我正在尝试从AOSP android 7.1.2 源代码构建 adb并使用 g++ (Ubuntu 5.4.0-6ubuntu1~16.04.5) 5.4.0 20160609 编译它，方法是慢慢添加基于Android.mk和在我去的时候修复编译器的抱怨。到目前为止，我得到了以下命令，但我不确定如何解决以下错误：

似乎_Nonnull和_Nullable在./adb/sysdeps.h中定义

58 // Clang-only nullability specifiers
57 #define _Nonnull
59 #define _Nullable

似乎 AOSP 7.1.2 附带 gcc 4.8。另外，我注意到-Wexit-time-destructors似乎不是我正在使用的 g++ 的一部分，也不是-compatibility_version

_Nonnull并且_Nullable是Clang 的私有关键字。由于条件，没有执行 2 行声明#ifdef _WIN32。

因此，为了g++在 Linux 上使用它进行编译，请将这两个声明放到它们在全球生效的其他地方。
