Code::Blocks и OpenCV, underfined reference to ... Опции

[Игорь]

Вобщем, пытаюсь пользоваться opencv, но не получается. Проблема вроде-как в линковке т.к. выползает очень много "underfined reference to".

Вот как настраивал (компилятор, кстати, MinGW):

1) Создал глобальную переменную cv, где:

base C:\CV\opencv
include $(#cv)\build\include
lib $(#cv)\build\x86\mingw\lib

2) Настроил компилятор:

Comp. and debug. --> Search dir. --> Compiler добавил $(#cv.include)
Comp. and debug. --> Search dir. --> Linker добавил $(#cv.lib)

Код (на C):

#include <opencv/cv.h>
#include <opencv/highgui.h>

int main (int argc, char *argv[])
{

    int width = 640;
    int height = 480;

    CvPoint pt = cvPoint(height / 2, width / 2);

    IplImage* bkg = cvCreateImage(cvSize(height, width), 8, 3);

    cvSet(bkg,cvScalar(0, 0, 0, 0), NULL);

    CvFont font;

    cvInitFont(&font, CV_FONT_HERSHEY_COMPLEX,1.0, 1.0, 0, 1, CV_AA);

    cvPutText(bkg, "OpenCV Step By Step", pt, &font, CV_RGB(150, 0, 150));

    cvNamedWindow("Hello World", 0);

    cvShowImage("Hello World", bkg);

    cvWaitKey(0);

    cvReleaseImage(&bkg);

    cvDestroyWindow("Hello World");

    return 0;
}

Вывод:

Наверное опять что-то упустил.
В линуксе всё это как-то поще было по-моему.... Избаловал он меня....
