有什么办法可以解决这个问题吗？
关于之前的消息，我的 gitlab-runner 也调用了 oom-killer。
这么大的内存怎么可能？
Yocto 构建 RAM 消耗还取决于 CPU 核心数量。
作为解决方法，如果不需要，您可以从构建中省略
qtwebengineBB_NUMBER_THREADSPARALLEL_MAKElocal.conf$ BB_NUMBER_THREADS=1 bitbake your-image
通过限制编译器线程的数量，您可以适应您的 RAM 量。
您可以先尝试构建qtwebengine。然后将其缓存并构建整个图像。如果示例 qtwebengine 仍未运行，则限制线程以使其运行。您可以用您的形象来提高这些。
bitbake qtwebengine
bitbake your-image
通常 Yocto 建议每个虚拟核心使用超过 2GB 的内存。所以 32GB 对于开启 smt 的 8 核处理器来说是不错的。这很大程度上取决于您正在构建什么。
假设您已解决问题。我遇到了类似的问题，但它处于
nodejs所以我的解决方法是执行以下操作之一：
