C++ 将OpenCV与Qt链接时出错

当我运行代码时，会出现如下错误：

D:\ubunto\OpenCV\OpenCV\build\include\opencv2\imgproc\imgproc.hpp:50:错误：opencv2/core/core.hpp:没有这样的文件或目录

我不知道这是因为opencv链接还是其他原因

你可以在下面找到我的代码

格式1.h

---

首先，出现此错误是因为编译器无法从

#include

中找到

core.hpp

，无法将

包含到
imgproc.hpp
中。
我想您可以尝试将您的
INCLUDEPATH
更改为：

INCLUDEPATH+=-I“D:\ubunto\OpenCV\OpenCV\build\include\”
或
INCLUDEPATH+=-I“D:\ubunto\OpenCV\OpenCV\build\include\opencv2\imgproc”


INCLUDEPATH+=D:\ubunto\OpenCV\OpenCV\build\include\opencv2\core


等等
第二，您将动态库链接错误。你应该写：

LIBS+=-L“D:\ubunto\OpenCV\OpenCV\build\x86\mingw\bin“-lopencv\u core-lopencv\u imgproc
您应该通过以下方式链接库：
-l

我希望它能帮助你。
斜线划错了。反斜杠
\
具有特殊含义。在qt目录分隔符中，使用常规斜杠
/
（qt将其转换为windows标准）

另外，这个
LIBS+=…bin*.dll
也是错误的，请参见备选答案。
未找到的标题是编译，而不是链接器问题。Islam，你的.pro仍然错误
qmake
无法分析定义
LIBS
部分。查看我的代码
LIBS+=-L“D:\ubunto\OpenCV\OpenCV\build\x86\mingw\bin”-lopencv\u core和其他
