问：
我正在使用 M13.2.1 pro 芯片在 macOS 1 中编译 chrome，当我运行此命令时，显示错误：

如何解决这个问题？我已经阅读了文档 https://chromium.googlesource.com/chromium/src/+/main/docs/mac_arm64.md 并且已经添加了文件。Xcode 版本是 。这是 args.gn 文件内容：target_cpu = "arm64"chromium/src/out/Default/args.gnVersion 14.3 (14E222b)
➜ Default git:(64ca7395b4) cat args.gn
# Set build arguments here. See `gn help buildargs`.
target_cpu = "arm64"

我看到发布的编译器命令行包含参数，也就是说，它想要编译一个可以在 MacOS 10.13（又名“High Sierra”）或更高版本下运行的可执行文件。-mmacos-version-min=10.13
此类程序可能无法合法调用仅在 MacOS 13.0（又名“Ventura”）或更高版本中可用的函数，因此会出现错误消息。
我建议您在 build-config 中找到指定的位置，并将其更改为类似的东西;或者，如果你确实需要你的程序可以在High Sierra下运行，那么你需要重写代码，这样它就不会调用10.13 / High Sierra版本操作系统不支持的任何函数。 其他一些代码路径被调用;但我对这种技术不是很熟悉，所以与其尝试描述它，不如只提供一个指向 Apple 文档的链接）-mmacos-version-min=10.13-mmacos-version-min=13.0

有两种方法： 第一个是添加 gn arg
treat_warnings_as_errors = true;
第二个是：
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wunguarded-availability-new"
// put your error code here
#pragma clang diagnostic pop

我今天在 macOS 13.4.1 上尝试编译 Chromium 时遇到了同样的错误。我最终对 中的默认 clang 编译器参数进行了小幅修改，从而成功完成了构建。build/config/compiler/BUILD.gn

链接到 Chromium 的 GitHub 镜像上的行：https://github.com/chromium/chromium/blob/4378d583b52c891b6429ae704bf5ecb252375997/build/config/compiler/BUILD.gn#L1742C6-L1742C6
通常，修复可用性警告是值得的，但对于我的用例，我为自己构建了 Chromium，而不打算在早期版本的 macOS 上将其分发给其他人。
