[opencv 4.0.0 installation] Failed build project
Hi i want to learn computer vision and this first time using opencv.
Please guide me to fix my error.
Step to reproduce :
1. I follow this step : https://docs.opencv.org/3.4/d7/d9f/tutorial_linux_install.html
2. Eclipse oxygen 3 C/C++
3. Set include path : /usr/local/include/opencv2
4. Set library : /usr/local/lib
5. Call libraries : opencv_core, opencv_high_ui, opencv_imgcodecs
6. Create main.cpp just for test
#include <opencv2/opencv.hpp>
using namespace cv;
int main(int argc, char** argv) {
Mat inputImage = imread(argv[1]);
imshow("Input Image", inputImage);
waitKey(0);
return 0;
}
Last commit opencv 000a13b6a35f65eb04e5c78721364406718f5d81 and for opencv_contrib 2b5eca6e1726afa2c179da672ad3a79a019da185.
Then when i build my project i got :
