安卓 jni "No Rule to make Target issue"

Question

我正在尝试编译从下面的链接获得的项目。
Github project fmpeg. 但是在编译它以使用 andriod ndk 版本 5 创建 .so 文件时，我遇到了以下问题。请建议我解决它。

make: *** No rule to make target `/cygdrive/D/Shakthi/jhotovy/jhotovy-android-ffmpeg-fab1412/Project/jni/ffmpeg/ffmpeg.c', needed by `/cygdrive/D/Shakthi/jhotovy/jhotovy-android-ffmpeg-fab1412/Project/obj/local/armeabi/objs/ffmpeg/ffmpeg/ffmpeg.o'.  Stop.

我的 Android.mk 文件代码。

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE  := ffmpeg

FFMPEG_LIBS := $(addprefix ffmpeg/, \
 libavdevice/libavdevice.a \
 libavformat/libavformat.a \
 libavcodec/libavcodec.a \
 libavfilter/libavfilter.a \
 libswscale/libswscale.a \
 libavutil/libavutil.a \
 libpostproc/libpostproc.a )

OGG_LIBS := $(addprefix libogg/output/lib/, \
 libogg.a )

VORBIS_LIBS := $(addprefix libvorbis/output/lib/, \
 libvorbis.a \
 libvorbisenc.a \
 libvorbisfile.a )

THEORA_LIBS := $(addprefix libtheora/output/lib/, \
 libtheora.a \
 libtheoraenc.a \
 libtheoradec.a )

LOCAL_CFLAGS += -g -Iffmpeg -Ivideokit -Wno-deprecated-declarations 
LOCAL_LDLIBS += -llog -lz $(FFMPEG_LIBS) $(THEORA_LIBS) $(OGG_LIBS) x264/libx264.a
LOCAL_SRC_FILES := ffmpeg_android/ffmpeg_android.c ffmpeg/ffmpeg.c ffmpeg/cmdutils.c

include $(BUILD_SHARED_LIBRARY)

# Use to safely invoke ffmpeg multiple times from the same Activity
include $(CLEAR_VARS)

LOCAL_MODULE := ffmpeginvoke

LOCAL_SRC_FILES := ffmpeg_invoke/ffmpeg_invoke.c
LOCAL_LDLIBS    := -ldl

include $(BUILD_SHARED_LIBRARY)

您是否按照 "How to build it" 中的说明进行操作？ ?
