【问题描述】：
我在 C 中有一个 opencv 代码：
#ifdef _CH_
#pragma package <opencv>
#endif
#ifndef _EiC
// motion templates sample code
#include "cv.h"
#include "highgui.h"
#include <time.h>
#include <math.h>
#include <ctype.h>
#include <stdio.h>
#endif
这些头文件。
如果我使用
运行它gcc `pkg-config --cflags --libs opencv` motempl_temp.c -o opencv
我得到错误：

所有头文件都在路径/usr/local/include/opencv文件夹中，这包含在路径变量中。
