but I have tested this so using ldd command:

use command followed on my computer : nm -C libopencv_video.so.3.0 | grep calcOpticalFlowPyrLK cv::calcOpticalFlowPyrLK(cv::_InputArray const&, cv::_InputArray const&, cv::_InputArray const&, cv::_InputOutputArray const&, cv::_OutputArray const&, cv::_OutputArray const&, cv::Size_<int>, int, cv::TermCriteria, int, double)

It's different with the symbol cv::calcOpticalFlowPyrLK(cv::_InputArray const&, cv::_InputArray const&, cv::_InputArray const&, cv::_OutputArray const&, cv::_OutputArray const&, cv::OutputArray const&, cv::Size, int, cv::TermCriteria, int, double)

so the linker say:undefined reference tocv::calcOpticalFlowPyrLK(cv::_InputArray const&, cv::_InputArray const&, cv::_InputArray const&, cv::_OutputArray const&, cv::_OutputArray const&, cv::OutputArray const&, cv::Size, int, cv::TermCriteria, int, double)

but why ? Is the opencv source code different ?
