A Wayland compositor written in Kotlin.
This is a work in progress and not ready for day to day use, however certain features like client movement and render output on X are considered ready.
This compositor was originally written in Java. The latest Java commit can still be found here
Not available yet.
Prerequisites:
- gradle
- cmake
- docker (optional, needed for build-in cross compilation)
Run gradle build in the root of the project. Westford is still under heavy
development, so occasionally tests might fail. If this is the case you can run the build
with gradle build -x test.
To cross compile for a specific architecture, set the corresponding arch variable in the gradle build command. Available profiles are:
| Architecture | arch |
|---|---|
| aarch64 | linux-aarch64 |
| armv7hf | linux-armv7hf |
| armv7sf | linux-armv7sf |
| armv6hf | linux-armv6hf |
| x86_64 | linux-x86_64 |
| i686 | linux-i686 |
| all of above | all |
So if we were to build for armv7hf, our build command would becomes gradle build -x test -Parch=linux-armv7hf.
This will trigger a cross compilation inside a cleanly isolated docker container.
If no profile is selected, the gradle build will default to the native profile, which corresponds to
the architecture that you're currently building on, without the use of docker.
Westford can be launched using different back-ends and configurations. These live as separate projects
under launch
Currently the following back-ends exist:
launch.x11A back-end that outputs to a regular X11 window, one window per (virtual) screen. Ideal for quick testing.launch.drm.directUses the kernel's drm/kms system to directly output to the screen, without the use of X11. Root user only.launch.drm.indirectUses the kernel's drm/kms system to directly output to the screen, without the use of X11. All users. Uses setuid.
To create an runnable distribution, go into the launch.x11 folder. Type gradle installDist.
This will create an executable launch.x11 in build/install/launch.x11/bin
Next fire up some test clients from the Weston compositor (eg weston-terminal).
Make sure you use Weston 1.4 as more recent versions depend on xdg-shell which is not
yet implemented by Westford.
To configure the X11 back-end, open up X11PlatformConfigSimple.kt
found in westford/launch.x11/src/main/kotlin/org/westford/compositor/launch/x11 and adjust as required.
//TODO
The following native libraries are expected, depending on the features used:
- libc (core)
- pixman-1 (core)
- EGL (core)
- GLESv2 (core)
- libdrm (drm)
- libudev (drm)
- libinput (drm)
- X11 (x11)
- xcb (x11)
- X11-xcb (x11)
- xkbcommon (core)
- xkbcommon-x11 (x11)
- linux (core)
