Question

我正在尝试从AOSP android 7.1.2 source code构建adb并使用g ++（Ubuntu 5.4.0-6ubuntu1~16.04.5）5.4.0 20160609编译它，通过基于缓慢添加包含和库 Android.mk 并随时修复编译器投诉。到目前为止，我接到了下面的命令，但我不确定如何解决下面的错误：

似乎 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g ++的一部分我用的也不是 -compatibility_version

Answer 1

_Nonnull和_Nullable是Clang's private keywords。由于条件#ifdef _WIN32，未执行两行声明。

因此，为了在Linux上使用g++进行编译，请将这两个声明放到它们在全局范围内生效的其他地方。

使用g ++构建adb时无法识别_Nonnull
