我从制造商那里获得了一个基本的工作 yocto 图像，并且想将 sqlite 添加到该图像中。为了做到这一点，我浏览了 openembedded 上的开源层，发现了这些食谱。
我继续复制可以在上面的网页上找到的配方和 inc 文件，并将其添加到我自己的单独层内的制造商的 yocto 版本中。我必须更新 sqlite 配方的语法，即用“_”替换所有“：”。例如我改变了：
PACKAGECONFIG:class-native ?= "fts4 fts5 rtree dyn_ext"
至：
PACKAGECONFIG_class-native ?= "fts4 fts5 rtree dyn_ext"
显然这是因为带冒号的语法属于新的 Yocto 语法，而下划线是旧的语法。制造商的配方中除了下划线之外从不包含冒号。
然后我尝试构建图像并收到大量如下错误：

有人有什么建议吗？
我尝试通过谷歌搜索来了解此错误的含义或导致此错误的原因。到目前为止还没有成功。
我有时也会遇到这个错误，它来自（我使用 yocto dunfell 所以 bitbake 1.46）这里
评论说这是一个错误，但我还没有找到明确的方法来重现它。不管怎样，它似乎没有那么影响，只需重新运行你的任务就应该没问题。
我在 yocot bitbake 文件中也有这个“...在覆盖和未覆盖的情况下”。 我的解决方案是更改开源补丁文件名中的数字。 文件名中的原始编号重复，例如0001-xxxx，0001-xxxx...也许do_package都在这两个补丁中。我将 1 更改为 0002-xxx 并修改 bbappend 以重新定位补丁。错误已解决。
我发现当我构建 yocto 项目并且该过程被外部中断或发生系统冻结时会发生这种情况。我还没有确定构建执行和崩溃的确切时间，但在我长达一年的 Kirkstone/Mickledore yocto 项目开发过程中多次看到这种情况发生。
要修复此问题，我只需重新运行构建过程即可。
请注意，通常我可以中断 (CTRL-C) 构建过程，而不会遇到“setscene 任务”问题。
