Meson plugin¶

The Meson plugin configures projects using Meson and builds them using Ninja.

After a successful build, this plugin will install the generated binaries in $CRAFT_PART_INSTALL.

Keys¶

This plugin provides the following unique keys.

meson_parameters¶

Type: list of strings Default: []

Parameters to configure the project. See the reference to the setup command for a list of valid options.

Dependencies¶

The plugin needs the meson executable to configure the project, and the ninja executable to build it. These are not installed by default but can typically be provisioned via build-packages or build-snaps.

Another alternative is to define another part with the name meson-deps, and declare that the part using the meson plugin comes after the meson-deps part through the after key. In this case, the plugin will assume that this new part will stage the meson and ninja executables to be used in the build step. This can be useful, for example, in cases where specific, unreleased versions of the tools are desired but unavailable as a snap or an Ubuntu package.

How it works¶

During the build step the plugin performs the following actions:

Run meson in the build directory referring to the pulled source directory (this plugin runs an out of tree build). The project is configured with any meson-parameters that might have been set;
ninja is run to build the source;
ninja install is called with DESTDIR set to $CRAFT_PART_INSTALL.

Examples¶

The following snippet declares a part using the meson plugin. It uses --buildtype=release to generate optimised release binaries with no debug symbols. The declaration of the meson package as a build-package will also pull in the ninja-build package as a dependency.

parts:
  my-meson-part:
    source: .
    plugin: meson
    build-packages:
      - meson
    meson-parameters:
      - "--buildtype=release"
