这里有点奇怪，这个确切的配置用于构建就好了，但现在失败了。我的qt5图层中没有自定义bbappends，因此它应该只是meta-qt5的vanilla构建。
失败看起来像这样：
$ bitbake meta-toolchain-qt5

我对此的解读是，软件包管理器只期望软件包packagegroup-core-standalone-sdk-target-dbg packagegroup-core-standalone-sdk-target＆amp; package中的ascii字符。 packagegroup-qt5-toolchain-target并遇到超出范围的值（195 / 0xc3）。可能聪明的是期待错误的编码。如果这是正确的，如何为这些包的安装指定备用编码＆amp;我怎样才能确定正确的编码应该是什么？
我有点惊讶于这突然变成了一个问题，因为我的构建指向与之前的工作状态完全相同的来源 - 它可能完全不同。我遇到的唯一另一件事是我在构建工作和失败之间运行了apt-get更新，因此完全有可能其中一个构建工具的版本可能已更改。
如果我有任何关于如何进行的建议将非常感激，如果我能提供更多数据，请告诉我。

看起来它实际上并没有在任何与meta-qt5相关的包上失败，而是udev-cache应该来自oe-core中的udev配方。
如果您之前已经构建了相同的源而没有问题，我会尝试强制重建udev包，只是为了排除某个文件意外地被破坏。
再次尝试bitbake -c cleansstate udev然后bitbake meta-toolchain-qt5。
