linux - 在yocto中建立元虚拟化层

我正在尝试在yocto项目中添加元虚拟化层。该层取决于openembedded-core和meta-openembedded提供的多层。添加元虚拟化层及其依存关系后，以下是我的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，当我尝试构建存在于元虚拟化层中的 docker 时，遇到以下错误

如果我没看错，则yocto项目的当前版本将openembedded用作其构建系统。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？

最佳答案

讨论摘要:

对所有图层使用相同的发布分支(除非真的知道您的工作。)

检查是否已在bblayers.conf中激活了所有图层。
