(Target machine: Wandboard quad version c, Host machine Ubuntu 14.04,and using Yocto Jethro branch)
I am trying to compile the sample opencv code.
I have created a recipe following the instruction yocto manual.
Initially I have added all the libraries related to openCv
by referring the below link.
www.engcore.com/2014/02/building-opencv-2-4-x-for-freescales-imx6-bsp-yocto
Then i gave bitbake core-image-x11.
I was able to build successfully.
(I verified the building of the cpp file by creating a simple .cpp file, It compiled correctly)
Next, I created a recipe and added the .cpp code related to opencv.Changed the recipe.bb file to compile .cpp file.
I am not able to compile the recipe .
Please let me know the steps followed are correct or not.
Below is the error.
In `main':
| helloworld.cpp:(.text+0x68): undefined reference to `cv::VideoCapture::VideoCapture()'
Any additional library i need to include in the .bb file while building receipe?
Below is the source code used for building!!!
#include <stdio.h>
#include <opencv2/opencv.hpp>
#include <iostream>
int main(int, char**) {
cv::VideoCapture vcap;
cv::Mat image; // This works on a D-Link CDS-932L
const std::string videoStreamAddress = "http://<username:password>@<ip_address>/video.cgi?.mjpg"; //open the video stream and make sure it's opened
if(!vcap.open(videoStreamAddress)) {
std::cout << "Error opening video stream or file" << std::endl;
return -1;
}
for(;;)
{
if(!vcap.read(image)) {
std::cout << "No frame" << std::endl;
cv::waitKey();
}
cv::imshow("Output Window", image);
if(cv::waitKey(1) >= 0)
break;
}
}
