Qt中使用mingw如何配置qt+opencv，50分高贴

[hanbing6023]

在pro中已经添加如下代码
INCLUDEPATH+= D:\OpenCV\Opencv3.2_mingw5.3.0\install\include\opencv2

LIBS+= D:\OpenCV\Opencv3.2_mingw5.3.0\install\x86\mingw\lib\libopencv_videostab320.dll.a
声明的是，mingw是直接自己用积分从网站上下的
然后程序一旦运行就直接异常结束
Starting C:\Users\Administrator\Desktop\QT\build-untitled34-Desktop_Qt_5_8_0_MinGW_32bit-Debug\debug\untitled34.exe...
程序异常结束。

我前一段时间 刚弄了，没有任何难度，唯一不同的是，Opencv我是自己编译的。cmake就两条命令。

编译通过了,但是运行的时候粗问题了吧. 提供三个步骤 1.把libopencv*.dll和相应的依赖都 拷贝到你的exe目录里面. 2.如果上面的依赖找全了,还是崩溃,那么再把Qt相关的库拷贝到exe目录,点击运行exe,它会提示你少了什么.一个一个的找全. 3.如果上面的步骤都不能起作用,那么恭喜你, 基本可以排除目录问题,很可能是你的opencv的版本和mingw或者Qt库不兼容.你需要自己编译opencv. 以上,好运.

我曾经也遇到过楼主的问题，我的处理方法就是 自己下载opencv的源码，然后编译。这样就可以很完美在Qt上面使用opencv了

这里有我收集和我自己编译所碰到的问题的记录，可以参考一下，希望对你有帮助： qt opencv配置 (Qt 5.7.0 + opencv3.1.0 + cmake-3.4.1-win32-x86) http://blog.csdn.net/qqwangfan/article/details/52585999
