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.

Configure individual interfaces. Configure individual terminal lines. 2. Refer to the exhibit. Host A attempts to establish a TCP/IP session with host C. During this attempt, a frame was captured with the source MAC address 0050.7320.D632 and the destination MAC address 0030.8517.44C4. The packet inside the captured frame has an IP source address 192.168.7.5, and the destination IP address is 192.168.219.24. At which point in the network was this packet captured? leaving host A leaving ATL leaving...
