Android-对cryptopp的未定义引用

我在IOS上成功地编译和执行了Cryptopp，但我确实很难在android上运行它

在这里，我使用的是Cryptopp 5.6.3、NDK r10e和android studio 1.5，我可以通过NDK build成功构建libcryptopp.so，但在通过android studio进行重建时，它克服了许多错误，例如未定义对“vtable for Cryptopp:：AutoseedX917RNG”的引用

Android.mk中的

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := crypt_user
LOCAL_SRC_FILES := crypt_user.cpp
LOCAL_SHARED_LIBRARIES := cryptopp

include $(BUILD_SHARED_LIBRARY)

include $(CLEAR_VARS)

LOCAL_MODULE := cryptopp
LOCAL_SRC_FILES := $(TARGET_ARCH_ABI)/libcryptopp.so
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include

include $(PREBUILT_SHARED_LIBRARY)

APP_ABI := armeabi
APP_CPPFLAGS += -fexceptions -frtti
APP_STL := stlport_shared
#APP_STL := gnustl_shared

应用程序中的.mk

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := crypt_user
LOCAL_SRC_FILES := crypt_user.cpp
LOCAL_SHARED_LIBRARIES := cryptopp

include $(BUILD_SHARED_LIBRARY)

include $(CLEAR_VARS)

LOCAL_MODULE := cryptopp
LOCAL_SRC_FILES := $(TARGET_ARCH_ABI)/libcryptopp.so
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include

include $(PREBUILT_SHARED_LIBRARY)

APP_ABI := armeabi
APP_CPPFLAGS += -fexceptions -frtti
APP_STL := stlport_shared
#APP_STL := gnustl_shared

我可以通过ndk内置终端成功构建它。但我面临的问题是，当我尝试构建project（build->Rebuild）@user1007302时，它会抛出错误-最好（1）说明您正在执行的确切步骤（以及如何执行），以及（2）请说明您遇到的确切错误消息。到目前为止，这是关于您向我们提供的所有信息：“…错误数，如对{X}的未定义引用…”。您可以通过单击“编辑”将信息添加到问题中。
