本文详细介绍了Android NDK中支持的四种C++运行时库：libc++.so，libstdc++.so，libgnustl_shared.so和libc++_shared.so。包括它们的特点、适用场景及编译选项，如C++11标准、异常和RTTI支持。

android NDK c++ library support

--------------------------------------------

1. libc++.so：

libc++ on Mac OS X or FreeBSD

官方链接：https://libcxx.llvm.org/

2. libstdc++.so：

The minimal system C++ runtime library and the default runtime when using ndk-build or the experimental Gradle plugin.

The shared object library for this runtime, libstdc++.so, is an Android-specific implementation of a minimal C++ runtime. It is not the same as the GNU libstdc++ runtime library.

注：不包含标准模板库以及string类型

3. libgnustl_shared.so

The GNU STL (shared library).

4. libc++_shared.so

The LLVM libc++ runtime (shared library)

GNU STL runtime

This runtime is the GNU Standard C++ Library, (libstdc++-v3). Its shared library file is named libgnustl_shared.so. compiles with -std=gnu++11.

libc++ runtime:

This runtime is an Android port of LLVM libc++. Its shared library file is named libc++_shared.so.

By default, this runtime compiles with -std=c++11. As with GNU libstdc++, you need to explicitly turn on exceptions or RTTI support. For information on how to do this, see C++ Exceptions and RTTI.
