Hi, this is my first attempt with Qt, i failed some installation tries but with the Nokia SDK installer everything worked fine :)
I successfully installed OpenCV 2.4.2 and they run well with visual studio 2010, but now i want to try developing with Qt. I made a very simple example code:
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
int main() {
cv::Mat image= cv::imread("img.jpg");
cv::namedWindow("My Image");
cv::imshow("My Image",image);
cv::waitKey(5000);
return 1;
}
but i have tons of error while building :(
here the full console output

i'm using Windows 8 but i don't think this can be a great problem..
Qt Creator version: 2.4.1
Qt for Desktop version 4.8.1
i even tried using this in prova1.pro:
LIBS += -C:\OpenCV2.4.2\build\x86\vc10\lib\*.lib
and LOT of other tries.. but always with this or other errors :(
what i'm doing wrong?
