error in necessitas while use openCV libs



I'm programming in QT for android device and need to use openCV for capture from camera. I already used Qt creator and linked openCV and used camera, but in Qt for android (necessitas) when build program, show this errors:

first I download latest version of openCV and build it and then use libs. also in





project.pro





add this lines:







INCLUDEPATH += "C:\OpenCV2.3.1\include\opencv"

LIBS +="C:/OpenCV2.3.1/libs/armeabi-v7a/libopencv_androidcamera.a" \

"C:/OpenCV2.3.1/libs/armeabi-v7a/libopencv_calib3d.a" \

"C:/OpenCV2.3.1/libs/armeabi-v7a/libopencv_calib3d_pch_dephelp.a" \ .

...







can necessitas support openCV? why show this errors?





sorry for my English.

  1. find and add libtiff.a, it may be in opencv 3rd party libraries directory.

Slow Android emulator

I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
