Just want to quickly do an openCV helloworld:
#include <iostream>
#include <opencv2/opencv.hpp>
using namespace std;
using namespace cv;
int main()
{
Mat srcImage = imread("lena.jpg");
imshow("image",srcImage);
waitKey(0);
return 0;
}
Compile:
g++ `pkg-config opencv --cflags` opencv.cpp -o opencv `pkg-config opencv --libs`
but I got this error:
OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvShowImage, file /home/boris/Softwares/openCV/opencv/modules/highgui/src/window.cpp, line 611 terminate called after throwing an instance of 'cv::Exception' what(): /home/boris/Softwares/openCV/opencv/modules/highgui/src/window.cpp:611: error: (-2) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function cvShowImage
Something is wrong with QT?
sudo apt-get install libqt4-dev
cmake -D WITH_QT=ON ..
make
sudo make install
