AOSP 构建失败 - ckati 失败并显示：退出状态 1

Question

所以我一直致力于构建Android AOSP项目。我遵循官方文档中的指南（https://source.android.com/setup/build/downloading）。 经过几次尝试，我总是从终端得到以下错误堆栈跟踪。我正在尝试构建 'aosp_coral-userdebug'。我注意到的另一件事是，如果我使用菜单中的另一个组合，我还会收到另一种形式的 'ninja' 错误。 请帮忙！！！

12:09:31 You are building on a machine with 15.4GB of RAM
12:09:31 
12:09:31 The minimum required amount of free memory is around 16GB,
12:09:31 and even with that, some configurations may not work.
12:09:31 
12:09:31 If you run into segfaults or other errors, try reducing your
12:09:31 -j value.

Answer 1

此错误通常意味着由于没有剩余 RAM，构建过程被笔记本电脑中的操作系统终止。 您可以通过在错误发生后运行 dmesg 并在内核日志中查看您的进程已被终止来确认。

解决方案是：

1. 使用比当前使用的更小的 j 值运行 make，或者
2. 获取更多内存，或者
3. 添加交换空间（将用作虚拟内存的磁盘部分）
