hi, i use ndk-build to compile my opencv code for android.I have successful experience on the

work.but,today i fail to success.this is my log under ndk-build:

/cygdrive/e/EclipseSomkeDetect/obj/local/armeabi/libopencv_highgui.a(cap_android.o): In

function `CvCapture_Android::convertYUV420i2BGR(int, int, unsigned char const*, cv::Mat&,

bool, bool)': cap_android.cpp:(.text._ZN17CvCapture_Android18convertYUV420i2BGREiiPKhRN2cv3MatEbb+0x124):

undefined reference to `cv::cvtColor(cv::_InputArray const&, cv::_OutputArray const&, int,

int)' /cygdrive/e/EclipseSomkeDetect/obj/local/armeabi/libopencv_androidcamera.a(camera_activity.o):

In function `CameraWrapperConnector::getPathLibFolder()': camera_activity.cpp:(.text._ZN22CameraWrapperConnector16getPathLibFolderEv+0x38): undefined

`/cygdrive/e/EclipseSomkeDetect/obj/local/armeabi/libSmokeDetect.so' failed make: * [/cygdrive/e/EclipseSomkeDetect/obj/local/armeabi/libSmokeDetect.so] Error 1

could any expert tell me what is problem?several weeks ago,i compile opencv code successfully

which include no cvcapture func .My current c++ code uses cvcapture func and could not link

successfully.any message would be appreciated.i uses D:\OpenCV-2.3.1-beta1-android-bin.Is it a

bug in beta?
