将 OSX 从 12.1 升级到 12.2.1 破坏了我的开发环境

Question

我在从 12.1 轻微 OSX 升级到 12.2.1 后编译软件时看到各种错误和警告。

另一组与升级相关的错误是这些：

/usr/local/include/stdlib.h:355:21: warning: pointer is missing a nullability type specifier (_Nonnull, _Nullable, or _Null_unspecified) [-Wnullability-completeness]
         strtoq(const char *__str, char **__endptr, int __base);
                           ^
/usr/local/include/stdlib.h:355:21: note: insert '_Nullable' if the pointer may be null
         strtoq(const char *__str, char **__endptr, int __base);
                           ^
                             _Nullable

         strtoq(const char *__str, char **__endptr, int __base);

我看过很多与此相关的帖子，我试过以下方法：

我一开始并没有使用 Xcode，但我还是尝试下载了它，看看它是否有帮助。没有。
多次删除并重新安装 CommandLineTools
找到旧版本的 SDK 并尝试用它替换当前的 SDK（即 MaxOSX11.1.sdk），因为 11.3，12.x 也不起作用。

xcrun --show-sdk-path                  
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk

ls -l /Library/Developer/CommandLineTools/SDKs
total 0
lrwxr-xr-x  1 root  wheel   14 Feb 20 13:26 MacOSX.sdk -> MacOSX12.1.sdk
drwxr-xr-x  7 root  wheel  224 Feb 20 13:26 MacOSX11.3.sdk/
lrwxr-xr-x  1 root  wheel   14 Feb 20 13:25 MacOSX11.sdk -> MacOSX11.3.sdk
drwxr-xr-x  7 root  wheel  224 Feb 20 13:27 MacOSX12.1.sdk/
lrwxr-xr-x  1 root  wheel   14 Feb 20 13:25 MacOSX12.sdk -> MacOSX12.1.sdk

运行xcode-select -s /Library/Developer/CommandLineTools多次
尝试创建手动符号链接以使 /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk 指向我系统上的不同 SDK，但没有成功。

我没有想法（除了硬重置我的 mac，我想避免这种情况）。

这里有一些希望有用的信息：

clang -cc1 version 13.1.6 (clang-1316.0.20.6) default target x86_64-apple-darwin21.3.0

 /Library/Developer/CommandLineTools/usr/include
 /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks (framework directory)
End of search list.

我所有的东西都备份到 github 但我真的很想避免硬重置。

所以经过更多的挖掘，我最终重命名了一些在 /usr/local/include 中引用的 std 库 h 文件，我的项目又恢复了工作。

重命名了以下文件：

/usr/local/include/_stdio.h -> /usr/local/include/__stdio.h
/usr/local/include/stdio.h -> /usr/local/include/stdio_old.h
/usr/local/include/AvailabilityMacros.h -> /usr/local/include/_AvailabilityMacros.h
/usr/local/include/stdlib.h -> /usr/local/include/_stdlib.h
/usr/local/include/pthread.h -> /usr/local/include/_pthread.h

隐藏这些文件后，编译器正在搜索另一个工作目录headers，项目再次编译没有问题。
