yocto ERROR: Dependency "wayland-egl" not found

这个错误提示意味着在您的 Yocto 项目中缺少 wayland-egl 依赖项。您需要在您的 Yocto 配置文件中添加一个包含 wayland-egl 的层或者在您的配置文件中明确地将 wayland-egl 添加为依赖项。

如果您已经有了包含 wayland-egl 的层，那么您需要将该层添加到您的 Yocto 配置文件中。您可以使用 bitbake-layers 命令来添加一个层，例如：

$ bitbake-layers add-layer <path-to-layer>

其中 <path-to-layer> 是指向包含 wayland-egl 的层的路径。添加层之后，重新编译您的 Yocto 项目即可。

如果您无法找到包含 wayland-egl 的层，您可以尝试搜索您的 Yocto 发行版的软件仓库，或者在您的配置文件中手动添加 wayland-egl 依赖项。您可以在您的配置文件中添加类似以下的行：

DEPENDS += "wayland-egl"

然后重新编译您的 Yocto 项目即可。

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.

yocto sh: sudo: command not found

根据提供的引用内容，您遇到了一个"yocto sh: sudo: command not found"的错误。这个错误通常是因为在您的系统中没有安装sudo命令所致。sudo是一个用于以超级用户权限运行命令的工具。要解决这个问题，您可以按照以下步骤安装sudo命令：

1. 打开终端并运行以下命令以安装sudo：

$ apt-get install sudo

2. 输入您的密码以确认安装。

3. 安装完成后，您可以尝试再次运行您的yocto命令，应该不再出现"yocto sh: sudo: command not found"的错误。

请注意，安装sudo命令可能需要管理员权限。如果您没有管理员权限，请联系系统管理员或使用其他适用于您的系统的方法来获取sudo权限。
