Hello I am trying to do a basic imread() to get data to plug into my algorithm, but it seems my Vivado HLS cannot find all the linkers. What flags/includes/linker paths do I need to add to the tool so it can find the OpenCV on my system? Does HLS use the OpenCV on the system or does it automatically install/compile its own version inside the tool? Are the functions like imread etc included in Xilinx's special OpenCV library headers?
Here is my basic code
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <iostream>
#include "haar_fusion_avg.h"
#include <hls_video.h>
#include <hls_opencv.h>
#include "ap_int.h"
#include <hls_stream.h>
using namespace cv;
using namespace std;
int main(int argc, char **argv)
{
AXI_STREAM video1;
Mat image;
image = imread("lichtenstein_blur_bottom_right.png", CV_LOAD_IMAGE_COLOR);
return 0;
}Here are the errors I get when I try to Run C Simulation.
