在 yocto 中构建元虚拟化层

Question

我正在尝试在我的 yocto 项目中添加元虚拟化层。该层依赖于 openembedded-core 和 meta-openembedded 提供的多层。以下是添加元虚拟化层及其依赖项后我的 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 \
"

但是，当我尝试在元虚拟化层中构建 docker 时，遇到以下错误

如果我没记错的话，yocto 项目的当前版本使用 openembedded 作为他们的构建系统。那么，是否需要将 openembedded-core 集成到我的 yocto 项目中以添加元虚拟化层，或者它是否已经默认存在于 yocto 项目中？

Answer 1

讨论的简短摘要：

对所有层使用相同的发布分支（除非你真的知道你在做什么。
检查您的所有图层是否在 bblayers.conf 中激活。
