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

Question

大家好，我正在尝试在 NDK 版本 (android-ndk-r8-windows) 上编译 protobuf-2.4.1 代码。

我设置如下:

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

我在进行 NDK 构建时遇到以下问题:

Answer 1

这是来自 NDK 文档:

C++ STL 支持:

独立工具链还附带了 GNU libstdc++ 库的副本，它提供了 C++ 标准模板库的实现。但是，要使用它，您需要链接到适当的库:

使用 -lstdc++ 链接到static 库版本。这可确保所有必需的 C++ STL 代码都包含在您的最终二进制文件中。如果您只生成一个共享库或可执行文件，这是理想的选择。这是推荐的方法。

• 使用 -lgnuSTL_shared 链接到共享 库版本。如果您有多个相关的共享库或可执行文件需要在运行时在同一地址空间中运行，则这是必需的(一些全局变量需要唯一定义，如果将静态 libstdc++ 链接到每个可执行文件，这是不可能的) .

  如果您使用此选项，您需要确保 libgnuSTL_shared.so 也被复制到您的设备，以便您的代码正确加载。文件位于:

用于 ARM 工具链的 $TOOLCHAIN/arm-linux-androideabi/lib/

$TOOLCHAIN/i686-android-linux/lib/用于 x86。

$TOOLCHAIN/mipsel-linux-android/lib/用于 MIPS 工具链

重要提示:GNU libstdc++ 在 GPLv3 下获得许可，但有一个链接异常(exception)。有关详细信息，请参阅以下 URL:

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

如果您不能遵守它的要求，即您不能重新分发共享库，请不要在您的项目中使用它。

GNU libstdc++ 的共享版本不称为 libstdc++.so 的原因是因为这会在运行时与系统自己的最小 C++ 运行时发生冲突，即/system/lib/libstdc++.so。这为 GNU ELF 库强制使用了一个新名称。这对静态库来说不是问题。
