我必须使用名为 RTMaps(基于 block 的编程环境)的软件工具来进行基于视觉的实时控制。我习惯了 OpenCV 和 RTMaps 支持在 C++ 中创建我自己的 block ，所以我用 Opencv 编写了我的图像处理算法。
问题是，在 RTMaps 中，Iplimage 已经被定义为一种数据类型，所以当我尝试将我的代码集成到一个新 block 中时，我得到了这个讨厌的错误:
我怎样才能克服这个问题，而不是对同一类型进行双重声明？我需要 OpenCV 库中的其他函数/数据类型，但我无法更改 RTMaps 核心。

最佳答案
有一个宏告诉 RTMaps 避免重新定义 IplImage 结构。在您的 header 中，您需要按以下顺序编写您的包含:
#include <opencv2/opencv.hpp> //Or any other OpenCV header
#define __IPL_H__
#include "maps.hpp"
