在NDK上编译protobuf-2.4.1代码版本（android-ndk-r8-windows）

Question

嗨，我试图在NDK版本上编译protobuf-2.4.1代码（android-ndk-r8-windows。）

我已经设置如下：

PREBUILT=/cygdrive/d/D_Drive/Project/Pr/CCore/Code/NDK/android-ndk-r8-windows/android-ndk-r8/toolchains/arm-linux-androideabi-4.4.3 

PLATFORM=/cygdrive/d/D_Drive/Project/Pr/CCore/Code/NDK/android-ndk-r8-windows/android-ndk-r8/platforms/android-4/arch-arm/ 

export CC="/cygdrive/d/D_Drive/Project/Pr/CCore/Code/NDK/android-ndk-r8-windows/android-ndk-r8/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin/arm-linux-androideabi-gcc" 

export CFLAGS="-fPIC -DANDROID -nostdlib" 

export ANDROID_ROOT="/cygdrive/d/D_Drive/Project/Pr/CCore/Code/NDK/android-ndk-r8-windows/android-ndk-r8" 

export LDFLAGS="-Wl,-rpath-link=$ANDROID_ROOT/platforms/android-4/arch-arm/usr/lib/ -L$ANDROID_ROOT/platforms/android-4/arch-arm/usr/lib/" 

export CPPFLAGS="-I$ANDROID_ROOT/platforms/android-4/arch-arm/usr/include/" 

CPPFLAGS="-I$ANDROID_ROOT/platforms/android-4/arch-arm/usr/include/" 
CPPFLAGS=$CPPFLAGS:"-I$ANDROID_ROOT/sources/cxx-stl/gnu-libstdc++/include/" 
export CPPFLAGS 

./configure --host=arm-eabi 

我得到以下问题，而这样做NDK建造：

Answer 1

这是NDK的文档：

C++ STL支持：

独立工具链还附带GNU libstdC++库的副本，该库提供了C++标准模板库的实现。要使用它，您需要链接到合适的库：

使用-lstdC++链接到静态库版本。这可确保所有必需的C++ STL代码都包含在最终的二进制文件中。如果您只生成单个共享库或可执行文件，这非常理想。 这是推荐的方式。

• 使用-lgnustl_shared兑共享库版本链接。如果您有几个相关的共享库或可执行文件需要在运行时在同一个地址空间中运行，则这是必需的（某些全局变量需要唯一定义，如果您将静态libstdC++链接到每个可执行文件，这是不可能的） 。

  如果使用此选项，则需要确保将libgnustl_shared.so也复制到设备上，以便代码正确加载。该文件是：

$ TOOLCHAIN/ARM-Linux的androideabi/lib目录/ ARM的工具链

$ TOOLCHAIN/i686的，Android的Linux的/ lib目录/为86人。

$ TOOLCHAIN/mipsel体系-Linux的Android的/ lib目录/ MIPS的工具链

重要提示：GNU的libstdC++是GPLv3的许可下一个链接例外。请参阅以下网址了解详细信息：

 http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt01ch01s02.html 

如果你不能与它的要求符合，即你不能重新分配共享库，在项目中不使用它。

GNU libstdC++的共享版本不叫libstdC++的原因是因为这会在运行时与系统自己的最小C++运行时冲突，这是/system/lib/libstdc++.so。这为GNU ELF库强制实施一个新名称。这对静态库不是问题。

Answer 2

我有同样的错误。

要解决该问题，您必须在您的Application.mk文件中有APP_STL := gnustl_static。
