yocto编译wayland-egl

To compile Wayland-EGL in Yocto, you can follow these steps:

1. Add the necessary layers to your Yocto build. This may include the meta-openembedded layer, which contains the recipes for Wayland and other related packages.

2. Configure your build to include the Wayland-EGL packages. You can do this by adding the following lines to your local.conf file:

IMAGE_INSTALL_append = " wayland-protocols"
IMAGE_INSTALL_append = " wayland-egl"

This will ensure that the Wayland-Protocols and Wayland-EGL packages are included in your Yocto image.

3. Build your Yocto image. You can do this by running the `bitbake` command with the name of your image, such as:

bitbake core-image-minimal

This will compile the necessary packages and dependencies, and generate a Yocto image that includes Wayland-EGL.

4. Configure your system to use Wayland-EGL as the default display server. You can do this by modifying the `weston.ini` file in your image's root filesystem. Add the following lines to the file:

[core]
modules=eglbackend.so,desktop-shell.so

[shell]
background-image=/usr/share/backgrounds/gnome/Aqua.jpg
panel-location=none

This will configure the Weston compositor to use EGL as the backend for rendering graphics.

5. Boot your Yocto image and test Wayland-EGL. You can do this by running a Wayland client application, such as `weston-terminal` or `weston-flower`. If everything is configured correctly, you should see the application window rendered using EGL.

These are the basic steps for compiling Wayland-EGL in Yocto. However, the exact steps may vary depending on your specific Yocto setup and hardware platform. It's recommended to consult the Yocto documentation and community resources for more detailed instructions and troubleshooting tips.
