target to be executed.

install()

Runs meson install -C "." --destdir in the build folder.

test()

Runs meson test -v -C "." in the build folder.

conf

The Meson build helper is affected by these [conf] variables:

• tools.meson.mesontoolchain:extra_machine_files=[<FILENAME>] configuration to add your machine files at the end of the command using the correct parameter depending on native or cross builds. See this Meson reference for more information.

• tools.compilation:verbosity which accepts one of quiet or verbose and sets the --verbose flag in Meson.build()

• tools.build:verbosity which accepts one of quiet or verbose and sets the --quiet flag in Meson.install()
