Mac电脑编译安卓10代码时报错

遇到的现象和发生背景，请写出第一个错误信息

使用make -j4命令时报错，对比了29.txt和libs.txt无差异，可能是diff: unrecognized option `--old-line-format=Removed %L'这个原因导致的，这个如何处理？

【以下回答由 GPT 生成】

问题分析： 根据报错信息，是因为diff命令不识别'--old-line-format'这个选项导致的。可能是由于使用的是Mac电脑，与Linux的diff命令存在差异导致的。

解决方案： 一种解决方案是通过安装GNU diff来替代Mac电脑自带的diff命令，GNU diff支持'--old-line-format'这个选项。 以下是具体步骤：

1. 确认是否已安装Homebrew（Mac上一个常用的包管理工具）。运行以下命令检查是否已安装Homebrew：

brew --version

如果没有安装Homebrew，根据官方文档安装：https://brew.sh/index_zh-cn

1. 使用Homebrew安装GNU diff。运行以下命令进行安装：

brew install diffutils

1. 修改编译脚本中的diff命令，将diff命令路径改为/usr/local/bin/gdiff，或者在终端中运行以下命令将diff命令指向GNU diff：

brew link diffutils

1. 重新运行编译命令，查看是否解决了报错：

make -j4

如果仍然存在其他报错，请提供报错信息以便进一步分析。
