How do I wrap the OpenCV InputArray class method getMat in C?
Here is my attempt:
my .cpp
#include "opencv_generated.hpp"
using namespace cv;
using namespace std;
using namespace flann;
using namespace cvflann;
extern "C" {
Mat* cv_InputArray_getMat(Mat* self) {
return new Mat(self->getMat);
}
}
my .hpp
#include <opencv2/opencv.hpp>
#include <vector>
#ifndef __OPENCV_GENERATED_HPP
#define __OPENCV_GENERATED_HPP
using namespace cv;
using namespace std;
using namespace flann;
using namespace cvflann;
extern "C" {
Mat* cv_InputArray_getMat(Mat* self);
}
I compile it with this
g++ -Wall -shared -fPIC -o libcl-opencv-glue.so cl-opencv-glue.cpp
I get this error:
root@w-VirtualBox:/home/w/opencv-master/glue#
g++ -Wall -shared -fPIC -o libopencv-glue.so opencv-glue.cpp
opencv-glue.cpp: In function ‘cv::Mat* cv_InputArray_getMat(cv::Mat*)’:
opencv-glue.cpp:9:30: error: ‘class cv::Mat’ has no member named ‘getMat’
return new Mat(self->getMat);
^
opencv-glue.cpp:10:5: warning: control reaches end of non-void function
[-Wreturn-type]
}
^
Normally when i wrap c++ opencv functions in c i use a opaque Mat* pointer to stand in for the InputArray function parameters im wrapping. I tried substituting a opaque InputArray* pointer for the Mat* in every different combination but got longer error message list the more InputArray* substitutions I made.....Any advice is much valued
Thank you.
