安卓 NDK : Aborting stop?

Question

我正在为 android 开发 ffmpeg。我已经成功编译 ffmpeg-2.0.1 之后，我在 NDK 的 sources/ffmpeg-2.0.1/android/arm 中将 Android.mk 文件设为

      LOCAL_PATH:= $(call my-dir)

      include $(CLEAR_VARS)

      LOCAL_MODULE:= libavcodec

      LOCAL_SRC_FILES:= lib/libavcodec-55.so

       LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include

      include $(PREBUILT_SHARED_LIBRARY)

之后制作android项目，android项目中的Android.mk文件如下

  LOCAL_PATH := $(call my-dir)

    include $(CLEAR_VARS)

   LOCAL_MODULE    := tutorial01
   LOCAL_SRC_FILES := tutorial01.c
   LOCAL_LDLIBS := -llog -ljnigraphics -lz 
   LOCAL_SHARED_LIBRARIES := libavformat libavcodec libswscale libavutil

   include $(BUILD_SHARED_LIBRARY)
    $(call import-module,ffmpeg-2.0.1/android/arm)

但显示有问题

 *** Android NDK: Aborting    .  Stop.

   /home/tech/Documents/roman10/ndk/android-ndk-r9c/build/core/prebuilt-library.mk
   C/C++ Problem

我的NDK是android-ndk-r9c，系统是ubuntu-13.04，请大家指导一下。

提前致谢。

见 Android.mk structure首先。

需要像这样更改 Android.mk 文件:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE    := ffmpeg
LOCAL_SRC_FILES := libs/ffmpeg.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE    := final_ffmpeg
LOCAL_SRC_FILES := ffmpeg.cpp
LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -llog
LOCAL_PREBUILTS := libs/ffmpeg.so
#libavformat libavcodec libswscale libavutil
include $(BUILD_SHARED_LIBRARY)

p/s:当像这样将数据放在一起时，我也会遇到 Android NDK : Aborting 问题:

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE:= ffmpeg
LOCAL_SRC_FILES:= libs/ffmpeg.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE    := ffmpeg
LOCAL_SRC_FILES := ffmpeg.cpp
LOCAL_SHARED_LIBRARIES := ffmpeg
include $(BUILD_SHARED_LIBRARY)

此问题发生在 LOCAL_MODULE 名称重复时。

结果会帮助你:

它仍然是您需要的时候 call the C++ function in C++ file from Java file .
