/usr/local/include/opencv2/legacy/legacy.hpp:2667: error: 'GenericDescriptorMatcher' was not declared in this scope
     virtual Ptr<GenericDescriptorMatcher> clone( bool emptyTrainData=false ) const;
               /usr/local/include/opencv2/legacy/legacy.hpp:1750: error: 'cv::EM' has not been declared
     CvEMParams( int nclusters, int cov_mat_type=cv::EM::COV_MAT_DIAGONAL,

原因;opencv先装的2.4.9版本，随后装3.0版本，导致兼容性出现的问题

解决：如果只用2.4.×版本，就没有这个问题
