使用__declspec（dllexport）在'（'标记之前进行预期的构造函数，析构函数或类型转换

Question

我已经浏览过关于同一错误的几篇文章，并且似乎在编译器找不到与签名匹配的构造函数时会发生这种情况？

但是我不能排除这种可能性，因为我的情况大不相同-它具有__declspec(dllexport)并且我不确定这是否是导致问题的元凶。

这是错误消息：

这是我的ColorCorrection.hpp文件...

#ifndef COLOR_CORRECTION_HPP
#define COLOR_CORRECTION_HPP

#include <vector>
using namespace std;

__declspec(dllexport) int VignettingCorrectionUsingRG(unsigned char* pImage, int ht, int wd, vector<double>& vp);

#endif

非常感谢您的提前帮助...
