Building Weston
===============
Weston is built using autotools, with `autogen.sh` and `make`. It often depends
Weston is built using [Meson](https://mesonbuild.com/). Weston often depends
on the current release versions of
[Wayland](https://gitlab.freedesktop.org/wayland/wayland) and
[wayland-protocols](https://cgit.freedesktop.org/wayland/wayland-protocols).
If necessary, the latest Meson can be installed as a user with:
$ pip3 install --user meson
Weston's Meson build does not do autodetection and it defaults to all
features enabled, which means you likely hit missing dependencies on the first
try. If a dependency is avoidable through a build option, the error message
should tell you what option can be used to avoid it. You may need to disable
several features if you want to avoid certain dependencies.
$ git clone https://gitlab.freedesktop.org/wayland/weston.git
$ cd weston
$ meson build/ --prefix=...
$ ninja -C build/ install
$ cd ..
The `meson` command populates the build directory. This step can
fail due to missing dependencies. Any build options you want can be added on
that line, e.g. `meson build/ --prefix=... -Dsimple-dmabuf-drm=intel`.
All the build options can be found in the file
[meson_options.txt](meson_options.txt).
Once the build directory has been successfully populated, you can inspect the
configuration with `meson configure build/`. If you need to change an
option, you can do e.g.
`meson configure build/ -Dsimple-dmabuf-drm=intel`.
Every push to the Weston master repository and its forks is built using GitLab
CI. [Reading the configuration](.gitlab-ci.yml) may provide a useful example of
how to build and install Weston.
