linux 中OpenCV 的编译。

linux下Opencv的简单程序：



#include "highgui.h"

using namespace cv;



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

{

	Mat src;

	src=imread("lena.jpg");

	namedWindow("src");

	imshow("src",src);

	waitKey(0);

	return 0;

}

编译方法:
1、 g++ test.cpp `pkg-config opencv --libs --cflags opencv` 编译没问题，正确。也能够执行
2、 g++ `pkg-config opencv --libs --cflags opencv` test.cpp 编译错误，不成功。
错误提示：

请指点。
