Not declared in the scope

edit

Hello. Yesterday I finally install opencv and my first example works fine. But second not, here's my code .

int main()

{

IplImage * img = cvLoadImage("obrazek.jpg");
cvNamedWindow("Przetworzone");
cvNamedWindow("Nie przetworzone");
cvShowImage("Przetworzone",img);
IplImage * img_wyj = cvCreateImage(cvGetSize(img),IPL_DEPTH_8U,3);
cvSmooth(img,img_wyj,CV_GAUSSIAN,11,11);
cvShowImage("Nie przetworzone",img_wyj);
cvWaitKey(0);
cvReleaseImage(&img);
cvReleaseImage(&img_wyj);
cvDestroyWindow("Przetworzone");
cvDestroyWindow("Nie przetworzone");

return 0;

}

path_to_the_open_cv/main.cpp:29: error:'CV_GAUSSIAN' was not declared in this scope path_to_the_open_cv/main.cpp:29: error:'cvSmooth' was not declared in this scope In other example I got error like this. path_to_the_open_cv/main.cpp:14: error:'Cv_Window_Autosize' was not declared in this scope when I want to do this(window called "Kamera" already exist).

cvNamedWindow("Kamera",Cv_Window_Autosize);

Im using QT Creator and im including opencv2/core/core.hpp, opencv2/highgui/highgui.hpp, opencv2/highgui/highgui_c.h.
