Meson Wrap Database

This is a collection of projects that use Meson as their build system, or have a meson port maintained by the Meson team. They can be used as subproject to any Meson project that needs them as dependency.

How to test a wrap

Clone this repository locally, and set the wraps option with a comma separated list of wraps that needs to be built.

For example to test libjpeg-turbo and zlib:

meson setup builddir -Dwraps=libjpeg-turbo,zlib
meson compile -C builddir

How to contribute new wraps

• Write my-project.wrap file and add it in subprojects/ directory.

• If upstream project's build system is not Meson, a port can be added in subprojects/packagefiles/my-project/meson.build and patch_directory = my-subproject should be added into the wrap file. Note that the whole subprojects/packagefiles/my-project subtree will be copied onto the upstream's source tree, but it is generally not accepted to override upstream files.

• It is often easier to develop in subprojects/my-project directory and update packagefiles directory at the end. This can be done using tools/update-packagefiles.py script.

• Add your release information in releases.json. It is a dictionary where the key is the wrap name and the value is a dictionary containing with the following keys:

  • versions: Sorted list (newest first) of release tags in the format <upstream version>-<revision> where the revision starts at 1 and is incremented when a changed is made in the meson port.
  • dependency_names: (Optional) List of dependency names (e.g. pkg-config name such as glib-2.0) provided by the wrap. It must match information from wrap's [provide] section.
  • program_names: (Optional) List of program names (e.g. glib-compile-resources) provided by the wrap. It must match information from wrap's [provide] section.

• Configure CI in ci_config.json. It is a dictionary where the key is the wrap name and the value is a dictionary containing with the following keys:

  • build_options: (Optional) List of option=value strings that will be used to build the project on the CI.
  • debian_packages: (Optional) List of extra packages that will be installed on debian-like CI runners. Dependencies that can be provided by other wraps should not be added here because it's better to test that fallbacks works. When running tools/sanity_checks.py locally, this list will be printed but not installed.
  • brew_packages: (Optional) List of extra packages that will be installed on MacOS CI runners.
  • linux_only: (Optional) If set to true, indicates the wrap should be tested only on Linux CI.
  • fatal_warnings: (Optional) If set to false removes --fatal-meson-warning. Use this only when there is no other way to fix the warning.

• Test locally by running tools/sanity_checks.py script. It will be executed on the CI and must always return success before merging any PR.

• Create Pull Request with your changes.

How to import one of those wraps into my project

Run meson wrap install <name> on the top source dir of your project. It will install subprojects/<name>.wrap file used by Meson to download the dependency.
