在yocto中建立元虚拟化层
[英]Building meta-virtualization layer in yocto
问题描述
I am trying to add the meta-virtualization layer in my yocto project. 
我正在尝试在yocto项目中添加元虚拟化层。 The layer depends on openembedded-core and multiple layers provided by meta-openembedded. 该层取决于openembedded-core和meta-openembedded提供的多层。 Following is the structure of my bblayers.conf file after adding the meta-virtualization layer and it's dependencies. 添加元虚拟化层及其依存关系后，以下是bblayers.conf文件的结构。
BBLAYERS ?= " \
/home/mshehery/Downloads/git/Yocto/poky/meta \
/home/mshehery/Downloads/git/Yocto/poky/meta-yocto \
/home/mshehery/Downloads/git/Yocto/poky/meta-yocto-bsp \
/home/mshehery/Downloads/git/Yocto/poky/meta-oe \
/home/mshehery/Downloads/git/Yocto/poky/meta-virtualization \
/home/mshehery/Downloads/git/Yocto/poky/meta-networking \
/home/mshehery/Downloads/git/Yocto/poky/meta-filesystems \
/home/mshehery/Downloads/git/Yocto/poky/meta-python \
"
However, when I try to build docker present in the meta-virtualization layer, I encounter the following error 但是，当我尝试构建存在于元虚拟化层中的泊坞窗时，遇到以下错误

If I am not wrong, the current versions of the yocto project use openembedded as their build system. 如果我没看错，则yocto项目的当前版本将openembedded用作其构建系统。 So, is there any need to integrate the openembedded-core into my yocto project to add the meta-virtualization layer, or is it already present in the yocto project by default? 那么，有没有必要将openembedded-core集成到我的yocto项目中以添加元虚拟化层，或者默认情况下它已经存在于yocto项目中？

Short summary of the discussion: 讨论摘要：
Use the same release branch for all your layers (unless you really know what you do.
对所有图层使用相同的发布分支（除非您真的知道自己在做什么。 Check that all your layers are activated in
bblayers.conf.检查是否在bblayers.conf中激活了所有图层。
