Question

我已经能够使用以下教程成功地将opencv与Qt集成：

How to link opencv in QtCreator and use Qt library

但是，当我尝试在.cpp文件中编写行#include "opencv/cv.h时，qt会抛出一个错误：

D:\opencv\opencv_bin\install\include\opencv2\flann\saving.h:113: error: exception handling disabled, use -fexceptions to enable
     throw FLANNException("Invalid index file, cannot read");
                                                           ^

我不确定这是qt问题还是opencv安装问题。

谢谢iHarob。解决方案是添加＆＃34;例外＆＃34;到项目文件中的CONFIG变量（* .pro文件）：

CONFIG + =例外这需要传递正确的编译器标志。答案可以在这里找到： How to enable exception handling in mingw
