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.
Using Wayland-EGL Failed to load shell integration kwayland-shell
这个错误通常是因为缺少KWayland库导致的。KWayland是一个提供与Wayland协议交互的Qt库。如果你正在使用的是KDE桌面环境,那么你需要安装kwayland-integration包。
你可以尝试在终端中运行以下命令来安装该包:
```
sudo apt-get install kwayland-integration
```
如果你不是在KDE桌面环境下使用Wayland,那么你可能需要安装其他相关的库才能解决这个问题。你可以尝试通过搜索引擎找到适合你使用的库。
