This is a work-in-progress implementation of a EGL External Platform library to add client-side Wayland support to EGL on top of EGLDevice and EGLStream families of extensions.
This library implements an EGL External Platform interface to work along with EGL drivers that support the external platform mechanism. More information about EGL External platforms and the interface can be found at:
https://github.com/NVIDIA/eglexternalplatform
This library build-depends on:
-
EGL headers
https://www.khronos.org/registry/EGL/ -
Wayland libraries & protocols
https://wayland.freedesktop.org/ -
EGL External Platform interface
https://github.com/NVIDIA/eglexternalplatform
To build, run:
./autogen.sh
make
To install, run:
make install
You can also use meson build system to build and install:
meson builddir
cd builddir
ninja
ninja install
Notes:
The NVIDIA EGL driver uses a JSON-based loader to load all EGL External platforms available on the system.
If this library is not installed as part of a NVIDIA driver installation, a JSON configuration file must be manually added in order to make the library work with the NVIDIA driver.
The default EGL External platform JSON configuration directory is:
/usr/share/egl/egl_external_platform.d/
Thanks to James Jones for the original implementation of the Wayland EGL platform.
